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.
