From idea to file

Illustrated workflow, not a recorded generation

You
Make three vertical ads for my coffee shop. Do not generate without my approval.

Agent
I check models and inputs, then call estimate_cost for each variant. I show the quoted total. Do you approve this cost?

You
I approve the quoted cost.

Agent
I call generate with confirm_token, wait for the results, download the files to the project and report their paths.

FAQ

Does the agent spend without asking?

Tell it to quote the entire project and wait for approval. MCP provides estimate_cost and confirm_token. Sharing a key does not replace instructions and a spending limit.

Do files stay in my project?

An agent with file access can download results locally. Ask it to save and verify each file: output URLs expire.
