APIs.io Developers - Apis

The APIs.io API and MCP server are free to try. Paid tiers raise your rate limits and unlock the industries , regions , ratings , Insights depth, and the Saved Workspace (saved searches, lists, and net-new deltas) — the same across the REST API and the MCP server. Authenticate with your GitHub account; pay with Stripe.

How it works

Log in with GitHub — you're issued a free Starter API key instantly.
Send it as an X-API-Key header:

bash

TerminalCode

`curl -H "X-API-Key: <your key>" "https://apis.io/api/v1/industries"`

Upgrade to Pro or Business from your account page (Stripe Checkout). Your key keeps working — its limits and access just increase immediately.

Without a key, requests run on the Free tier (no industries/regions/ratings). The apis.io website itself runs on an internal tier. See Authentication and Rate Limits for details.
