This reference describes the Serverless Inference REST API, which lets you call foundation models programmatically from your own applications. Use it to integrate hosted inference into services, scripts, or notebooks without managing model infrastructure.
This API calls models hosted by Serverless Inference. To manage Dedicated Inference gateways, deployments, and capacity claims, see the Dedicated Inference API reference. To compare Serverless Inference, Dedicated Inference, and Inference on CKS, see About CoreWeave Inference.
