Apidoor Gateway
Project-specific HTTPS gateway that Apidoor runs in front of a seller's existing upstream API. Customers call https://{slug}.apdr.io (or a verified custom domain) with an Apidoor-issued key in the X-API-Key header; Apidoor forwards the remaining path and query string to the upstream, adding the x-apidoor-proxy-secret header, and enforces per-key monthly quotas and per-minute limits. Routes are pass-through and defined by each seller's upstream, so Apidoor publishes no fixed operation list and no OpenAPI, GraphQL, AsyncAPI, gRPC or WSDL contract; Starter and Pro projects can receive signed limit webhooks (api_key.monthly_limit_reached, account.monthly_limit_reached).
