What Flux did, step by step
Flux split the ask into jobs and sent each one to the model or tool that fits it. It picks among vetted models for each kind of task, cost-aware.
Read the Stripe docsLive
Page reading
Flux read the current Stripe docs, so the code matches the API as it is today.
Write the integration with ClaudeLive
Model
Payment code is worth a frontier model, so Flux sent the writing there.
Second opinion on paymentsShipping
Second opinion
Money logic gets a second look. Flux checks the answer with another model and stops at a fixed cost cap.

The receipt
Every call comes back with the model or tool that ran it and what it cost, all on one bill.
These costs are illustrative, not a quote. flux-auto bills each model step at the Standard rate, or the Fast rate when it sends the step to the Fast lane and a Fast model answers. Never more than Standard. Pin a model and you pay its own rate. See pricing

Run it with your own agent
- Get your key.
- Connect Cursor to Flux with flux-auto as the model. Cursor setup
- Cursor sends only its chat and plan panel (Cmd/Ctrl+L) through Flux. Agent mode and Composer edits stay on Cursor's own backend, so to run every step of this job on Flux, use Claude Code or Codex.
- For page reading and images, add the Flux tools server to Cursor’s MCP settings as a remote HTTP server at
https://api.fluxrouter.ai/mcp-tools/, with your Flux key as the bearer token (Authorization: Bearer sk-flux-…). It offersweb_fetchto read a page andimage_generateto make an image. - Ask it for the job in your own words, like the ask at the top.

Questions
Does Cursor run every step here through Flux?
No. Cursor's chat and plan panel runs its model steps through Flux, but agent mode and Composer edits stay on Cursor's own backend. To run the whole job on Flux, including the edits, use Claude Code or Codex with the same key.
What does the second opinion check?
The answer your agent is about to act on. Flux checks it with other models first, and the check stops at a fixed cost cap, so it never runs away with your budget.
Does every step work on my key today?
Not yet. Second opinion is shipping to every account. Until then, ask your agent to check the payment logic with a second model. Apps on your own key are shipping. Until then, your agent can use its own tools for these steps, and Murage runs them today with apps built in. The steps marked Live work today.
What will it cost me?
The costs on this page are illustrative, not a quote. flux-auto bills each model step at the Standard rate, or the Fast rate when it sends the step to the Fast lane and a Fast model answers. Never more than Standard. Pin a model and you pay that model’s own rate instead. Web, image, voice and app steps have their own prices.
Anything to know about Cursor?
Only Cursor's chat and plan panel (Cmd/Ctrl+L) uses the custom endpoint. Composer, agent mode, inline edit, apply and tab autocomplete stay on Cursor's own backend.
