Gumloop

Use Gumloop's Call API node to run TokenMix models in your automation

What it is

Gumloop is a no-code AI automation platform where you drag and connect nodes on a visual canvas to build AI agents and end-to-end workflows. It was founded in 2023 and went through Y Combinator.

Before you begin

• A Gumloop account.
• A TokenMix account and an API key from tokenmix.ai/dashboard/keys (sk-tm-...).
• The endpoint https://api.tokenmix.ai/v1/chat/completions.

Gumloop's built-in AI nodes support a fixed list of providers and don't accept a custom base URL on standard plans. To use TokenMix, use the generic Call API node.

Connect TokenMix

1. In your flow, add a Call API node (under the advanced nodes).
2. Set Method to POST and URL to https://api.tokenmix.ai/v1/chat/completions.
3. Add headers: Authorization = Bearer sk-tm-... and Content-Type = application/json.
4. Set the JSON body, for example: {"model":"deepseek-v4-pro","messages":[{"role":"user","content":"..."}]}
5. Parse the response and pass choices[0].message.content to the next node.

Verify it works

Run the flow once. A response with a choices array means the call reached TokenMix. Confirm the spend in your TokenMix dashboard under usage.

FAQ

Why not a built-in AI node? Gumloop's native bring-your-own-key supports a fixed provider list, and routing AI through a custom endpoint is an Enterprise-only feature. The Call API node works on any plan.

Which model should I use? For high-volume flows, a low-cost model like deepseek-v4-flash or gemini-3-flash-preview; for harder reasoning, claude-sonnet-4.6 or gpt-5.5.
