ReqKey

name: ReqKey
description: 'ReqKey is out-of-band API key authentication, usage credits, rate limiting and request analytics as a service
  for teams that sell or expose an API. It never sits in front of customer traffic: your own middleware makes one call to
  POST /key/validate per request, which checks the key, deducts a credit from that customer''s pool and records the decision,
  typically in under 5ms over a reused connection. The defining design choice is that credits and rate limits live on the
  CONSUMER rather than the key, so issuing a customer fifty keys never multiplies their plan into fifty quotas and disabling
  a consumer stops all of its keys at once. Validation is Redis-backed and runs in multiple AWS regions with a global sync
  layer reconciling credit balances. A second endpoint, POST /ingest, correlates full request/response logs to a validation
  by requestId and feeds an Analytics API over two datasets. Seven first-party SDKs wrap both calls as framework middleware.'

  note: 'Renamed from MCPServer 2026-09-03 (roadmap#247): the manifest self-describes as status: candidate — a tool list derived
    from the published API contracts, not an existing server. The scorer already read the manifest and reported mcp_server
    correctly; the MCPServer type was crediting the artifact-type surfaces with a server that does not exist.'
