  title: API Evangelist enhancements for the First Street Enterprise GraphQL API
  version: 1.0.0
extends: openapi/first-street-enterprise-api-openapi.yml
x-generated: '2026-09-10'
x-method: generated
x-source: >-
  Derived from https://docs.firststreet.org/api/enterprise-api/, the first-party SDL at
  graphql/first-street-enterprise-api.graphql, and a live anonymous introspection of the
  endpoint on 2026-09-10.
actions:
  - target: $.info
    update:
      x-apievangelist-enriched: '2026-09-10'
      x-graphql-sdl: graphql/first-street-enterprise-api.graphql
      x-graphql-introspection: open
      x-graphql-introspection-note: >-
        A full introspection query answered anonymously with HTTP 200 and 350 types on
        2026-09-10 — saved to graphql/first-street-enterprise-introspection.json. Data
        queries still require a key.
      x-mcp-server: null
      x-mcp-note: >-
        The Enterprise API has NO MCP surface. First Street's MCP server covers the Climate
        Risk API only; the docs state Enterprise expansion is planned.
      x-agent-skills: skills/first-street-portfolio-project.md
  - target: $.paths['/enterprise/graphql'].post
    update:
      x-response-semantics: >-
        HTTP 200 for every schema-valid request; failures in errors[] alongside data.
      x-async: job-and-poll
      x-async-note: >-
        Uploads, imports, exports, module refreshes and async deletes all return a
        ProjectJob whose status must be polled. No webhooks, no subscriptions.
      x-write-surface: true
      x-mutation-count: 42
      x-query-count: 25
      x-idempotency: none
      x-idempotency-note: >-
        No Idempotency-Key header, no request key, no documented replay window. A retried
        mutation is a second mutation.
      x-dry-run: false
      x-dry-run-note: >-
        The staged-assets step of the upload workflow is the only rehearsal available, and
        it covers one flow.
      x-reversibility: documented
      x-irreversible-operations: [deleteProjectAsync, deleteProject, deleteUserData]
      x-reversal-operations:
        - cancelProjectExport
        - setProjectStatus(ACTIVE)
        - deleteProjectAssetByPlaceID
      x-deprecated-schema-members: 42
      x-query-complexity-limit: 700
      x-rate-limit: 150 requests/minute (default, contractual)
  - target: $.components.securitySchemes.apiKeyQuery
    update:
      description: Static API key as the `key` query parameter. Long-lived and unscoped.
  - target: $.components.securitySchemes.bearerAuth
    update:
      description: 'The same static API key sent as `Authorization: Bearer <key>`. Not an OAuth token.'
