}Overview
Classifies a batch of rows in one request and blocks until every row is scored. For workloads too large to wait on, use the asynchronous batch flow instead. Single-row realtime prediction isPOST /v1/reflex/predict.Authorizations
Morph API key, passed as Authorization: Bearer sk-.... Create keys at https://www.morphllm.com/dashboard/api-keys.
Body
application/json
Up to 300 rows, each with a correlation id, its models, and its text.
Inline batch of rows classified on the realtime engine.
Up to 300 rows.

"model": ["guardrail", "jailbreak"],

Response
Per-row results.
Per-row results for an inline batch.
One entry per row. A completed row carries predictions (one per model) and prefill_tokens; a validation-failed row carries error instead.
