Tools
| Tool | Description | Behaviour |
|---|---|---|
| ai_detector | Estimate whether text (or a web page's text) is AI-written using a trained classifier: about 78% accurate on a held-out benchmark (not a guarantee).

| cron_next | Validate a 5-field cron expression (lists, ranges, steps, JAN-DEC/SUN-SAT names, @daily/@hourly macros) and return its next 1-20 run times in any IANA time zone (DST-aware), as local ISO, UTC ISO and epoch seconds. Deterministic, no network. Price $0.0031 via x402. | Not declared |
