How we calculate this score

The Agent-Friendliness Score measures how well an API works when used by AI coding agents (Claude Code, Cursor, Copilot) rather than humans in browsers.

CLI Readiness (60%) scores 8 signals that matter for headless, automated use: official SDK availability, env var auth (no browser OAuth), headless compatibility, CLI tooling, JSON responses, curl examples in docs, rate limits, and machine-readable pricing. Each signal is weighted by how much it blocks or enables agent workflows.

Quality (40%) covers SDK maturity and maintenance: npm download volume, GitHub stars, release freshness, issue close rate, TypeScript support, docs quality, and breaking change frequency.

Docs Benchmark (where available) is sourced from Context7, which tests how well an LLM can answer practical questions using the library's documentation.

Coming soon: live agent benchmarks that measure tokens burned, success rate, and time to first working API call using real integration tasks.
