What it does
This server exposes independent measurements of x402 API sellers, including settlement data from blockchain, delivery verification, and accuracy grades against primary sources. It is for AI agents that need to evaluate payment safety and data quality before calling paid APIs.
- Call preflight(url) before paying an x402 endpoint to get a CLEAR/HOLD/ABORT verdict on payment safety and delivery history.
- Use find_api(task) to discover which payable API providers are proven accurate for a specific task, ranked by measured accuracy.
- Query most_accurate(category) to compare how close different sellers' returned values are to primary sources like exchange medians or on-chain data.

Before you enable it
An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
