Free APIs catalog (journalism-curated)
A short list of free APIs that work for journalism, research, and weekend projects under current free-tier conditions. The value here is curation under verified 2026 free-tier limits — not coverage. For breadth, defer to the canonical aggregator below.
Canonical breadth reference
For a near-complete inventory of free public APIs across every category (1000+ entries, actively maintained), use:
Not archived, last commit verified 2026-05-09, 4,600+ commits, 6,000+ merged PRs. When you need an API outside the categories below, search there first.
This skill curates the journalism-relevant subset.
Recently sunset / changed (don't use)
| API | Status | What to use instead |
|---|
| IEX Cloud | Fully retired 2024-08-31. https://iexcloud.org/ | Alpha Vantage, Tiingo IEX, Financial Modeling Prep, Polygon |
| CrowdTangle | Sunset 2024-08-14 | Meta Content Library (academic/non-profit-research only — most journalists ineligible). https://transparency.meta.com/researchtools/meta-content-library/ |
| ProPublica Congress API | Retired 2024-07-10, repo archived. https://www.propublica.org/nerds/congress-api-update | api.congress.gov (Library of Congress, free with api.data.gov key) |
| X / Twitter API free tier | Effectively eliminated for new developers as of Feb 2026; pay-per-use only. Uncertain on exact figures (provider pricing page returned 402). Treat as paid. | No free replacement; closest free alternatives are Bluesky Jetstream + Mastodon |
| Reddit API | Free for research/non-commercial only since June 2023; paid for commercial use. https://www.reddit.com/wiki/api/ | (Same — usable for journalism research, prohibited for monetized products) |
| Hugging Face Inference API | Rebranded to Inference Providers (router across 20+ providers). Free users now get $0.10/month in credits, down from previous unmetered free tier for many models. https://huggingface.co/docs/inference-providers/pricing | Free tier still works for low-volume / embeddings; paid for production |
Journalism-curated short list
All entries below verified against provider pages on 2026-05-09 unless marked uncertain. Always confirm rate limits against the provider's live developer docs before depending on them in production.
News monitoring
| API | Free tier | Notes |
|---|
| GDELT 2.0 | Fully free, no auth | Global news + knowledge graph, updates every 15 min, BigQuery-mirrored. Strong for cross-border / longitudinal monitoring. |
| NewsAPI | 100 req/day, 24h delay, 1mo window, dev-only | Commercial use prohibited on free tier. Not usable in shipped products. |
| GNews | 100 req/day, 30d window, 12h delay, non-commercial | 10 articles/request cap. |
| Mediastack | 100 req/month, 30-min delay | Functionally a demo. |
| NYT Article Search / Top Stories | Free with key, daily cap (uncertain — verify) | Solid for archival queries. |
Social platforms (post-API-monetization landscape)
| API | Free tier | Notes |
|---|
| Bluesky Jetstream | Public WebSocket firehose, no auth | Real-time public-post stream. 4 official instances. Caveat: not formally part of AT Protocol — no long-term stability commitment. |
| Bluesky AppView | Public read endpoints, 3000 req / 5min IP-based | Auth needed for write ops. Profiles, posts, search. |
| Mastodon | Per-instance, OAuth, public endpoints often unauth-readable | Federated — coverage is server-by-server. |
| Threads (Meta) | Free pricing not surfaced on docs page (uncertain — verify) | Read/post/reply/search/insights/webhooks. |
| Reddit | 100 QPM authenticated, 10 QPM unauthenticated, non-commercial only | Adequate for OSINT/research, prohibited for monetized products. |
| Meta Content Library | Academic / non-profit researchers only | Most journalists need a university partner to qualify. |
| TikTok Research API | Academic-affiliated researchers only | Same eligibility gate as MCL. |

| Financial Modeling Prep | Free tier exists, paid for production | IEX Cloud successor. |
Archive / preservation
| API | Free tier | Notes |
|---|
| Wayback Machine | Free | Availability JSON, Memento, CDX server. Save Page Now exposes programmatic submit. |
