Webz.io vs. NewsData.io: Live News API Benchmark

We tested the Webz.io News API and NewsData.io against the same topics, countries, languages, search operators, and publication window.

The result was consistent: Webz.io returned substantially more matching news, delivered full article text in every sampled record, and responded faster.

Across the aligned 48-hour window, Webz.io reported 5,513,536 matching articles, compared with 929,581 from NewsData.io. Webz.io also returned more matches in every one of the 38 topic, publisher-country, and language coverage tests.

For developers building media monitoring, adverse-media screening, market intelligence, AI grounding, or any product where missed articles become data gaps, Webz.io was the stronger API in this benchmark.

How we tested the APIs

The benchmark ran on September 2, 2026 and made 156 live HTTP requests. It tested:

• 14 broad, specialist, and long-tail topics
• 12 publisher countries
• 12 languages
• Exact phrases and Boolean operators
• Title-only searches
• Domain inclusion and exclusion
• Categories and sentiment
• Duplicate and syndicated-content controls
• Source-ranking filters
• Full article content and enrichment fields
• Recent timeframes and historical access
• Pagination behavior
• Response latency

NewsData.io’s Latest endpoint covers the previous 48 hours. Webz.io normally searches a three-day crawl-time window by default, so the Webz.io requests were constrained by both publication time and crawl time to create the same 48-hour publication window: August 31, 2026 at 11:33 UTC through September 2, 2026 at 11:33 UTC.

NewsData.io was tested with the supplied free key. That plan delays results by 12 hours and excludes full article content, sentiment, short timeframes, and historical access. We treated rejected requests as account-plan restrictions rather than as proof that the underlying product has no such feature.

Coverage figures in this article are the totals reported by each API. They are not independently verified unique-article counts, and aggregate topic, country, and language totals may include the same article in more than one query. The benchmark therefore measures the candidate result set exposed by each API, not human-judged relevance for every result.

1. Webz.io returned 5.93x more news in the aligned window

The clearest difference was overall coverage.

For all news published within the same 48-hour window, Webz.io reported 5,513,536 matches. NewsData.io reported 929,581.

That gave Webz.io a 5.93x coverage advantage in the broadest test.

The difference was not limited to a few popular subjects. Webz.io returned more matches in all 14 topic queries, all 12 publisher-country queries, and all 12 translated-language queries.

NewsData.io’s free-plan delay may account for part of the difference. It does not explain away the consistency of the result across all 38 coverage comparisons.

Topic coverage

Webz.io returned more reported matches for every topic. Across all 14 queries, its aggregate count was 4.54x higher. The median advantage across individual topics was 4.23x.

Query	Webz.io	NewsData.io	Webz.io advantage
Artificial intelligence	28,564	8,632	3.31x
Aviation safety	410	259	1.58x
Bitcoin	36,993	3,403	10.87x
Climate change	7,782	3,707	2.10x
Earthquake	3,320	836	3.97x
Federal Reserve	7,979	2,389	3.34x
Gaza	12,919	3,127	4.13x
Infostealer	307	54	5.69x
NVIDIA	19,200	4,408	4.36x
OpenAI	20,032	3,394	5.90x
Rare earth minerals	160	29	5.52x
Roblox	3,379	869	3.89x
Semiconductor	9,626	2,228	4.32x
Ukraine	36,088	7,798	4.63x

The difference appeared in high-volume subjects such as Bitcoin and Ukraine, but also in narrow searches such as infostealer, aviation safety, and rare earth minerals.

That long-tail coverage matters in monitoring applications. The articles with the greatest operational value are often not the ones repeated by major publishers. They may come from a regional outlet, an industry publication, a small local source, or a specialist site that only occasionally covers the subject.

A larger result count does not by itself prove that every result is relevant. It does show that Webz.io gave the application a much larger candidate set from which to rank, filter, classify, or alert.

Publisher-country coverage

We also ran unqualified news searches filtered by the publisher’s country. Webz.io returned more matches in all 12 countries, with an aggregate advantage of 3.51x.

