  title: Windfall Windfall API API
  description: 'The Windfall API delivers enriched household and career data on a single-record basis in real time. Submit a person record with basic PII and receive enriched data about their household and career — all returned as JSON in a single request.


    Unlike batch enrichment jobs, the API returns results immediately, making it ideal for workflows that need data at the point of action.


    ## Common Use Cases


    - **Sales** — Real-time enrichment for lead routing and grading to inform immediate action.

    - **Marketing** — Enrich new leads as they''re created and enroll them in relevant nurture flows.

    - **Analytics** — Consume data in real time to power internal scoring and modeling efforts.


    ## Authentication


    All API requests require a valid token in the `X-WF-Auth-Token` header. Tokens are issued by Windfall and tied to your organization''s account. All requests must be made over HTTPS.


    > **Keep your token secure.** Never expose your API token in client-side code or public repositories.


    ## API Tokens


    Each token is issued with a set number of usage tokens that correspond to the number of records you can query. The token allocation and refresh frequency are determined by your purchase order.


    ## Rate Limits


    The API enforces a maximum of **5 requests per second**. Exceeding this limit returns a `429` status with a `rate_limit` error. Back off and retry after a brief delay.'
