# Cron Next Runs

> Cron Next Runs is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Evaluates a cron expression and returns the next 10 scheduled run times in UTC, a plain-English description, and the interval between runs

## Facts

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-runs-c615d12b
```

Example prompt: What are the next 10 run times for the cron expression '0 9 * * MON-FRI' — give me the UTC timestamps, a plain-English description of the schedule, and how often it runs?

## When to prefer this

Choose this endpoint when you need to quickly validate or preview a cron schedule before deploying, when you want a human-readable explanation of what a cron expression does, or when you need to compute precise future run times from a custom start time. It supports standard 5-field cron syntax including ranges, steps, lists, and named values (MON/JAN etc.), making it suitable for most Unix/Linux cron use cases.

## Known failure modes

- Invalid cron expression syntax returns an error
- Unsupported 6-field expressions (with seconds) may not parse correctly
- Malformed start time after pipe causes parsing failure
- Network timeout for the $0.01 x402 payment flow
- Empty or missing input query parameter returns an error

## How this service works

Cron expression evaluator: the next 10 run times in UTC for a standard 5-field expression (ranges, steps, lists, names like MON/JAN, */5), a plain-English description, and the interval between runs. Optional start time after a pipe. Validate schedules before deploying. $0.01 per expression.

## Output

Returns the next 10 UTC run timestamps for the given cron expression, a human-readable description of the schedule (e.g. 'Every weekday at 9:00 AM'), and the interval duration between consecutive runs. Optionally accepts a custom start time after a pipe character to compute runs relative to a specific point in time.
