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 a ranked list of an artist's most popular tracks sourced from Last.fm listener data. Prefer this over general music search when you specifically want play-count-ranked tracks for a known artist, especially when you need pagination for large result sets.

## Known failure modes

- Artist not found on Last.fm — returns empty or error response
- Misspelled artist name without autocorrect enabled — no results
- Page number exceeds available pages — empty results
- Rate limiting or payment failure — request rejected
- Limit value out of range (below 1 or above 100) — validation error
