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.

Tools / Endpoints

Tool / RoutePriceDescription
search — POST /v1/search$0.005{query, max_results?} → [{title, url, snippet}]
search_enriched — POST /v1/search/enriched$0.02{query} → results + a Claude-generated, source-cited summary

Backends: SearXNG (JSON, if SEARXNG_URL configured) + DuckDuckGo (HTML) — free. Enrichment via Claude.

MCP

Streamable HTTP endpoint: https://foundrynet-search-production.up.railway.app/mcp

claude mcp add --transport http foundrynet-search https://foundrynet-search-production.up.railway.app/mcp

Tools list without auth (discoverable). Pass an fnet_ key as api_key (or Authorization: Bearer) to bypass payment; otherwise the tool returns an x402 payment_required object.

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.
