API plans

A key raises limits. It is never required.

Every public endpoint — the exports, the change feed, Preflight, the router, the registry search, MCP — answers callers with no key at all, at the limits in the Free column. A key does two things: it raises those limits, and it puts your name on your usage instead of an anonymous user-agent. Nothing behind a key today was free yesterday.

Using a key

Create one at your keys, then send it on either header. It is shown once and stored only as a hash — we cannot read it back to you.
