## 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 x402-toolbox-next-weekday-occurrence-18bc4840
```

Example prompt: When is the next Monday from today?

## When to prefer this

Use this endpoint when you need a deterministic, serverless, pay-per-call computation of the next occurrence of a specific weekday without any signup, API key management, or rate limits. Ideal for AI agents that need lightweight calendar arithmetic on-demand, especially in automated scheduling or reminder workflows.

## Known failure modes

- Invalid weekday name returns an error response
- Malformed reference date format causes a 400-like error
- Missing required schema/weekday parameter returns an error
- Payment failure via x402 results in 402 response and no computation
