## OpenAPI

````yaml nodeapi/openapi/admin-api.json GET /chains
openapi: 3.1.0
info:
  description: |-
    Programmatic, API-key-authenticated surface for managing
    Validation Cloud RPC endpoints and retrieving usage. Only the
    currently-implemented endpoints are documented; the broader PRD
    surface is intentionally omitted until served.

    `/admin/v1` is a strict contract — breaking changes are made
    under `/admin/v2`, never in place. Clients branch on the stable
    `error.code` enum, not on HTTP status alone.