Publisher country	Webz.io	NewsData.io	Webz.io advantage
Australia	20,421	17,634	1.16x
Brazil	256,257	20,762	12.34x
Canada	35,581	26,443	1.35x
Germany	228,874	55,678	4.11x
United Kingdom	91,305	44,752	2.04x
Israel	13,625	6,628	2.06x
India	303,419	101,012	3.00x
Japan	137,531	28,007	4.91x
Mexico	108,419	19,451	5.57x
Nigeria	20,693	6,727	3.08x
United States	598,610	187,429	3.19x
South Africa	6,285	4,631	1.36x

The gap was especially large in Brazil, Mexico, Japan, and Germany. Even in the closest comparisons, Webz.io returned the larger match set.

Publisher-country classification may differ between providers, so these figures should be read as a comparison of API behavior rather than a definitive count of each country’s news output.

Language coverage

For each language, we translated the exact phrase “artificial intelligence” and combined it with the corresponding language filter.

Webz.io returned more reported matches in all 12 tests. Its aggregate count was 5.97x higher, and its median advantage per language was 6.45x.

Language	Webz.io	NewsData.io	Webz.io advantage
Arabic	11,572	1,117	10.36x
German	3,895	114	34.17x
English	26,478	8,382	3.16x
Spanish	18,267	3,628	5.04x
French	883	233	3.79x
Hebrew	249	93	2.68x
Hindi	401	51	7.86x
Japanese	1,086	246	4.41x
Portuguese	12,824	146	87.84x
Russian	8,873	42	211.26x
Turkish	10,583	663	15.96x
Chinese	4,052	1,902	2.13x

The very large ratios in Russian, Portuguese, and German may reflect differences in source coverage, phrase matching, indexing, and tokenization. They should not be interpreted as precise unique-source ratios.

The repeatable result is that Webz.io returned the larger candidate set in every tested language, including Arabic, Hebrew, Hindi, Japanese, Russian, and Chinese.

The vendors’ own published coverage figures point in the same direction, although vendor source counts are not standardized. Webz.io reports more than 350,000 news sources, more than 3.5 million articles per day, and support for 170+ languages. NewsData.io reports more than 102,000 sources and 89 languages.

2. Webz.io included full article text in every sampled record

Finding an article is only the first step. Most monitoring and AI applications also need enough content to analyze it.

Across the aligned benchmark cases, Webz.io returned 670 sampled records. Every record contained extracted article text. The median article-body length was 3,255 characters.

NewsData.io returned 627 sampled records, but its content field contained a paid-plan placeholder in every response produced by the tested free key.

Content and enrichment field	Webz.io	NewsData.io free plan
Sampled records	670	627
Actual full article text	100%	0%
Median full-text length when present	3,255 characters	—
Extractive summary	53.1%	0%
Document sentiment	53.0%	0%
Topics	51.8%	No equivalent populated field in the sample
Organizations	23.7%	0%
Locations	20.9%	0%
People	14.3%	Not documented as a standard response field

This changes what developers can build from the response.

Full article text supports:

• Retrieval-augmented generation and LLM grounding
• Custom summarization
• Embedding generation and semantic search
• Adverse-media classification
• Entity and relationship extraction
• Claim and event detection
• Topic modeling
• Custom sentiment or risk scoring
• Evidence snippets for alerts and investigations

A title and short description can tell an application what the article appears to be about. The article body gives the application the evidence needed to decide whether it is actually relevant.

Those fields were not available through the supplied NewsData.io account. Webz.io returned full text and enrichment data directly in the tested responses without a separate page-fetching step or a higher subscription tier.

3. Webz.io exposed a larger result set under every shared search test

We tested exact phrases, Boolean logic, title-only search, domain filtering, duplicate removal, source quality, and image requirements.

In every shared query shown below, Webz.io reported more matches.

Search test	Webz.io	NewsData.io	Webz.io advantage
OpenAI in the title	4,475	685	6.53x
Exact phrase “artificial intelligence”	28,773	8,609	3.34x
AI-regulation Boolean query excluding cryptocurrency	2,899	418	6.94x
Climate coverage from BBC domains	20	7	2.86x
OpenAI with duplicate or syndicated results removed	6,825	2,654	2.57x
OpenAI from higher-ranked sources	2,374	821	2.89x
OpenAI articles that include images	20,274	3,067	6.61x

The result is useful for developers who plan to apply their own ranking or classification layer. Better downstream ranking cannot recover articles that never entered the candidate set.

4. Webz.io provides a deeper query language for monitoring

News monitoring queries become complicated quickly. A useful alert may need to combine several concepts, exclude noisy meanings, restrict dates and sources, require negative sentiment, and suppress syndicated copies.

