# GitHub REST API — 403 without a User-Agent; unauthenticated rate limit 60/hour

**Observed 2026-09-25** by direct HTTPS requests to `https://api.github.com/rate_limit`.

- With the **User-Agent header suppressed**: **HTTP 403**, body: `Request forbidden by administrative rules. Please make sure your request has a User-Agent header`.
- With **any** User-Agent (even `curl/8.17.0`): **HTTP 200**.
- Unauthenticated **`X-RateLimit-Limit: 60`** (per hour); `X-RateLimit-Remaining` decrements per request; `X-RateLimit-Reset` is a unix timestamp.

**Documented vs observed:** GitHub documents the User-Agent requirement; observed behaviour matches. The trap for an agent: an HTTP client that omits a User-Agent gets a 403, not a rate-limit or auth error.
