About
API Report Card is a free tool from SaaStr.ai that grades any B2B API for how well it works in an agent-first world. It scores APIs across categories like authentication, error handling, documentation, pagination, idempotency, and overall agent-readiness, surfaces a letter grade from F to A+, and generates ready-to-paste prompts that developers can drop into Cursor, Claude, or Replit to fix the issues.
