    # API versions

    Endpoints are versioned via path prefix: `/v1/` for company, market price, and order book; `/v2/` for company lookup, funding rounds, investors, company details, and comps.


    # Company IDs

    Companies have two ID formats: a **v1 company ID** (used in v1 endpoints) and a **v2 company ID** (used in v2 endpoints). Both v1 and v2 company responses include both in `caplightIds` for cross-referencing. Path params that accept company identifiers support either format, plus PitchBook ID and company domain where applicable.


    If you have a domain, a v1 company ID or a PitchBook ID and need the v2 company ID, call `GET /v2/companies` — it resolves up to 50 identifiers per request and covers companies added recently.


    # V2 Access & Permissions


    **Company access:** v2 company-scoped endpoints (funding rounds, investors, company details, and comps) enforce per-account access control. Your account may have (1) a whitelist of permitted companies, (2) an annual limit on distinct companies you can access, or both. Accessing the same company multiple times counts once toward the limit. The `/funding-rounds/updates` endpoint returns only rounds for companies you have access to.


    **Restricted fields:** Some accounts have field-level restrictions. When a field is restricted, it is omitted from the response and its name appears in `restricted.fields` on the funding round object. Restricted fields may include: `amounts`, `valuation`, `pps`, `participants`, `citations`. Check for a `restricted` object and handle omitted fields in your integration.


    # Widget Embed

    In addition to this API, Caplight also provides an embeddable widget for customers who would like an easy way of integrating Caplight Data into their platform. [See example](https://storage.googleapis.com/caplight-prod.appspot.com/images/embed-example-3.png). For inquiries, please contact us directly.
