What the publisher says

From the Clervo Connect repository's README, as published. We do not edit it. Read it on GitHub

Clervo

Clervo lets software use AI models and agent tools with pay-per-use x402 payments, without managing separate provider accounts or API keys.

The public API is https://api.clervo.dev. Current products include AI, Web Search, Secure Sandbox, Prediction Intelligence, and Crypto Intelligence. Multi-chain RPC is not currently available through the public API.

Start

Make a free AI call:

curl -sS https://api.clervo.dev/v1/chat/completions \
  -H 'content-type: application/json' \
  -d '{"model":"clervo/laguna-s-2.1","messages":[{"role":"user","content":"Reply with ready."}],"max_completion_tokens":16}'

Connect Claude Code through MCP:

claude mcp add clervo -s user -- npx -y @clervo/mcp

Or choose another supported path at clervo.dev/start:

  • @clervo/sdk for TypeScript
  • clervo-sdk for Python
  • @clervo/mcp for Claude and other MCP clients
  • @clervo/router for the CLI and local OpenAI-compatible proxy
  • OpenAPI for direct HTTP

The hosted API supports OpenAI Chat Completions at POST /v1/chat/completions, OpenAI Responses at POST /v1/responses, Anthropic Messages at POST /v1/messages, and the native Clervo route at POST /v1/ai/execute.

Payment safety

Free operations require no wallet. Paid operations return HTTP 402 with the maximum price before execution. Clervo clients keep automatic payment off by default and support per-operation limits, daily limits, receipts, reconciliation, and same-key replay without a second payment.

Payment uses USDC on Base through x402 or MPP. If settlement is unknown, retry only after reconciliation; never create a new authorization just to recover an uncertain request.

Current products, model availability, routes, and prices are machine-readable:
