On embed, `input_type` is required beside `model`, and the reference says what each value is for, search_document when indexing and search_query when querying, so a model can pick cold. `embedding_types` and `truncate` are enums too, and 96 inputs a call is stated. On rerank, the reference says when to set `max_tokens_per_doc`, which matters because the default of 4,096 truncates long documents even on the 32K models. Errors are the thin part. The embed reference lists status codes 400 to 504 with no error bodies, the advice on what to change after a 400 is thin, and the 429 note says retry with backoff but names no Retry-After.
