How this service works
Utility API for AI agents — fetch URLs, extract structured HTML, summarize text, get live FX rates, and geocode addresses. Pay per call in USDC on Base or Solana via x402. No API keys, no subscriptions. Sub-cent pricing optimized for high-volume agent loops.
Output
Returns a JSON object with a timestamp, the original query string, a count of results, and an array of result objects each containing lat, lon, display_name, type, importance score, and bounding_box coordinates.
Example use cases
Geocode a delivery address
“I need the coordinates for '221B Baker Street, London, UK' so I can plot it on a map — can you look up the lat and lon for me?”
Resolve a city name to coordinates
“What are the latitude and longitude of Tokyo, Japan? I need the coordinates for a mapping calculation.”
Batch address enrichment for logistics
“I have this warehouse address — '500 West Madison Street, Chicago, IL 60661' — can you geocode it and give me back the lat, lon, and full display name?”
Technical details
Endpoint
GEThttps://hars.cryptotavern.xyz/paid/geocodeWhen to prefer
Choose this endpoint when you need pay-per-call geocoding with no API key or subscription, especially in high-volume agent loops where sub-cent USDC micropayments on Base or Solana are acceptable. It is well-suited for agents that only occasionally need geocoding and want to avoid managing API credentials. Use it when OSM Nominatim coverage is sufficient (global coverage, strong for cities and well-known addresses).
Side effects
- Address not found — results array is empty with count 0
- Ambiguous query returns multiple low-confidence results with varying importance scores
- OSM Nominatim rate limit or downtime causes upstream failure
- Malformed query string yields no parseable location
- Payment not processed via x402 — request rejected before geocode is attempted
