# Proof API

> The Proof API lets any product embed the Proof of Thought editor, connect people's AI agents to it over MCP, and seal documents with a verifiable record of where their words came from: typed, shaped, AI or external, and whether a person was present.

Every page is also available as Markdown: add `.md` to its path, e.g. https://developer.proof.exalto.ai/quickstart.md. REST base URL: https://api.proof.exalto.ai/v1. Node SDK: @exalto/proof. Browser embed: @exalto/proof-embed.
