How this service works
Convert addresses to coordinates or coordinates to addresses for $0.001 per request. No API key or subscription. Pay with USDC on Base via x402.
Output
Returns a JSON object with latitude (lat), longitude (lon), and a human-readable display_name string representing the resolved location (e.g. {"lat":42.36,"lon":-71.06,"display_name":"Boston, MA, USA"}).
Example use cases
Enrich delivery addresses with coordinates
“I have a list of delivery addresses and I need to map them — can you convert '221B Baker Street, London' to GPS coordinates so I can plot it?”
Reverse geocode a GPS ping
“I've got a GPS ping at 42.36 latitude and -71.06 longitude — what's the actual street address at that location?”
Locate business for mapping app
“I'm building a map of coffee shops and I need coordinates for 'Blue Bottle Coffee, 300 S Broadway, Los Angeles, CA' — can you look those up?”
Technical details
Endpoint
GEThttps://geocoding-x402.royaldemocracy.workers.dev/api/geocodeWhen to prefer
Choose this endpoint when you need lightweight, on-demand geocoding without managing API keys or subscriptions — ideal for AI agents that need pay-per-use access to geocoding via x402 and USDC on Base. Best for low-volume or bursty workloads where a flat per-call fee is preferable to a monthly subscription.
Side effects
- Address not found or ambiguous — may return empty or null result
- Invalid coordinate format for reverse geocoding — malformed lat/lon
- Payment failure via x402 — request rejected if USDC payment not completed
- Rate or quota limits on the underlying geocoding data source
- Network timeout from Cloudflare Workers edge node
