## 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 2s-geocode-address-forward-geocoding-bdca7852
```

Example prompt: Can you geocode '1600 Amphitheatre Parkway, Mountain View, California' and give me its latitude, longitude, and formatted address — return the top 3 results?

## When to prefer this

Choose this endpoint when you need to forward-geocode a free-text address or place name into coordinates without managing API keys or monthly subscriptions. Ideal for AI agents operating on a pay-per-call basis using USDC on Base or Solana. Backed by OpenStreetMap/LocationIQ data. Prefer over raw Nominatim when you need a unified, metered, agent-friendly REST wrapper with structured JSON output.

## Known failure modes

- Query string too short (< 2 chars) — returns validation error
- No matching location found — returns empty items array with total null
- Invalid country code format (not 2 lowercase letters) — returns validation error
- Limit out of range (< 1 or > 10) — returns validation error
- Payment failure via x402 — 402 response before data is returned
- Upstream geocoding provider unavailable — service error response

## How this service works

Forward geocoding — free-text address or place name → latitude/longitude plus structured address components (houseNumber, road, suburb, city, county, state, postcode, country, countryCode). Query: q (2-500 chars), limit (1-10, default 5), country (optional 2-letter ISO 3166-1 bias). Underlying data is OpenStreetMap (ODbL). Sister: /api/geocode/reverse.

## Output

Returns an array of matching location objects, each with latitude, longitude, formatted address string, bounding box coordinates, address components (city, state, country, postcode, house number), location type/class, and an importance score. Also includes the upstream source/license info (OpenStreetMap/LocationIQ) and metadata about whether the result was cache-hit.
