Run Kuro on your own API key: no Kuro credits, step by step

If you already pay Replicate, fal or Higgsfield for model runs, Kuro can run on that key. A generation your key pays for costs no Kuro credits: no hold, no charge, on any plan, including Free. You pay the vendor on your own bill, at their price, and the result lands in your Kuro library like anything else.

Your key, your bill. Kuro adds nothing on top.

Which keys work

Six media vendors: Replicate, fal, Higgsfield, Runware, Siray and Sunra. Add as many as you hold. Each one runs the models that vendor actually serves; Kuro knows which, request by request.

Add a key

1. Open Settings → Provider keys.
2. Pick the vendor, paste the key, save. It is stored encrypted and only ever sent to that vendor.
3. Make something. The price shown before you press reads 0 credits whenever your key is the one paying.

Who pays, request by request

Kuro checks whether one of your keys can run this exact request, not just this model. A vendor can serve a model and still decline one combination of inputs. With only a fal key, for example, a Seedance 2.5 take that carries a reference video runs on credits, because fal has no channel for that input; the same take without the video runs on your key.

One generation is paid by one payer. Kuro never splits a request across your key and credits, or across two of your keys.

Choose the order

If you hold more than one key, set the order under Settings → Agents, in “When an agent creates”: rank your keys and credits in one list. The first payer above credits that can run the request pays. A key ranked below credits is used only when you ask for it by name. With no list set, Kuro uses the first key you hold that can run the request.

That order is what an agent follows too: Claude, ChatGPT or Codex connected over MCP, an API token, a recipe run or a storyboard batch.

Your own Replicate models

A Replicate key can also carry models that are not in Kuro’s catalog: add any Replicate model to that key and it shows up for you alone, runs only on your key, and is never priced in credits.

What still counts

Your key pays for compute, not storage. On Free, the storage quota still applies to what you keep.

Try it

Add your key in Settings → Provider keys, then open /create and make one picture. If the price reads 0 credits, your key is paying.
