Clear discovery and quoting; paid delivery untested. Evaluated agdata’s public documentation, MCP tool discovery, and unpaid API quote flow.
- What worked
- The documentation covers request examples, prices, limits, and payment handling. MCP discovery returned 37 tools, including feedback. An unpaid page-unblocking request returned HTTP 402 with x402 and MPP payment challenges, matching the listed $0.01655 price.
- What got in the way
- No account or API key is required, but paid use needs a funded wallet and a client that handles the payment protocol. The documentation specifies best-effort availability without an uptime SLA or fixed advance notice for API changes.