Webz.io expresses free text, exact phrases, Boolean logic, and field filters in one q expression. The query language supports:

• AND, OR, and NOT
• Exact phrases
• Parentheses and nested expressions
• Title and text field searches
• Domain inclusion and exclusion
• Country and language filters
• Categories and topics
• Publication and crawl dates
• Sentiment
• People, organizations, and locations
• Source rank
• Syndication and duplicate controls
• Wildcards
• Proximity searches

For example:

(“artificial intelligence” OR “machine learning”)

AND regulation

NOT cryptocurrency

sentiment:negative

language:english

country:US

NOT site:yahoo.com

This is useful for persistent monitoring rules because the complete search logic can be stored, versioned, and submitted as one expression.

NewsData.io uses a mix of a Boolean q value and separate request parameters. In the live test, the supplied key rejected the sentiment, full-content, six-hour timeframe, and archive probes. Its domain-exclusion probe also returned HTTP 422. Webz.io accepted the corresponding searches.

Webz.io therefore gave the tested account both broader coverage and more usable control over the result set.

5. Webz.io was 2.21x faster in the paired requests

We compared 47 first-page requests for which both APIs returned HTTP 200 under an aligned test case.

Latency measure	Webz.io	NewsData.io	Webz.io advantage
Median response time	259 ms	573 ms	2.21x faster
p95 response time	568 ms	811 ms	30% lower

Webz.io was faster in 44 of the 47 paired requests, while also returning full article text and a larger metadata set.

The latency measurement includes DNS resolution, TLS negotiation, network transfer, server processing, and response download from one Windows machine. It is a point-in-time comparison, not an uptime test or a universal performance guarantee.

The consistent result across the paired requests is still clear: Webz.io delivered the response faster in 93.6% of the tests.

6. Webz.io offers more historical depth and more results per call

The historical-access probe used a seven-day-old OpenAI query.

Webz.io returned 10,977 matching articles. NewsData.io’s Archive endpoint returned HTTP 403 under the tested free key.

Webz.io supports recent historical searches through the live API and offers a news archive going back to 2008. NewsData.io’s longest published history begins in January 2016 on its Corporate tier.

Webz.io also supports up to 100 articles in one API response. NewsData.io returns up to 10 on the free plan and up to 50 on paid plans.

The larger page size reduces the number of round trips needed to retrieve the same result set. It is especially useful for backfills, investigations, model evaluation datasets, and high-volume monitoring jobs.

7. Webz.io returns monitoring-grade metadata with the article

Webz.io’s response is designed for applications that need to inspect the article, its source, and the context around it.

Depending on availability, a News API record can include:

• Full article text
• Article title and URL
• Publication and crawl timestamps
• Authors
• Images
• Extractive summary
• Categories and topics
• Document sentiment
• People, organizations, and locations
• Source domain and country
• Domain rank
• Syndication information
• Social signals
• Source type
• Trust, fake-news, satire, and political-bias labels

This reduces the number of additional services a developer must add after retrieval. The same response can feed a search interface, an alerting system, a risk classifier, a knowledge graph, or an LLM pipeline.

8. Webz.io has no required monthly subscription for paid use

Webz.io gives every account $5 in API credit each month, with no credit card required.

After the free credit is used, the News API follows a transparent usage-based model:

• $0.01 per API call
• $0.005 per returned article
• No required monthly subscription for self-service usage
• Custom pricing for high-volume packages

At the published self-service rate, a request that returns ten articles costs $0.06.

NewsData.io’s first paid subscription is listed at $199.99 per month. Higher tiers are listed at $349.99 and $1,299.99 per month.

Pricing factor	Webz.io	NewsData.io
Free access	$5 in fresh API credit every month	Free account is delayed and excludes full content
Entry paid model	Pay as you go	$199.99 monthly subscription
Minimum self-service commitment	None	Monthly plan
Public usage pricing	$0.01 per call plus $0.005 per result	Credit bundle tied to plan
Full text in tested free response	Included	Excluded
High-volume option	Custom volume packages	Higher subscription tiers and custom plan

This model lets developers test the actual response depth, including full article text, and then pay for the usage they consume without first committing to a monthly package.

