How to Use Unorouter API for Text Generation

Unorouter provides a simple, low‑cost API for generating text with advanced language models. This tutorial shows you how to call the API and integrate the response into your own applications.

Prerequisites

An API key from Unorouter (obtainable from your dashboard).
curl installed on your system (or any HTTP client).

Example Request

curl -X POST https://api.unorouter.com/v1/chat/completions \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "model": "gemini-3.6-flash:free", "messages": [ {"role": "user", "content": "Write a short story about a brave cat."} ], "temperature": 0.7, "max_tokens": 150 }'

Response

The API returns a JSON object:

{ "id": "chatcm_12345", "object": "chat.completion", "created": 1721234567, "model": "gemini-3.6-flash:free", "choices": [ { "message": { "role": "assistant", "content": "Once upon a time, a sleek cat named Luna..." }, "index": 0, "logprobs": null, "finish_reason": "stop" } ] }

Integrating the Response

Parse the JSON to extract choices[0].message.content. You can then display this text in your UI, store it, or further process it.

Tips for Better Results

Temperature: Lower values (0.2‑0.5) give more deterministic output; higher values (0.7‑1.0) increase creativity.
Max Tokens: Set a reasonable limit to control cost and response length.
Model Choice: Use the free tier (gemini-3.6-flash:free) for quick experiments; upgrade for higher quality.

Conclusion

Unorouter’s API makes text generation accessible with just a few lines of code. Experiment with prompts, models, and parameters to tailor outputs to your needs.
