Admin API rate limits (500/hr Free, 2,000/hr Plus/Advanced) are easily hit by scripts iterating across large libraries; raising limits requires Enterprise upgrade. Returns non-standard HTTP 420 (rather than 429) for rate-limit responses, which breaks naive client retry/backoff libraries. Full sourced list under Sources below.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
