Assistants

The hosted API does not clone the OpenAI Assistants API. There are no /v1/assistants routes. Use /v1/responses when you need a stateful conversation primitive. The API stores response records for 24 hours and exposes retrieval routes:

Method	Path
`POST`	`/v1/responses`
`GET`	`/v1/responses/{id}`
`GET`	`/v1/responses/{id}/input_items`
`POST`	`/v1/responses/{id}/cancel`

Continue a response

{
  "model": "gpt-5.5",
  "previous_response_id": "resp_...",
  "input": [
    { "role": "user", "content": "Continue from the previous answer." }
  ]
}

Before the provider call, the gateway hydrates prior messages from the stored response chain.
