FoundryNet Search
x402-gated web search gateway for AI agents. Structured results, or an AI-summarized sourced answer. No API keys, no accounts.
Part of the FoundryNet Data Network. Pay-per-call in USDC (x402) or bypass with an fnet_ Forge key. Also exposed as an MCP server for Smithery/Glama/Claude.

Payment (x402)
Standard x402 v2 on Solana mainnet USDC. Discovery: GET /x402, GET /.well-known/x402, per-route 402 at GET /x402/{route}. Validated on 402 Index.
Volume play — every agent needs web search, and $0.005/query is cheaper than most alternatives.
