What makes an DNS 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 DNS APIs?
