The Agentic API Grader by SaaStr.ai scores how API-ready any B2B product is from an AI agent's perspective. It evaluates APIs on 6 criteria critical for agent deployment—API design, webhooks, authentication, rate limits, SDKs, and overall agent readiness—across 100+ B2B APIs already loaded. Built by Jason Lemkin, it's a diagnostic tool for B2B teams to benchmark their software against what AI agents actually need to do their jobs.
