    server: https://apis.io/api/v1
    operations: 110
    gated: false
    note: Counted across every tag-split contract, not just apis-io-v1-openapi.yml — the Provider Control,
      Saved Workspace, Cohorts, Editorial, Export and Venture Capital contracts each carry operations
      the v1 aggregate does not.
  mcp:

    transport: streamable-http
    tools: 133
    gated: false
    note: Anonymous tools/list returned HTTP 200 with a full inputSchema per tool on 2026-09-11, so every
      binding below is confirmed against the live tool contract rather than a docs list.
  graphql:
    present: false
    note: /graphql in the REST contract is the catalog COLLECTION of GraphQL schemas published by other
      providers (listGraphql) — APIs.io itself serves no GraphQL endpoint.
binding_method: Preferred source of truth is the x-mcp-tool extension declared on the operation itself
  (76 operations carry one). Where the contract does not declare it, the 2026-08-10 hand mapping was carried
  forward and every operationId re-verified to still exist. Anything left over is recorded as mcp_only
  or rest_only rather than guessed.
