## 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 dayze-on-this-day-6a2d6cd7
```

Example prompt: Who are some famous people born on July 11? I want to know how many notable birthdays there are on that day and see their names.

## When to prefer this

Use this endpoint when you need to look up notable people born on a specific calendar day and month — especially for birthday-matching features, daily trivia, historical content generation, or personal CRM enrichment. It is preferable over general web search when you need structured, machine-readable output with person slugs for downstream lookups.

## Known failure modes

- Invalid or out-of-range day/month values may return an error or empty results
- Missing required query parameters (day, month) likely results in a 400 bad request
- Dates with no notable birthdays in the database return a count of 0 and an empty people array
- Rate limiting or payment failures (x402) may return a 402 or 429 status