When Webz.io is the better choice

The benchmark points to Webz.io for products where missing content, receiving thin records, or relying on a shallow query model creates real costs.

Webz.io is the better fit for:

Media monitoring

The broader candidate set makes it easier to catch local, specialist, regional, and long-tail reporting. Boolean filters, exclusions, source controls, sentiment, and syndication rules help turn that coverage into useful alerts.

Adverse-media screening

Full article text gives a screening system enough context to distinguish a genuine risk event from a passing mention. Entity fields, source metadata, sentiment, and trust labels support triage and investigation.

AI and RAG applications

The API returns the article body needed for chunking, embeddings, reranking, summarization, and grounded answers. Developers do not need to fetch each publisher page separately before creating usable context.

Financial and market intelligence

Broader regional and multilingual coverage helps surface reporting outside the largest English-language publishers. Publication time, source rank, entities, and sentiment can support downstream scoring.

Brand and reputation monitoring

Nested queries can combine product names, executives, subsidiaries, competitors, negative concepts, exclusions, source types, and geographic filters in one expression.

News datasets and research

Up to 100 results per request, historical coverage back to 2008, and full text make Webz.io more practical for building corpora, conducting retrospective analysis, and evaluating models.

The bottom line

The live benchmark produced one consistent result across coverage, content depth, search control, and speed.

Webz.io:

• Returned 5.93x more news in the aligned 48-hour window
• Returned more matches in all 38 topic, country, and language tests
• Included full article text in 100% of the aligned sample
• Was 2.21x faster at the median
• Was faster in 44 of 47 paired requests
• Supported up to 100 results per response
• Offered historical coverage back to 2008
• Accepted advanced monitoring filters on the tested account

For developers building a simple list of headlines, result depth may be less important. For monitoring, intelligence, research, and AI products, it determines how much of the news you can actually find and what you can do with each article after retrieval.

Based on this benchmark, Webz.io is the stronger News API when coverage and usable article data matter.

Frequently asked questions

Which API returned more news in the benchmark?

Webz.io returned more provider-reported matches in every coverage test. It reported 5,513,536 matches in the aligned 48-hour all-news window, compared with 929,581 from NewsData.io.

Across the 14 topic queries, Webz.io’s aggregate result count was 4.54x higher. It also led all 12 publisher-country and all 12 language searches.

Was the coverage comparison based on the same time window?

Yes. Both APIs were evaluated against the same 48-hour publication window, from August 31, 2026 at 11:33 UTC through September 2, 2026 at 11:33 UTC.

Webz.io was constrained by both publication and crawl time so its normal three-day default did not inflate the comparison.

Are the coverage totals verified unique articles?

No. They are the matching totals reported by each provider. The benchmark did not download and independently deduplicate millions of records.

The figures measure how large a candidate set each API reported for the same query and time window. They should not be read as a claim that every result was unique or equally relevant.

Did the benchmark test a free or paid NewsData.io account?

It used the supplied NewsData.io free key. That plan delayed results by 12 hours and rejected full-content, sentiment, six-hour timeframe, and historical-access probes.

The article labels plan-specific findings so the comparison remains tied to the accounts that were actually tested.

Which API returned full article content?

Webz.io returned actual article text in every one of its 670 aligned sampled records. The median body length was 3,255 characters.

The tested NewsData.io free key returned a paid-plan placeholder rather than article text in its content field.

Which API was faster?

Webz.io had a median response time of 259 ms, compared with 573 ms for NewsData.io. It was faster in 44 of the 47 paired successful requests.

The result reflects one test machine, network path, account pair, and point in time. It is not a universal latency guarantee.

Which API is better for media monitoring and adverse media?

The benchmark favored Webz.io for these use cases. It returned more matches across topics, countries, and languages, and it supplied the full article body needed for classification and investigation.

Its query language also supports nested Boolean logic, field filters, sentiment, entities, source ranking, dates, and syndication controls.

Which API is better for AI grounding and RAG?

Webz.io is better suited to workflows that need the article body. Full text can be chunked, embedded, reranked, summarized, or passed to an LLM without first scraping the publisher page.

How can developers try Webz.io?

Every Webz.io account receives $5 in free API credit each month. No credit card is required. After that, developers can continue on a pay-as-you-go basis or use a volume package for larger workloads.

Start with $5 in free Webz.io API credits every month. No credit card required.
