# AgentTools Country Database

> AgentTools Country Database is a paid API for AI agents from agenttools-hub.vercel.app, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Look up ISO 3166-1 codes, capitals, regions, population, area, currencies, languages, TLDs, and calling codes for any of 250 countries and territories — filtered by region or retrieved individually.

## 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 agenttools-country-database-04f5ab73
```

Example prompt: Look up the full country profile for Japan — I need its ISO code, capital, currency, calling code, TLD, and official language.

## When to prefer this

Choose this endpoint when you need standardized, structured reference data about countries — ISO codes, capitals, currencies, calling codes, TLDs, languages — and want a single consistent source covering all 250 ISO 3166-1 entries. It is especially useful for form validation, data enrichment pipelines, localization workflows, or regional filtering use cases. Prefer it over a general web search when you need machine-readable, structured output rather than prose descriptions.

## Known failure modes

- Invalid or unrecognized country name returns empty result or error
- Invalid region enum value may return a validation error
- Exceeding API rate limits may result in a 429 response
- Empty result set if region filter matches no countries (e.g., Antarctic with limit 0)
- Missing required 'input' field returns a 400 schema validation error

## How this service works

Reference database of all 250 countries and territories: ISO 3166-1 codes, capitals, regions, population, area, currencies, languages, TLDs and calling codes. Look up a single country or list by region. Use this when an agent needs to 250 countries: codes, capitals, currencies, populations.

## Output

A JSON object or array containing standardized country data including ISO 3166-1 alpha-2/alpha-3 codes, capital city, world region, population, land area, currency name and code, official language(s), country-code TLD, and international dialing/calling code. Single-country lookups return one record; region or list queries return an array of matching records up to the specified limit.
