Built for integration

HTTP API

Create tasks, poll results, and check balance over a stable JSON API. Authenticate with your API key or JWT from the portal.

Client portal

Sign in with your username and password to view usage, logs, and documentation snippets. Rotate your API key when needed.

Transparent usage

Billing follows a clear per-task formula. Your dashboard shows balance, concurrency, and solve history.

Start free. Upgrade when the traffic is real.

Every new account can start without an invite. Capacity can then grow with paid, profitable usage, while purchased capacity remains your permanent floor.
