description: Windfall is an AI-powered people intelligence platform that helps go-to-market teams personalize
  workflows with wealth and career data, serving 1,500+ organizations across finance, retail, education,
  healthcare, and nonprofits. The Windfall API delivers enriched household and career data for a single
  person record in real time — submit basic PII and receive JSON in one HTTPS request. One operation (enrichRecord)
  returns up to 32 documented household fields (net worth and its confidence bounds, property, life events,
  philanthropy, political giving, financial signals) and 26 career fields (job title and level, job-change
  signals, employer firmographics, LinkedIn URL), with availability set by the customer's plan. US coverage
  only; the database is rebuilt weekly; rate limited to 5 requests/second; and a non-billed sandbox with
  15 deterministic fictitious personas and a header-driven error simulator mirrors production for integration
  testing. Access is contractual — tokens are issued by Windfall and API credits were bundled into existing
  subscriptions when the API opened to all customers and partners in May 2026.

  note: 'Corrected 2026-08-14. The prior pass recorded "self-serve signup", which the provider''s own
    documentation contradicts: tokens are issued by Windfall and tied to an organization account, quota
    and refresh cadence are set "per your purchase order", sandbox tokens are provisioned by an account
    representative, and API credits are bundled into an existing platform subscription. There is no sign-up
    form and no checkout — the docs are public, the credentials are not.'

x-tier: enriched
x-tier-reason: Entered as a portfolio lead, but Windfall publishes a real, parsing OpenAPI 3.1 description
  on its own docs host plus a nine-page reference (authentication, quickstart, endpoint, 32 household
  fields, 26 career fields, sandbox with an error simulator, examples, use cases). Two enrichment passes
  have been run against it.

    read the manifest and reported mcp_server correctly; the MCPServer type was crediting the artifact-type

x-pointers-deliberately-absent:
  note: Recorded so a later round does not re-open these. Each was probed on 2026-08-14 and is genuinely
    not published by Windfall; wiring the pointer would assert a surface the provider does not serve.
  absent:
  - type: SDKs
    reason: No first-party client library in any registry — packages/windfall-packages.yml, package_count
      0.
  - type: Idempotency
    reason: No Idempotency-Key header or equivalent is documented — conventions/windfall-conventions.yml.
  - type: StatusPage
    reason: status.windfall.com and status.windfalldata.com both 404.
  - type: Deprecation
    reason: No deprecation policy and no RFC 8594 Sunset/Deprecation headers.
  - type: ChangeLog
    reason: No dated changelog or release notes; /changelog 404s on both hosts.
  - type: Security
    reason: No vulnerability disclosure program, no security.txt on any host, no bug bounty.
  - type: WellKnown
    reason: Every /.well-known path 404s (or 401s behind the API gateway) on all four hosts — well-known/windfall-well-known.yml.
  - type: AgentCard
    reason: No A2A agent card at /.well-known/agent-card.json or /.well-known/agent.json on any host.
  - type: AsyncAPI
    reason: No event
    streaming or webhook surface exists — the API is a single synchronous request/response operation.: null
  - type: Webhooks
    reason: No webhook catalog is documented anywhere in the nine-page reference.
  - type: OAuthScopes
    reason: No OAuth 2.0 surface; authentication is a single static header token.
  - type: Pricing
    reason: https://www.windfall.com/pricing 404s and the 146-URL sitemap contains no pricing route.
  - type: SignUp
    reason: No self-service signup — API tokens are issued by Windfall against a purchase order.
  - type: Roadmap
    reason: No public roadmap.
  - type: CLI
    reason: No first-party command-line tool.
  - type: Protobuf
    reason: No gRPC or protobuf surface.
  - type: ToolCrosswalk
    reason: No MCP server and no GraphQL surface to crosswalk against the OpenAPI — mcp/windfall-mcp.yml
      deployment.mode is none.
