# MarketAi

> One OpenAI-compatible API for hundreds of AI models (chat and image), with prepaid credits.
> You pay only for successful requests.

Base URL: https://marketai.sassdesk.com/v1
Auth: header `Authorization: Bearer mk-...` (create keys in the dashboard: https://marketai.sassdesk.com/dashboard/keys)

## Endpoints
- GET https://marketai.sassdesk.com/v1/models: every model id with its price per million tokens (USD)
- POST https://marketai.sassdesk.com/v1/chat/completions: OpenAI chat format; `stream: true` for server-sent events
- POST https://marketai.sassdesk.com/v1/images/generations: {"model", "prompt"}, n=1, returns data[0].b64_json

## Notes
- Model ids look like `anthropic/claude-sonnet-4.5` or `google/gemini-3.5-flash`; list them first.
- Every response carries `usage.cost` (USD charged) and `marketai_request_id`.
- Errors use the OpenAI shape. 402 insufficient_credits: top up; 429: more than 60
  requests a minute on one key.

## Example (Python, openai SDK)
