Nothing serious here today

Today is the operative word: we check PublicAPIs.io every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

api

get_api

Everything about one API by slug (from search_apis): documentation summary, endpoints, auth, pricing and links. Use before writing integration code.

apis

search_apis

Find a public API or data source for a task: use this whenever the user (or your code) needs an API, dataset or third-party service, e.g. weather, geocoding, payments, sports scores, crypto prices, jobs, LLMs. Searches 1,500+ APIs on PublicAPIs.io and returns name, description, category, link and signals (auth: none/api_key/oauth, free_tier, https). Filter with auth="none" for APIs that need no key, free=true, https=true.

compare

compare_apis

Compare 2-5 APIs side by side (auth, free tier, HTTPS, pricing, docs summary) to choose one. Pass slugs from search_apis.

Status of a deal: negotiating, agreed, awaiting_approval, awaiting_payment (payment_url is included), publishing, live (live_url), rejected. Also returns the last messages.

offerings

list_offerings

Ways to get an API listed or sponsored on PublicAPIs.io, with fixed prices, current sponsorship availability and the rules.

Ready-to-run example code for calling an API, in javascript, python or curl. Use when you are about to integrate an API into code. Verified samples are marked verified=true.

PublicAPIs.io — questions

Answers built from our own checks of this server.

What can PublicAPIs.io do?

It exposes 8 tools, read directly from the server on our last check. Among them: compare_apis, get_api, get_deal, get_quickstart, list_offerings, search_apis and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is PublicAPIs.io working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 82 of 82 checks got a reply (100.0%), average response time 2493 ms. The bar chart above shows every period we have measured.

How do I connect PublicAPIs.io?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does PublicAPIs.io need an API key?

No. PublicAPIs.io completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.
