  title: API Evangelist enhancements for the First Street Climate Risk GraphQL API
  version: 1.0.0
extends: openapi/first-street-graphql-api-openapi.yml
x-generated: '2026-09-10'
x-method: generated
x-source: >-
  Derived from https://docs.firststreet.org/api/ and the first-party SDL at
  graphql/first-street-climate-risk-api.graphql. Captures what the transport-level OpenAPI
  cannot say: that this single POST is a door onto an 11-field GraphQL schema whose real
  contract lives in the SDL, and that responses are asynchronous.
actions:
  - target: $.info
    update:
      x-apievangelist-enriched: '2026-09-10'
      x-graphql-sdl: graphql/first-street-climate-risk-api.graphql
      x-graphql-introspection: gated
      x-graphql-introspection-note: >-
        POST {__schema{queryType{name}}} to this endpoint returns HTTP 401 Invalid API Key.
        The SDL is published instead at github.com/FirstStreet/api.
      x-mcp-server: https://mcp.firststreet.org/mcp
      x-agent-skills: skills/_index.yml
  - target: $.paths['/v3/graphql'].post
    update:
      x-response-semantics: >-
        Returns HTTP 200 for every schema-valid request. Failures appear in errors[] with a
        partially-resolved data object. HTTP 422 only for a malformed query.
      x-async: poll-on-status
      x-async-status-enum: [PENDING, RUNNING, SUCCESS, FAILED, TIMEOUT, ERROR]
      x-async-note: >-
        Every peril node carries status { name }. Read status before data; PENDING/RUNNING
        means the model is still computing for this place.
      x-entitlement: per-schema-node
      x-entitlement-error: 'Error 15: Your account has no access to this node.'
      x-query-complexity-limit: 700
      x-rate-limit: 150 requests/minute (default, contractual)
      x-rate-limit-headers: [x-ratelimit-limit, x-ratelimit-remaining, x-ratelimit-reset]
      x-idempotency: none
      x-data-vintage-default: latest
      x-data-vintage-retained: 2
      x-graphql-query-fields: [locality, localitiesByMacroeconomicConnection, localitiesByInsuranceConnection, place, placeByAddress, placeByCoordinate, assetTypes, metadataLookup, version, geospatial, adaptations]
      x-graphql-mutation-fields: []
  - target: $.components.securitySchemes.apiKeyQuery
    update:
      description: >-
        Static API key as the `key` query parameter. Long-lived and unscoped. Query-string
        keys land in logs and Referer headers — First Street's own docs require proxying
        browser-facing calls server-side.
  - target: $.components.securitySchemes.bearerAuth
    update:
      description: >-
        The same static API key sent as `Authorization: Bearer <key>`. The Bearer shape is
        borrowed; this is not an OAuth 2.0 access token. Preferred over the query parameter.
