# Cron Next 5-24 (5-Field Expression, UTC)

> Cron Next 5-24 (5-Field Expression, UTC) is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.007/call, status unknown (last checked 2026-09-29).

Computes the next 24 UTC trigger times for a given 5-field cron expression starting from a specified datetime.

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 cron-next-5-24-5-field-expression-utc-06762dd3 -d '<json body>'
```

Example prompt: What are the next 24 UTC times that the cron expression '0 9 * * 1-5' will fire, starting from 2025-06-01T00:00:00Z?

## When to prefer this

Use this endpoint when you need to reliably preview or audit the next 24 UTC execution times for a standard 5-field cron expression. It is ideal for pre-deployment schedule validation, monitoring setup, and automation planning where UTC-normalized output is required. Prefer the free sandbox endpoint (/v1/sandbox/cron-next-5-24) for testing before using this paid version.

## Known failure modes

- Invalid cron expression (malformed fields) — returns validation error
- 'from' datetime not in valid ISO 8601 format — returns parse error
- Expression has fewer or more than 5 fields — returns format error
- Payment of $0.007 USDC not provided or rejected — returns 402 Payment Required

## How this service works

Call when an agent needs the next 24 UTC times for a 5-field cron expression. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/cron-next-5-24 first.

## Output

Returns an ordered list of 24 UTC datetime strings representing the next scheduled trigger times for the provided 5-field cron expression, computed forward from the given 'from' datetime.
