Credits and Payments
Prompt improvement
What Improve prompt costs, when it charges, and how retries are handled.
Improve prompt in Create mode rewrites your prompt with more visual detail. It costs 1 Credit per suggestion.
How it charges
- The cost is shown and you confirm before anything runs.
- If your balance is below 1 Credit, the request is refused before it starts.
- You are charged only when a suggestion is returned. A failed request charges nothing.
- Repeating the same confirmed request, for example after a network error, is charged once and returns the same suggestion.
- Accepting or rejecting the suggestion doesn't change the charge.
Through the API and MCP
The improve_prompt action and POST endpoint follow the same rules. Send an Idempotency-Key so a retried request is charged once; the response includes chargedCredits. See the REST API Reference and MCP.
