# Plans & Pricing


The APIs.io API and [MCP server](./mcp-server) are free to try. Paid tiers raise your rate limits
and unlock the **industries**, **regions**, and **ratings** endpoints (and Pro/Business-only paths
as they ship). Authenticate with your GitHub account; pay with Stripe.

## How it works

1. **Log in with GitHub** — you're issued a free **Starter** API key instantly.
2. Send it as an `X-API-Key` header:
   ```bash
   curl -H "X-API-Key: <your key>" "https://apis.io/api/v1/industries"
   ```
3. **Upgrade to Pro or Business** from your [account](./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](./authentication) and
[Rate Limits](./rate-limits) for details.
