Endpoint
GEThttps://api.carbon-cashmere.de/v1/sponsor/model-retrainWhen to prefer
Choose this endpoint when you need a bespoke, professionally retrained crypto ML model with documented out-of-sample validation and a formal technical note, rather than using an off-the-shelf signal or pre-trained model. Suitable for institutional or sophisticated users willing to pay $2500 USDC for a custom deliverable with a defined SLA.

- Invalid or malformed properties input — 400 bad request
- Sponsor ID collision or duplicate submission — conflict error
