API

# Responses

The OpenAI Responses API at `/v1/responses`, for models whose `endpoints` list it. Requests are stateless: every turn carries its own input.

**On this page**

- [Request](https://inference.dagon.so/docs/responses#request)
- [Forwarded fields](https://inference.dagon.so/docs/responses#forwarded-fields)

## Request

POST `/v1/responses`

**curl**

```curl
curl https://inference.dagon.so/v1/responses \
  -H "Authorization: Bearer $DAGON_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "abliterated-model-large-flash", "input": "Summarise RFC 9110 in three lines.", "max_output_tokens": 512}'
```

**Python**

```python
import os
from openai import OpenAI

client = OpenAI(base_url="https://inference.dagon.so/v1", api_key=os.environ["DAGON_KEY"])

r = client.responses.create(
    model="abliterated-model-large-flash",
    input="Summarise RFC 9110 in three lines.",
    max_output_tokens=512,
)
print(r.output_text)
```

**TypeScript**

```ts
import OpenAI from "openai";

const client = new OpenAI({ baseURL: "https://inference.dagon.so/v1", apiKey: process.env.DAGON_KEY });

const r = await client.responses.create({
  model: "abliterated-model-large-flash",
  input: "Summarise RFC 9110 in three lines.",
  max_output_tokens: 512,
});
console.log(r.output_text);
```

## Forwarded fields

`model`, `input`, `instructions`, `max_output_tokens`, `stream`, `stream_options`, `temperature`, `top_p`, `top_logprobs`, `tools`, `tool_choice`, `parallel_tool_calls`, `max_tool_calls`, `text`, `reasoning`, `include`, `truncation`, `prompt_cache_key`, `store`, `metadata`, `user`, `safety_identifier`. Anything else non-null is `400 unsupported_parameter`.

- The output cap is `max_output_tokens` (default 16,384).
- Stored state cannot be priced, so `previous_response_id`, `conversation`, `prompt`, `background`, `item_reference` items and `file_id` parts are refused. Send the content inline.
- `tool_choice` may be `none`, `auto`, `required` or `{type: "function" | "custom", name}` naming one of the request's tools; hosted tool types and `allowed_tools` are refused.
- Images: `input_image` parts.
