Documentation
Everything the gateway exposes, and how to authenticate against it.
Authentication
Every request needs a bearer key in the Authorization header. Query-string credentials
are deliberately not supported — the MCP authorization specification prohibits access tokens in the URI.
Authorization: Bearer pmcp_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
A missing, malformed, revoked, expired or unknown key returns 401.
Exceeding your rolling-24h quota returns a tool error naming the limit.

Fair use
These servers proxy public US government APIs with shared upstream rate limits
(SAM.gov's personal tier, for example, allows only 10 requests/day). Responses are cached hard, quotas
are per account, and abusive traffic is throttled. Do not present this service as an official
government data source.
