Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

## When to prefer this

Use this endpoint when you need structured historical event data for a specific calendar date (month and day), especially for content pipelines like newsletters, trivia bots, or social media automation. Prefer this over general web search when you want concise, pre-structured on-this-day facts with article references rather than raw search results.

## Known failure modes

- Invalid day value (e.g. day > 31) returns an error
- Invalid month value (e.g. month > 12) returns an error
- Missing required parameters returns a validation error
- No events found for obscure dates may return an empty list
