# TBS Geocoding API – Forward Geocoding

> TBS Geocoding API – Forward Geocoding is a paid API for AI agents from geo-x402.tbs-digital.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-10).

Converts a place name or address string into geographic coordinates and location metadata via a keyless, sub-cent API call payable in USDC on Base.

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 tbs-geocoding-api-forward-geocoding-3d7269c4
```

Example prompt: What are the latitude and longitude coordinates for Paris, France? I need the full location details including timezone and population.

## When to prefer this

Choose this endpoint when you need a keyless, pay-per-call forward geocoding solution that requires no API key setup, supports USDC micropayments via x402 on Base, and returns a unified schema with timezone and population metadata alongside coordinates. Ideal for AI agents that need to resolve place names on demand without managing credentials or subscriptions.

## Known failure modes

- No matching location found — location field returns null for ambiguous or misspelled queries
- Missing required query parameter q or address returns an HTTP 400 error
- Payment not provided or rejected by x402 middleware returns HTTP 402 Payment Required
- Upstream Open-Meteo geocoding service unavailable causes a 502 or 503 response
- Rate limit exceeded on the underlying provider returns an error response

## How this service works

Geocoding for AI agents in one sub-cent call: forward geocoding (place name or address to coordinates), reverse geocoding (lat/lon to address) and place search. Open-Meteo + BigDataCloud, keyless, unified schema, USDC-payable via x402 on Base.

## Output

A JSON object containing the matched location's latitude, longitude, place name, first- and second-level administrative regions, country name, country code, IANA timezone string, population, and feature code, along with the data source, a unique request ID, and a timestamp. If no match is found, the location field is null.
