Tracxn API is one of 2 APIs that [Tracxn](https://apis.io/providers/tracxn/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Companies, Investors, Funding Rounds, Acquisitions, and IPOs. The published artifact set on APIs.io includes API documentation, an API reference, and rate-limit docs.

Programmatic access to Tracxn's private-market database. Version 3.0 is current and version 2.2 is formally announced for deprecation. A uniform JSON-over-HTTPS contract: every data endpoint is a POST taking the same four-key body (filter, sort, from, size) with no path or query parameters, across companies, funding rounds, acquisitions, IPOs, investors, the two-level sector taxonomy (practice areas and feeds), eleven financial and employee time-series metrics, and four aggregation endpoints. Authenticates with an account-scoped token in the `accessToken` header; tokens are environment-specific and issued under Data Solutions > API & Developer Tools. `size` defaults to and maxes at 20, so pagination is mandatory, and billing is metered per entity returned. A free Playground environment scoped to the Cybersecurity feed is available for evaluation. Tracxn publishes no OpenAPI; the machine-readable contract is its official public Postman workspace.
