Rufe OpenAI-kompatible Chat Completions mit POST https://bettertoken.ai/v1/chat/completions auf. Die meisten external tools verwenden die Base URL https://bettertoken.ai/v1 und hängen /chat/completions selbst an.

Wichtige Einstellungen

Feld	Wert
API Key	BetterToken API Key
Full request URL	`https://bettertoken.ai/v1/chat/completions`
Model	`YOUR_MODEL_ID`

Voraussetzungen

Erstelle einen BetterToken API Key
Kopiere eine Model ID aus der model plaza oder dem Dialog Setup des Keys
Bereite ein Terminal mit curl oder Python 3 / Node.js vor

Installation

curl
Python
JavaScript

curl benötigt kein SDK. Stelle sicher, dass curl --version im Terminal funktioniert.

python -m pip install openai

npm install openai

Manuelle Konfiguration

curl

curl "https://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://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://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);

Verbindung prüfen

Im Playground auf der rechten Seite:

Trage YOUR_API_KEY unter Authorization ein.
Ersetze model durch YOUR_MODEL_ID.
Bearbeite messages und sende den Request.

Der Playground verwendet bereits die vollständige URL https://bettertoken.ai/v1/chat/completions. Eine 200-Antwort mit Modellausgabe in choices[0].message.content bestätigt die Verbindung.

Modell wechseln

Ersetze YOUR_MODEL_ID durch die vollständige Model ID aus der model plaza oder dem Dialog Setup. Kürze die Model ID nicht anhand ihres Anzeigenamens.

Häufige Fehler

Fehler	Lösung
`401`	Bestätige `Authorization: Bearer YOUR_API_KEY` und kopiere dann den BetterToken API Key erneut.
`404`	Direkte HTTP-Aufrufe verwenden `https://bettertoken.ai/v1/chat/completions`; SDK-`base_url` verwendet `https://bettertoken.ai/v1`.
Modell nicht gefunden	Verwende die vollständige Model ID aus der model plaza oder dem Dialog Setup.
Ungültiger Request	Stelle sicher, dass `messages` ein Array ist und jedes Element `role` und `content` enthält.

Technische Details

Base URL und vollständige Request-URL

Tools, die eine vollständige Request-URL erfordern, etwa GitHub Copilot und TRAE, verwenden https://bettertoken.ai/v1/chat/completions. Tools, die den Pfad selbst anhängen, etwa Cursor, Cline, OpenCode, n8n und Dify, verwenden nur https://bettertoken.ai/v1.
