## 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 agent402-uk-cron-next-fire-times-84c07e1d
```

Example prompt: What are the next 5 fire times for the cron expression '0 8 * * 1-5' in the Europe/London timezone?

## When to prefer this

Choose this endpoint when you need to preview, validate, or plan around a cron schedule — especially when timezone accuracy matters. Ideal for DevOps agents checking job schedules, automation pipelines that need to predict next run windows, or UIs that preview cron timings for users. Prefer over manual cron parsing when timezone conversion is needed alongside schedule computation.

## Known failure modes

- Invalid cron expression returns an error or empty list
- Unsupported IANA timezone string causes a 400-level error
- Count outside 1-50 range may be rejected or clamped
- Missing required 'expression' parameter causes a validation error
- Malformed query parameters return a schema validation failure

## How this service works

Don't burn tokens on deterministic work. Go/no-go jobs first: payout preflight, text firewall (PII/secrets), budget check — then rails, calendars, finmath. x402 USDC on Base. UK + global. agent402.co.uk — not agent402.tools. $0.001–$0.002 USDC on Base. No API keys.

## Output

Returns a list of up to 50 upcoming datetime strings representing when the cron expression will next trigger, expressed in the requested IANA timezone.
