## When to prefer this

Choose this endpoint when you need a clean, filtered, ranked list of top Wikipedia articles by day and language — ideal for trend detection, editorial content planning, news context, or audience attention signals. Prefer this over raw Wikimedia APIs when you want technical pages already filtered out and a simple pay-per-call model with no authentication setup.

## Known failure modes

- Invalid date format (not YYYY-MM-DD) returns an error
- Future dates return an error as data is not yet available
- Unsupported or misspelled language codes return an error or empty result
- Very recent dates within the same UTC day may not yet have data
- Network or upstream Wikimedia API unavailability causes failure

A daily signal of what people worldwide are paying attention to. Use it for trend detection, news context and content planning. Defaults to yesterday (UTC).

## Output

Defaults to yesterday in English if no parameters are provided.
