100 req/min per-token ceiling on Free, Unlimited, and Business tiers traps multi-team integrators, sync jobs, and AI-agent workloads, a single overactive Zapier/Make/n8n flow can burn the entire quota. Per-plan rate-limit gating forces customers onto Business Plus (1,000 req/min) or Enterprise (10,000 req/min) primarily to unlock programmatic headroom, not for feature value.

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.
