Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00033 | $0.02749 |
| Opus 5 | $0.00016 | $0.01375 |
| Sonnet 5 | $0.00007 | $0.00550 |
| Haiku 4.5 | $0.00003 | $0.00275 |
Grade A, and why
free-apis-catalog scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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 |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 7d ago First seen · 140 lines · 33 tokens per session scan A 8efa266374dd
free-apis-catalog is a skill published in the GitHub repository jamditis/claude-skills-journalism (391 stars, last pushed today), licensed MIT. It adds 33 tokens to every session and 2,749 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
