}Private Endpoints
Create a private endpoint
Create a private endpoint as a draft. Drafts are not routable: validate one with POST /private-endpoints/{id}/validate, then activate it with POST /private-endpoints/{id}/activate. Pass activate to do all three in one call; if validation fails the draft is kept and returned with the failed checks. Send an Idempotency-Key header to make retries safe: a repeated key with the same request returns the endpoint the first request created; reusing it with different fields returns 422 idempotency_key_reused. Returns 400 parameters_invalid when tool_choice is declared without tools. The response does not echo declared_parameters or tested_parameters; read them with GET /private-endpoints/{id}. Management key required.

Retry-safe create: a repeated create with the same key from the same organization returns the endpoint the first request created instead of creating another. The endpoint is returned as it is now. Reusing a key with a different request body (model, provider, base URL, upstream model ID, declared ZDR or region, pricing, or declared parameters) is rejected with 422 idempotency_key_reused. Declared parameters are compared as a set, so a retry that reorders or repeats a name replays the endpoint. activate and settings are not compared, and later edits to the endpoint do not affect the comparison. settings is still validated before the replay, so a retry with invalid settings returns 400 settings_invalid instead of the endpoint.
Required string length:
1 - 255Example:
"wayfair-gpt-4o-eastus-2026-09"
Body
application/json
Parameters the upstream supports beyond the tested ones. Replaces the earlier declaration; tested parameters stay. Order and repeated names are ignored, but the list holds at most as many entries as there are declarable parameters, repeats included. tool_choice requires tools to be tested or declared.
Maximum array length:
25A chat request parameter the endpoint accepts.
Available options:
temperature, top_p, top_k, min_p, top_a, frequency_penalty, presence_penalty, repetition_penalty, max_tokens, max_completion_tokens, logit_bias, logprobs, top_logprobs, prediction, seed, response_format, structured_outputs, stop, tools, tool_choice, parallel_tool_calls, reasoning, reasoning_effort, web_search_options, verbosity Example:
["temperature", "seed"]
