FoundryNet Geo

x402-gated geocoding + distance gateway for AI agents. One call, one micropayment — 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 so agents on Smithery/Glama/Claude can call it directly.

Tools / Endpoints

Tool / Route	Price	Description
geocode — POST /v1/geocode	$0.005	Address → {lat, lng, formatted_address, components}, or {lat,lng} → reverse-geocode

Tools list without auth (discoverable). Pass an fnet_ key as the api_key argument (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, and a per-route 402 at GET /x402/{route} (with the PAYMENT-REQUIRED header). Validated on 402 Index.

For logistics, delivery, and real-estate agents that need geocoding at high frequency and low cost.
