Upstreet DocsFull OpenAPI reference with interactive playground for the Upstreet platform.
REST API Reference
The Upstreet REST API gives you full programmatic access to every feature of the platform. All endpoints are documented from our OpenAPI 3.1 specification with an interactive playground -- you can try requests directly from these docs.

Using the SDK Instead
For most use cases, the pu-client SDK provides a more ergonomic interface than raw REST calls. The SDK wraps every API endpoint with typed methods, automatic authentication, and streaming support.
