Full request URL	`https://www.bettertoken.ai/v1/chat/completions`
Model	`YOUR_MODEL_ID`

Requisitos previos

Crea una BetterToken API Key
Copia un ID de modelo desde la model plaza o desde el cuadro Setup de la Key
Prepara una terminal con curl, o Python 3 / Node.js

Instalación

curl
Python
JavaScript

curl no necesita SDK. Confirma que curl --version funcione en tu terminal.

python -m pip install openai

npm install openai

Configuración manual

curl

curl "https://www.bettertoken.ai/v1/chat/completions" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  --data '{
    "model": "YOUR_MODEL_ID",
    "messages": [
      {
        "role": "user",
        "content": "Hello"
      }
    ]
  }'

Python SDK

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://www.bettertoken.ai/v1",
)

response = client.chat.completions.create(
    model="YOUR_MODEL_ID",
    messages=[
        {"role": "user", "content": "Hello"},
    ],
)

print(response.choices[0].message.content)

JavaScript SDK

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "YOUR_API_KEY",
  baseURL: "https://www.bettertoken.ai/v1",
});

const response = await client.chat.completions.create({
  model: "YOUR_MODEL_ID",
  messages: [{ role: "user", content: "Hello" }],
});

console.log(response.choices[0].message.content);

Verificar la conexión

En el Playground de la derecha:

Introduce YOUR_API_KEY en Authorization.
Sustituye model por YOUR_MODEL_ID.
Edita messages y envía la solicitud.

El Playground ya usa la URL completa https://www.bettertoken.ai/v1/chat/completions. Una respuesta 200 que incluya la salida del modelo en choices[0].message.content confirma la conexión.

Cambiar de modelo

Sustituye YOUR_MODEL_ID por el ID de modelo completo de la model plaza o del cuadro Setup. No acortes el ID según su nombre visible.

Errores frecuentes

Error	Solución
`401`	Confirma `Authorization: Bearer YOUR_API_KEY` y vuelve a copiar la BetterToken API Key.
`404`	Las llamadas HTTP directas usan `https://www.bettertoken.ai/v1/chat/completions`; el `base_url` del SDK usa `https://www.bettertoken.ai/v1`.
Modelo no encontrado	Usa el ID de modelo completo de la model plaza o del cuadro Setup.
Solicitud no válida	Confirma que `messages` sea un array y que cada elemento tenga `role` y `content`.
