The gateway that picks the right model, checks the work, and proves it cost less.

Create a project

One project per app — its keys, spend and usage stay separate.

Your projects

Create an API key

One key per project and environment, named project/env. Then revoking a project stops that project — not the other nine. Grant only the scopes it needs, and give it an expiry.

Your keys

“Last used” is your early warning: a project that says never — or went quiet — is not reaching Atlantis and is likely falling back to another provider.

Upgrade

Checkout opens Stripe; after payment your license key is shown once on the success page — redeem it here.

Usage summary

Usage by app

Per-app breakdown from one key (via X-Client-App).

Point any OpenAI SDK at Atlantis

Use the key you created for this project. Sub-apps inside it name themselves with X-Client-App so usage still breaks down per app — see the Usage tab.

from openai import OpenAI

client = OpenAI(
    base_url="ORIGIN/v1",
    api_key="YOUR_PROJECT_KEY",         # the key named for this project/env
    default_headers={"X-Client-App": "my-app"},   # names this app in usage
)

r = client.chat.completions.create(
    model="auto",                       # or "coding:low", or any exact model
    messages=[{"role": "user", "content": "Hello Atlantis"}],
)
print(r.choices[0].message.content)

Check your wiring before you ship

A status code proves nothing — another service on a neighbouring port answers too, and a revoked key still gets a response. Assert on service, not on 2xx, or a wrong URL looks exactly like a working one.

import httpx

r = httpx.get("ORIGIN/v1/whoami", headers={"X-API-Key": "YOUR_PROJECT_KEY"})
r.raise_for_status()                    # wrong key -> 401, loudly
me = r.json()
assert me["service"] == "atlantis-engine"   # wrong host/port -> caught here
print(me["key_name"], me["scopes"], me["git_sha"])

Migrating from OpenRouter? X-Title / HTTP-Referer are honored too. Or use the outcome door for validated answers + receipts: POST /v1/execute {"goal": "..."}. Full reference at /docs.
