The short answer
World News API is a direct filtered-article interface with explicit point costs. Event Registry adds concept and event-oriented queries. A keyword feed does not need an event ontology unless grouping and disambiguation solve a real downstream task.
| Provider | A good reason to choose it | Important caveat |
|---|---|---|
| Event Registry | A research workflow that needs concepts and events as first-class objects, not just a list of matching article URLs. | NewsAPI.ai/Event Registry is a different service from newsapi.org. Resolve concepts and distinguish articles from events before comparing quotas or result counts. |
| World News API | A filtered news application that can budget using a documented points-per-request and per-result model. | Search points and article counts are different units. A text field being available does not grant unrestricted redistribution of the publisher's article. |
Side-by-side differences
| Requirement | Event Registry | World News API |
|---|---|---|
| Search workflow | Keyword/concept queries and event-level retrieval | Text, date, geographic and entity-related filters |
| Article body | Article body and metadata depend on requested result settings | Article text and metadata in search responses |
| Archive access | Date filters and historical access depend on plan | Date-bounded search; archive coverage needs validation |
| Pagination | Article page/count parameters and SDK iterators | number and offset |
| Production access | Plan and requested result-type entitlement | Account points and content-use terms |
| Cost driver | Requested query/result type and plan limits | Base request points plus per-result points |
Pricing: make the units comparable
| Provider | Billing model | What to check |
|---|---|---|
| Event Registry | Plan-specific query and data access | Check the current plan against the requested article/event result types and archive. No universal token-to-article exchange rate is assumed. |
| World News API | Points for requests and returned results | Search News is documented as 1 point plus 0.01 points per returned result. Check daily quota and other endpoint charges separately. Checked October 28, 2026. |
For 10,000 usable articles, track duplicate rate, results per page and paid units. A request returning ten truncated articles is not equivalent to one returning a hundred licensed full-text records. Include the production-plan minimum in the comparison.
For a buying decision, calculate total spend divided by accepted outputs at your expected volume. Keep free evaluation access, paid production access, annual commitments and overages separate. We have not measured a cost or speed winner for this pair.
What changes in the integration?
| Event Registry | World News API | |
|---|---|---|
| Method and URL | POST https://eventregistry.org/api/v1/article/getArticles | GET https://api.worldnewsapi.com/search-news |
| Authentication | API key in apiKey | x-api-key header or api-key parameter |
| Inputs | JSON keyword or conceptUri, dateStart/dateEnd, resultType and apiKey | text, language, source-countries, date filters, number and offset |
| Output | Requested article results or aggregates; event queries use a separate interface. | news records and availability/pagination metadata; quota usage in response headers. |
Event Registry: migration check
Concept URIs are provider identifiers, not plain keyword strings. Keep event grouping separate from article deduplication and re-resolve entities when moving to a different service.
World News API: migration check
Map hyphenated parameter names explicitly and persist quota headers. Offset paging and provider availability limits should not be treated as a guaranteed complete export.
How to test them fairly
- Prepare a fixed set of entity names, ambiguous names, exact phrases and multilingual topics. Pin the publication window and record the retrieval time.
- Score a blinded sample for topic relevance and entity precision. Count unique stories separately from syndicated copies and repeated URLs.
- Measure publication-to-availability delay on a monitored source set. Article timestamps alone do not reveal when the provider indexed them.
- Check missing bodies, truncation, source URLs and archive cutoffs on the exact plan. Store metadata and hashes where article-storage rights are not established.
- Record requests, pagination, credits or points per usable article. Confirm publisher rights and permitted storage/redistribution independently of API access.
Record the plan, request settings, time window and acceptance rules with every run. That makes a later result interpretable when a vendor changes a model, source set or pricing tier.
Prefer a common request format?
POST /api/v1/news/searchReview the request contract and tell us the coverage you need. Access requires enablement; this endpoint does not execute or bill requests yet.
