Sebar AI Test API docs

The API follows the OpenAI format (/v1/chat/completions, /v1/responses, /v1/models, embeddings, images) and the Anthropic format (/v1/messages). Any SDK or tool that lets you change the base URL works.

1. 1. Create an account — your first API key is ready in the dashboard.
2. 2. Top up credit from Billing.
3. 3. Point your SDK at the base URL below and use your key.

cURL

curl https://wltest.sebar.id/v1/chat/completions \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "claude-opus-5.5", "messages": [{"role": "user", "content": "Hello!"}]}'

Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(base_url="https://wltest.sebar.id/v1", api_key="YOUR_API_KEY")
stream = client.chat.completions.create(
    model="claude-opus-5.5",
    messages=[{"role": "user", "content": "Write a haiku about the sea."}],
    stream=True,
)
for chunk in stream:
    print(chunk.choices[0].delta.content or "", end="")

Node.js (OpenAI SDK)

import OpenAI from "openai";

const client = new OpenAI({ baseURL: "https://wltest.sebar.id/v1", apiKey: process.env.API_KEY });
const reply = await client.chat.completions.create({
  model: "claude-opus-5.5",
  messages: [{ role: "user", content: "Hello!" }],
});
console.log(reply.choices[0].message.content);

Anthropic SDK

import anthropic

client = anthropic.Anthropic(base_url="https://wltest.sebar.id", api_key="YOUR_API_KEY")
message = client.messages.create(
    model="claude-opus-5.5",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Hello!"}],
)
print(message.content[0].text)
