What it is and what it does

py-builder-signing-sdk is a Python client library for authenticating with Polymarket's builder API. It handles the generation of cryptographically signed HTTP headers required to authenticate builder requests, supporting two signing modes: local signing using API key credentials (key, secret, passphrase) or remote signing by delegating to an HTTP endpoint. The package wraps the signing logic so you pass an HTTP method, path, and body to a config object and receive ready-to-use signed headers.

The package depends on python-dotenv for environment configuration and requests for HTTP operations. It targets Python 3.9 and later and is distributed as a pure-Python wheel with low installation friction. Given its narrow focus on Polymarket integration and aging maintenance status, it's most useful for developers building applications that interact with Polymarket's builder API.

Use it for

  • Authenticate requests to Polymarket builder endpoints when building trading or market-making applications.
  • Delegate signing to a remote service for key management separation in production environments.
  • Generate signed headers for custom HTTP clients that need to call Polymarket builder APIs.
  • Integrate Polymarket builder authentication into Python-based trading bots or market data pipelines.
