If you want your AI agent to use an API, here's the quickest safe way to set it up in Outloop.

First, check for a dedicated connector. If Outloop already has the right one, use it. If not, use Custom API.

Download the Custom API Skill — it's right here in Outloop, or on this page — and add it to Claude, Claude Code or Codex.

Then tell your agent which service you need. It asks, and I just say: Higgsfield.

The agent reads the provider's documentation and prepares the connection in Outloop for me.

When it needs a key, it offers to open Higgsfield's API page. I create the key myself, and I paste it straight into Outloop — once. It never goes into the chat, and the agent never sees it.

Then the agent finishes the setup, Outloop verifies the connection with a real request, and the agent runs a first real task.

And again — if a dedicated connector exists, use that instead.

The four steps are right below this video. Follow them to connect your next API.
