## 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 historical-events-by-date-lookup-40ae25ea -d '<json body>'
```

Example prompt: What notable historical events happened on November 5th? Give me a list with descriptions and sources I can use for a trivia post.

## When to prefer this

Use this endpoint when you need structured, attributed historical event data for a specific calendar date (month + day) — ideal for generating newsletter content, social media 'on this day' posts, or trivia questions. Prefer this over web scraping when you need reliable, licensed, and formatted historical facts with source links included.

## Known failure modes

- Invalid day (e.g. day=32) or month (e.g. month=13) returns an error or empty result
- Missing month or day parameter causes request failure
- No events found for obscure dates may return an empty list
- Payment failure (x402) if USDC balance is insufficient or payment not processed

## How this service works

Historical events lookup: pass any month and day and get back a list of notable things that happened on that date across different years, each with a short description and a source link. Refreshes as a reliable daily content source. Good for newsletter fillers, social media bots, and trivia-night question generators. Attribution included per license.

## Output

A list of notable historical events that occurred on the specified month and day across multiple years, each entry including a short description of the event and an attribution-compliant source link.
