OpenAI Responses compatible

Responses

An OpenAI Responses compatible endpoint using input-based requests and streaming events. The gateway keeps no conversation state: fields such as previous_response_id and store are ignored, so send the full history in input for multi-turn conversations.

});

const response = await client.responses.create({
  model: "<MODEL_ID>",
  input: "Hello, HashBid",
});
console.log(response.output_text);

body, _ := json.Marshal(map[string]any{
  "model": "<MODEL_ID>",
  "input": "Hello, HashBid",
})
req, _ := http.NewRequest("POST",
  "https://hashbidx.ai/v1/responses", bytes.NewReader(body))
req.Header.Set("Authorization", "Bearer <YOUR_API_KEY>")
req.Header.Set("Content-Type", "application/json")

Rust

let response = reqwest::Client::new()
    .post("https://hashbidx.ai/v1/responses")
    .bearer_auth("<YOUR_API_KEY>")
    .json(&serde_json::json!({
        "model": "<MODEL_ID>", "input": "Hello, HashBid"
