summary: >-
  Windfall publishes NO first-party client library or SDK in any public package
  registry. The Windfall API is a single POST endpoint authenticated with one
  header, and the company's own Quickstart teaches it with raw cURL, `requests`
  (Python) and `fetch` (Node.js) — there is no `pip install windfall` or
  `npm i @windfall/...` step anywhere in the documentation. This is a recorded
  absence, checked against the registries, not an unchecked field. NO `SDKs`
  pointer is emitted in apis.yml, because there is no SDK to point at.

    Zero first-party results. The npm name `windfall` is held by an unrelated
    2012 "inheritance based CMS" (v0.0.0, published 2012-12-21,
    github.com/davidcameron/windfall) and the `@windfallswap/*` scope belongs to
    an unrelated 2020 DeFi protocol. Neither is Windfall Data, Inc.

    No CDN- or script-tag-distributed build exists. Windfall's own guidance is
    that the API must NOT be called from a browser (the token is org-scoped and
    the docs say never to expose it in client-side code), so there is no
    embeddable front-end bundle to version.

  note: >-
    The WindfallData GitHub organization exists and is public, but contains no
    client library for the Windfall API. Its public repositories are internal
    data-engineering utilities and forks of third-party projects — recorded here
    so a later round does not re-open this.
  repos:
  - name: 990_long
    language: Python
    pushed: '2017-12-10'
    kind: internal-tool
    note: Generates a long-form version of every field in the IRS 990 — nonprofit data tooling, not an API client.
  - name: beam-bigquery-utils
    language: Java
    pushed: '2025-11-13'
    kind: internal-tool
    note: Utilities for working with BigQuery in Apache Beam.
  - name: google-cloud-java
    language: Java
    pushed: '2022-04-18'
    kind: fork
    note: Fork of the Google Cloud Client Library for Java.
  - name: shap

    note: Fork of the SHAP model-explainability library.
  - name: redis-agent-memory-server
    pushed: '2026-08-12'
    kind: fork
    note: >-
      Self-described "Upstream Fork" of the Redis agent memory server. Actively
      pushed, and a signal that Windfall is building agent infrastructure
      internally, but it is not a Windfall API client and is not published to a
      registry.
documented_client_code:
  note: >-
    Windfall documents integration in three languages as inline snippets rather
    than as installable packages. These are copy-paste examples, not distributed
    artifacts, and are deliberately NOT recorded as packages.
  languages:
  - {language: shell, client: curl, source: 'https://api-docs.windfall.com/quickstart/'}
  - {language: python, client: requests, source: 'https://api-docs.windfall.com/quickstart/'}
  - {language: javascript, client: fetch, source: 'https://api-docs.windfall.com/quickstart/'}
