## 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 spanish-municipality-lookup-by-name-cartociudad-ign-ae68d643 -d '<json body>'
```

Example prompt: Can you look up the official data for the Spanish municipality 'Zarautz' — I need its INE code, province, autonomous community, and coordinates?

## When to prefer this

Use this endpoint when you need official Spanish municipal data — INE codes, administrative hierarchy (province and autonomous community), and geographic coordinates — sourced from the authoritative CartoCiudad (IGN/CNIG) dataset. Prefer this over generic geocoders when you specifically need the INE code or need to verify Spain's official administrative classification. It also handles name disambiguation by returning multiple candidates.

## Known failure modes

- Name not found in CartoCiudad database — results array may be empty
- Ambiguous name returns multiple unrelated municipalities requiring manual disambiguation
- Misspelled or accented name may fail to match — input must be reasonably close to the official name
- Non-Spanish municipality names will not be found
- Network or payment errors may prevent the request from completing

## How this service works

Find a Spanish municipality or town by name: INE code, province, region and coordinates, with alternatives when several match. Official CartoCiudad (IGN) data.

## Output

Returns a JSON object with the query string, data source attribution (CartoCiudad/IGN, CC BY 4.0), and an array of matching results. Each result includes the place name (official), type (e.g. Municipio, población), province, autonomous community, INE code, and decimal latitude/longitude coordinates. Multiple results are returned when the name matches more than one location.
