One request, clean JSON

Hugging Face dataset search from Hugging Face: GET https://api.api.sh/huggingface/v1/datasets. Every other developer & reference endpoint works the same way.

curl "https://api.api.sh/huggingface/v1/datasets?q=squad" \
  -H "x-api-key: $APISH_KEY"
import os, requests

res = requests.get(
    "https://api.api.sh/huggingface/v1/datasets",
    params={"q": "squad"},
    headers={"x-api-key": os.environ["APISH_KEY"]},
    timeout=120,
)
res.raise_for_status()
data = res.json()

Why API.SH for developer & reference data

  • Public data only: no logins, cookies or accounts on the source sites
  • One key and one JSON shape across 15 developer & reference platforms and 482 in all
  • Blocks, retries and parsing handled for you: no scraper to maintain
  • Pay per call; failed calls cost nothing
  • Also in n8n, Zapier, Make, Google Sheets and AI agents (MCP)

Compared with other data APIs

Other providers sell each platform as a separate actor, scraper or subscription. On API.SH every developer & reference platform is under one key and one balance, priced per call on the pricing page.

Developer & reference API questions

Why use API.SH instead of each site's own API?+

Each site has its own auth, rate limits and response format. API.SH gives you one key, one JSON format and pay-per-call pricing across all of them, and covers sites with no public API.

Is there a free Wikipedia or Stack Overflow API?+

Yes. Every API.SH account gets 1,000 free credits each month, no card needed, usable on Wikipedia, Stack Overflow and every other endpoint. Paid calls start at $1 per 1,000.

Do I need API keys for GitLab, npm or Hugging Face?+

No. API.SH needs only its own key and returns public data.

Can I use it from Python?+

Yes. Every endpoint is a plain GET request returning JSON.

Is there an MCP server for AI agents?+

Yes. The API.SH MCP server lets Claude, Cursor and other MCP clients call these endpoints directly.
