# Suverse Photon Reverse Geocoder

> Suverse Photon Reverse Geocoder is a paid API for AI agents from proxy.suverse.io, paid per call via x402, $0.08/call, status unknown (last checked 2026-09-14).

Converts a latitude/longitude coordinate pair to a structured address (street, house number, postcode, city, state, country) plus OSM IDs using Photon/OpenStreetMap, with no API key required.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability suverse-photon-reverse-geocoder-e8cb6550 -d '<json body>'
```

Example prompt: What's the street address at coordinates 48.8566° N, 2.3522° E? I need the full address including street, postcode, city, and country.

## When to prefer this

Choose this endpoint when you need a keyless, pay-per-use reverse geocoder backed by OpenStreetMap/Photon data, especially when you want to avoid managing API keys or subscriptions. It is ideal for agents that occasionally need coordinate-to-address lookups without committing to a geocoding platform contract. Prefer it over Google Maps or HERE Geocoding API when open data provenance (OSM) is acceptable and cost-per-call pricing is preferable.

## Known failure modes

- Coordinates in the middle of the ocean or uninhabited areas may return no address or only country-level data
- Malformed or out-of-range lat/lon values (e.g. latitude > 90) will cause a validation error
- OSM coverage gaps in rural or developing regions may produce incomplete address fields
- Payment failure (x402) if USDC balance is insufficient for the $0.08 per-call fee
- Rate limiting or service unavailability on the upstream Photon/OSM service

## How this service works

Reverse geocode a lat/lon to the nearest address via Photon (OpenStreetMap): street, house number, postcode, city, state, country and OSM ids. Keyless.

## Output

A structured address object containing street name, house number, postcode, city, state, and country fields, along with OpenStreetMap IDs (OSM node/way/relation IDs) for the nearest matched address to the input coordinates.
