Frequently asked questions

What makes an Logging & Observability API "agent-friendly"?

For AI coding agents, the highest-impact signals are: an official SDK on npm or PyPI, environment variable authentication (no browser OAuth flow), JSON responses that parse cleanly, machine-readable pricing, and reasonable rate limits for scripted use. APIs missing more than two of these are painful for agents to use reliably.

How do you score Logging & Observability APIs?

Each API is rated on 8 signals worth 1-2 points each (11 raw, normalised to 10). The full rubric: official SDK (+2), env var auth (+2), headless compatible (+2), CLI tool (+1), JSON response (+1), curl/CLI docs examples (+1), reasonable rate limits (+1), machine-readable pricing (+1). The top-scoring API in this category right now is Datadog at null/10.
