List a model response's input items

GET/v1/responses/{id}/input_items

List a model response's input items.

Compatible with OpenAI's list-input-items endpoint: returns the items that made up a stored response's input, as the provider lists them. Authenticate as for creating a response. Without x-retry-count a failed call is retried up to 3 times on 429 and 5xx.

Compatible with the OpenAI Responses API. The request and response bodies are the provider's own format, passed through by the gateway: see the OpenAI Responses API reference for every field. The credentials and headers below are what VectorAxis adds.

Authorization

AuthorizationBearer <slug>.<secret>
A virtual key's API key (vk-....<secret>), as Authorization: Bearer. What the OpenAI SDK sends from its api_key. Used by the inference endpoints.
orx-virtual-keyheader
A virtual key's API key in the x-virtual-key header, for clients that keep Authorization for something else.
orx-api-keyheader
Direct credentials: the provider's own API key in x-api-key, with the provider named in x-provider (for example openai). On /v1/messages a virtual key is accepted in x-api-key too, which is what the Claude SDK sends.

Path parameters

idstringrequired
the provider's response id, for example resp_...

Headers

x-providerstring
With direct credentials: the provider x-api-key belongs to, for example openai or anthropic (case and dashes are normalised). Not used with a virtual key.
x-retry-countinteger<int32>
How many times to retry a failed provider call, 0 to 5. Without the header, chat completions, Claude Messages and prompt completions do not retry, and the other endpoints retry up to 3 times. Retries back off exponentially from 1 second and honour a numeric Retry-After. The number made is in the x-retry-count response header.
x-retry-status-codesstring
Comma-separated provider status codes to retry on. Default 429,500,502,503,504,529.
