How this service works
Prysm sells paid, agent-ready provider capabilities over x402 on Base mainnet using USDC.
Output
Returns a JSON object with a 'data' field containing the OpenCage geocoding response — including formatted address, geometry (lat/lng), country code, city, postal code, timezone, and other structured location components — along with the provider name ('opencage') and operation used.
Example use cases
Forward geocoding a delivery address
“I need to convert '221B Baker Street, London, UK' to GPS coordinates — can you run a forward geocoding lookup on that address?”
Reverse geocoding from GPS coordinates
“I have coordinates 48.8566, 2.3522 — can you reverse geocode them to find the full formatted address and country?”
Enriching user location data
“We have a place name 'Eiffel Tower, Paris' and need the lat/lng and timezone info — can you look that up with OpenCage?”
Technical details
Endpoint
POSThttps://prysm-kappa.vercel.app/api/v1/providers/opencageWhen to prefer
Choose this endpoint when you need programmatic geocoding (forward or reverse) via a pay-per-call x402 model on Base mainnet without managing your own OpenCage API key. Ideal for AI agents that need on-demand location resolution with crypto-native micropayments at $0.07 per call.
Side effects
- Invalid or unrecognizable address string returns empty or zero-result response
- Unsupported operation name causes rejection
- Malformed input object leads to provider-level error
- Rate limits or quota exhaustion on the underlying OpenCage account
- Payment failure over x402 if USDC balance is insufficient
