What this skill does

# 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:

- **public-apis/public-apis on GitHub** — https://github.com/public-apis/public-apis

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.
