Example prompt: Can you pull up the full list of apps published by Apple App Store developer ID 284882215 so I can see their entire catalog?

## When to prefer this

Choose this endpoint when you need the full app portfolio for a specific Apple developer identified by their numeric developer ID. Ideal for competitive intelligence, M&A due diligence, publisher research, or discovering all titles from a known developer. Prefer this over app-specific lookup endpoints when the goal is breadth across a developer's catalog rather than deep metadata on a single app. The pay-per-call USDC model (no subscription required) makes it ideal for one-off or low-frequency lookups.

## Known failure modes

- Invalid or non-existent developer ID returns empty results or 404
- Developer has no published apps returns an empty catalog
- Payment failure (insufficient USDC balance) returns 402 Payment Required
- Rate limiting or Apple-side scraping blocks may cause transient failures
- Malformed developer ID format may return a validation error
