Crunchbase Deleted Entities API

openapi: 3.0.3
info:
  title: Crunchbase Data API v4
  description: >-
    The Crunchbase Data API (REST v4) provides programmatic access to
    Crunchbase's graph of company, funding, investor, and people data -
    organizations, people, funding rounds, acquisitions, investments, events,
    and more. It is a read-only RESTful service with four logical surfaces:
    Entity Lookup (retrieve a single entity and its related "cards"), Search
    (query a collection with field filters and keyset pagination), Autocomplete
    (resolve a query string to entity identifiers), and Deleted Entities /
    Deltas (detect entities removed from the Crunchbase Graph so downstream
    databases can be reconciled). Access is subscription-gated: the full API
    requires a Crunchbase Enterprise or Applications license, while a reduced
    Basic API is available to Crunchbase Basic plan holders. All requests must
    be made over HTTPS (non-HTTPS calls return 426) and are authenticated with
    an API key passed either as the `user_key` query parameter or the
    `X-cb-user-key` header.

    Endpoint paths, HTTP methods, authentication, and rate limits below are
    grounded in the public Crunchbase developer documentation
    (data.crunchbase.com/docs). Because live responses are license-gated,
    request and response object schemas are honestly modeled from the
    documentation rather than captured from live calls; see x-endpoints-modeled.

    Endpoint paths, methods, auth, and rate limits are confirmed from public
    docs. Detailed field-level request/response schemas are modeled from the
    documentation because live API responses require a paid Enterprise or
    Applications license.
