# ColdPegion

> ColdPegion is an AI-native cold outreach platform: autonomous email agents that write a unique email per prospect, MCP-native (drive it from Claude), and fully scriptable over a REST API. Yes, "Pegion" is spelled that way on purpose.

## API

- [REST API reference (markdown)](https://coldpegion.com/docs/api.md): the full v1 API in one document — auth, rate limits, every endpoint with parameters and examples
- [OpenAPI 3.1 spec (JSON)](https://coldpegion.com/api/v1/openapi.json): machine-readable schema of the same API
- [MCP server](https://coldpegion.com/api/mcp): authenticated Streamable HTTP endpoint for AI clients
- [Agent setup guide](https://coldpegion.com/agent-setup/prompt.md): client instructions, OAuth/token setup, connection checks and campaign review rules

- [Email verification](https://coldpegion.com/docs/email-verification): Use built-in checks, ZeroBounce or BillionVerify without confusing risk checks with mailbox proof.
