Windfall

aid: windfall
name: Windfall
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-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.

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.
