# Crontab Generator API
[](https://crontab-generator.api.klymax402.com/mcp)
[](https://x402.org)
[](LICENSE)
Convert natural language like 'every Monday at 9am' into valid cron expressions with explanation and next run times. Pay-per-call via [x402](https://x402.org) (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Part of the [klymax402](https://klymax402.com) marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.
## Quickstart -- MCP
Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):
```json
{
"mcpServers": {
"crontab-generator": {
"url": "https://crontab-generator.api.klymax402.com/mcp"
}
}
}
```
## Quickstart -- HTTP (x402)
```bash
curl -X POST "https://crontab-generator.api.klymax402.com/api/generate" \
-H "Content-Type: application/json" \
-d '{"description":"..."}'
# -> 402 Payment Required, with an x402 payment challenge in the response body
```
Any x402-aware client ([`@x402/fetch`](https://www.npmjs.com/package/@x402/fetch), [`x402-agent-tools`](https://www.npmjs.com/package/x402-agent-tools), ATXP) handles the 402 -> sign -> retry cycle automatically.
## Tools
| Tool | Method | Path | Price | Description |
|---|---|---|---|---|
| `utility_generate_crontab` | POST | `/api/generate` | $0.003 | Generate a cron expression from natural language |
### `utility_generate_crontab`
Use this when you need to generate a cron expression from a natural language description like "every Monday at 9am" or "every 5 minutes". Returns the cron expression with validation.
**Parameters**
| Name | Type | Required | Description |
|---|---|---|---|
| `description` | string | yes | Natural language description of the schedule (e.g. 'every Monday at 9am', 'twice a day', 'every 5 minutes') |
Example response:
```json
{"expression":"0 9 * * 1","description":"Every Monday at 9:00 AM","nextRuns":["2026-04-14T09:00:00Z","2026-04-21T09:00:00Z"],"confidence":"high"}
```
**When to use**: creating new scheduled tasks from user instructions, building crontab configs from plain English, or translating business requirements into cron syntax. Use this BEFORE writing cron entries manually.
**Not for**: parsing existing cron expressions (use `schedule_parse_cron`), JSON validation (use `data_validate_json`), text analysis (use `text_count_words`).
