# API Documentation - Nopaque

Developer documentation for the Nopaque REST API. Covers authentication with workspace-scoped API keys, the mapping, testing, load testing and compliance endpoints, and the Python and Node SDKs. The machine-readable OpenAPI 3.1 document is published in both JSON and YAML.

## Highlights

- OpenAPI 3.1 specification published at api.nopaque.co.uk in JSON and YAML
- Authentication via a workspace API key in the x-api-key header
- Every plan including Free can create an API key in the web app; an AI agent with no account can register its own workspace and key through the MCP server
- Official Python and Node SDKs, both open source
- An MCP server exposes the same capabilities to AI agents, plus registerWorkspace, requestAnchorCode, verifyAnchorCode and getClaimLink for an agent starting with no account
