Loops API for coding agents

API docs

Loops has a small, legible API surface and unusually agent-friendly documentation. It belongs in the launch set even before its Agent Bench run because its published integration path is concrete and current.

Agent verdict

Can a coding agent use Loops? Yes, through the SDK or API.

Loops publishes llms.txt, agent-oriented guides, skills, and direct examples. The main setup dependency is a transactional template created and published in the dashboard before code can send it.

Clear agent guidance; dashboard setup required
