# Billing

Credits are charged when the task is submitted, based on the chosen provider's price for your parameters (per second of video, per image or per request). Failed or timed-out tasks are refunded automatically.

## Usage notes

- Chat models (GPT, Claude, Gemini, Grok, DeepSeek…) use the OpenAI Chat Completions format, so the official OpenAI SDKs work with base URL https://01router.com/api/v1. Set "stream": true for server-sent events. Credits for the prompt plus max_tokens (4,096 when unset) are held first, then settled to the real token usage once the reply ends; the same request id appears in the X-Gateway-Request-Id header and the task log.
- Same body as creating a generation. Returns every available provider sorted by price, plus the ones that cannot serve the request and why.
