Get Started

InertialAI is two products behind one API key:

• InertialAI-0.1 — the chat model for real-world data (sensor streams, metrics, markets, health signals), behind an OpenAI-compatible API.
• Chronicle — self-serve finetuning: train on your data from $5, with an automatic before/after eval and a private scale-to-zero endpoint.

This page gets you from "I have an email address" to "the model just read my sensor data".

1. Create an account

1. Visit app.inertialai.com and click Sign up.
2. Fill out the registration form (email, name, password) and accept the terms.
3. Enter the verification code sent to your email and click Verify email (check spam if it doesn't arrive).

You'll land in the dashboard, signed in. Every new account starts with $5 of free usage — enough to chat with the model at length, embed, forecast, and train a first Chronicle finetune.

2. Create an API key

The API authenticates with API keys (they look like iai_...) sent as an HTTP bearer token.

1. In the dashboard, open the API Keys tab.
2. Click Create API Key, give it a title, and click Create Key.
3. Copy the key immediately — it is shown only once.

Set it as an environment variable so clients pick it up automatically:

export INERTIALAI_API_KEY="iai_..."

Every request then carries it in the Authorization header:

Authorization: Bearer iai_...

• API base: https://inertialai.com/api/v1
• Payloads: JSON request/response bodies

3. Make your first request

InertialAI-0.1 is OpenAI-compatible, so the standard OpenAI Python client is all you need:

pip install openai

import os
from openai import OpenAI

client = OpenAI(
    base_url="https://inertialai.com/api/v1",
    api_key=os.environ["INERTIALAI_API_KEY"],
)

resp = client.chat.completions.create(
    model="inertialai-0.1",
    messages=[
        {
            "role": "user",
            "content": (
                "Hourly server CPU temps (C): 61, 62, 61, 63, 88, 91, 90. "
                "What happened, and should I worry?"
            ),
        }
    ],
)

print(resp.choices[0].message.content)
print(resp.usage)  # exact token counts = your exact cost basis

:::tip Cold starts The model scales to zero when idle, so the first request after an idle period can take up to ~5 minutes (measured). Send a 1-token warmup ping first if that matters to you — see the quickstart. :::

The same request as raw HTTP, if you want to see the wire shape:

curl -sS \
  -X POST "https://inertialai.com/api/v1/chat/completions" \
  -H "Authorization: Bearer ${INERTIALAI_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "inertialai-0.1",
    "messages": [
      {"role": "user", "content": "Readings: 61, 62, 88, 91. Normal or anomaly?"}
    ]
  }'

Troubleshooting the first call

Symptom	Meaning	Fix
First request hangs for minutes	Cold start — the GPU is spinning up and the engine is compiling	Expected after idle; keep client timeouts ≥ 360 s, or send a warmup ping
401 Unauthorized	Key missing or malformed	Header must be exactly Authorization: Bearer iai_...
403 Forbidden	Key invalid, revoked, or expired	Create a fresh key in API Keys
422 Validation Error	Body doesn't match the schema	Include model: "inertialai-0.1" and a messages array; compare against the Chat Completions reference
429 Too Many Requests	Sending too fast	Back off and retry; honor Retry-After
