Performance-tier transaction caps, default Tier 1 allows only 100,000 API transactions/month, with overage billed in packs of 10 (~$0.15/pack on Tier 1); upgrading requires going through a CSM. Every create/update/delete/query counts as a transaction; batched creates don't share a transaction, making bulk loads expensive against the cap. 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.
