Install a published client to send claims and check receipts. The Python and TypeScript SDKs work in your application; the CLI works from a terminal; the MCP server exposes QED Proof tools to an MCP client.

Python SDK

Submit claims, wait for verdicts, and verify receipts from Python 3.11 or later.

TypeScript SDK

Use Node.js 18 or later, Deno, or a browser to submit claims and verify receipts.

CLI

Submit and inspect claims, watch for verdicts, and verify a receipt from your terminal.

MCP server

Connect an MCP client over local stdio or the hosted Streamable HTTP endpoint.
You can also call the HTTP API directly. For a first end-to-end request, follow the quickstart.
