Async jobs

How a job runs.

Every model takes the same request and returns the same kind of job. Submit it, poll it, collect the file. The wallet pays for whichever model you picked.

Direct integration

What juggling three providers actually costs you.

Three accounts, three balances, three ways of saying a job is done.

Three wallets run dry on three different days.

Each provider bills you on its own. You top up three balances and learn which one hit zero when a job fails.

Three ways to sign a request.

Bearer tokens, signed JWTs, key pairs. Every provider wants its own.

Three ways to say a job is done.

One says succeed, one says SUCCESS, one returns a number. Your poller has to know them all.

Catalog

Every model, one catalog.

20 models from three providers across 7 task types. Each one has a page with its price, a request example and a playground.

FAQ

Before you integrate.

What is ScalingTensor?

ScalingTensor is an API marketplace for AI models. You call every model in the catalog through one HTTP/JSON API with a single API key, and pay per request from a prepaid wallet.

Where can I find available models and API pricing?

The model catalog lists every enabled model with its configured price per job, per second, per token or at the provider’s actual cost. Each model page also has a request example and a playground to try it before you integrate.

Can I use the OpenAI SDK?

Not directly. Media models use POST /api/media/generate and GET /api/media/result, and the chat endpoint is POST /api/chat/completion. All of them take an apiKey header and return code and data rather than the OpenAI SDK format, so an adapter is required.

How does pricing work?

Each model page shows how it is billed: per job, per second of audio or video, per output quantity, per token, or at the upstream provider’s actual cost. Charges are deducted from your prepaid wallet.

How do I create an account?

Sign up with Google or your email address on the sign-up page; email sign-ups confirm the address with a one-time code. You can then create API keys and top up your wallet.

Is my data secure?

All API traffic uses HTTPS, and requests are authenticated with API keys that you can revoke at any time in the console. Keep keys on your server, never in browser code. Generation requests are processed by the model’s provider, so review that provider’s data policy before sending sensitive content.
