## 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 timezone-toolkit-lookup-timezone-7942b654 -d '<json body>'
```

Example prompt: What's the IANA timezone for Delhi? I need to schedule a meeting with someone there and want the exact timezone string like 'Asia/Kolkata'.

## When to prefer this

Use this endpoint when you need to resolve a human-readable place name (city, region, or country) into a machine-usable IANA timezone string for scheduling, calendar logic, or display purposes. Prefer it over hardcoding timezone mappings or using a general geocoding API that does not return IANA identifiers directly.

## Known failure modes

- Query string is too ambiguous or misspelled — returns empty matches array
- City name is valid but shared across multiple countries — may return multiple matches requiring disambiguation
- Unsupported or very obscure location names may yield no results
- Network or payment failure (x402) — returns 402 Payment Required if USDC payment is not attached

## How this service works

Timezone converter, world clock, date math & meeting scheduler for AI agents. Pay-per-call x402 endpoints (USDC on Base).

## Output

Returns a list of timezone matches, each containing the country name and the canonical IANA timezone string (e.g. 'Asia/Kolkata') corresponding to the queried city, region, or country name.
