Create message (Anthropic format)
/anthropic/v1/messagesCreates a message using Anthropic Messages API format. Supports streaming via SSE.
Async inference: Send x-bf-async: true to submit the request as a background job and receive a job ID immediately. Poll with x-bf-async-id: <job-id> to retrieve the result. When the job is still processing, the response will have an empty content array. When completed, content will contain the full result. See Async Inference for details.
Header Parameters
Set to true to submit this request as an async job. Returns immediately with a job ID. Not compatible with streaming.
"true"Poll for results of a previously submitted async job by providing the job ID returned from the initial async request.
Override the default result TTL in seconds. Results expire after this duration from completion time.
