The Messari AI API provides two services for programmatic access to AI-powered crypto intelligence:

Copilot

Real-time chat completions for contextual crypto responses. Supports OpenAI-compatible, Vercel AI SDK, and Messari native formats.

Deep Research

Asynchronous long-form research report generation on any crypto topic, backed by cited sources.

​
Authorization

Refer to our Authentication docs for creating an API key.

​
Pay-Per-Request with x402

No API key? Copilot chat completions are also available via x402 micropayments — pay per request with USDC on Base Mainnet, no account required. Deep Research is not currently available through x402.

Both services consume credits per request. Contact api@messari.io about enrolling in our consumption-based credit system.
