## 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 signaldesk-ai-month-days-lookup-f6ee752b -d '<json body>'
```

Example prompt: How many days are in February 2028?

## When to prefer this

Use this endpoint when you need a reliable, programmatic way to determine the number of days in a specific month and year — particularly when leap year correctness matters (e.g. February). Prefer this over local calendar logic when running in environments where date library access is limited or when consistency via an external API call is required.

## Known failure modes

- Invalid month (outside 1-12) returns an error response
- Invalid year (outside 0-9999) returns a validation error
- Missing required fields returns a 400 Bad Request
- Payment not attached or insufficient USDC triggers a 402 Payment Required response

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
