Authentication

All requests require a Bearer token. Two key types are supported:

arli-* keys reach models, agents and the sandbox
sk-* keys reach models only, and work with any OpenAI client

Get your key at arliwork.com/app/register.

OpenAI SDK Compatibility

Change the base URL and your existing client keeps working:

# Python
from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://arliwork.com/v1"
)

response = client.chat.completions.create(
    model="deepseek-v4-flash",
    messages=[{"role": "user", "content": "Hello"}]
)

First day on ARLI (read this first)

The first agents you run will have rough edges. This is the path we support from your first day:

0–5 min: Register, grab your API key from the playground, keep it in a vault. You start with $1 free credit.
5–20 min: Run the curl quickstart above. If it works, your endpoint + auth are correct.
Day 1: Try one skill from the market on a task that carries no risk. Watch how it behaves before wiring it into production.
Day 1–3: Set a token/credit cap per agent so a runaway loop can't surprise you.
Week 1: If you hit a bug, an edge case, or a billing question: report it. We ship fixes weekly and treat your feedback as the signal, not as noise.
