From your app to an output

An idea. A request.
Something real.

Use a familiar API from your app or agent.
Synal connects it to the model you choose.

  1. 01

    Describe it.

    Choose a model. Send your text, image, or audio and the settings for the result.

  2. 02

    Approve the price.

    See the cost before you commit. Your client handles the request and payment.

  3. 03

    Make it yours.

    Use the result in your product. Video jobs finish asynchronously; check back for the clip.

How you pay

By the call.
From your wallet.

No Synal account, API key, or prepaid balance. Your app pays for the request it makes.

USDC is the payment currency. It’s a digital dollar token held in a wallet. Fund a compatible wallet, then authorize the quoted amount for a call.

x402 handles the exchange. The API returns a price. Your client signs a payment authorization and resends the request. Confirmed payments have an on-chain receipt.

A few things to know

Good questions.

Is Synal an app or an API?

Synal is an API for developers and agents. Use it to add model capabilities to your own product. Follow @synallabs for product updates.

Do I need to know crypto to use it?

You need a compatible wallet with USDC. Client libraries can handle the payment exchange; you choose the model, send the request, and approve spending. There is no Synal signup or prepaid account.

Are these real model outputs?

Yes. Showcase outputs were generated through Synal. Each sample identifies its model, generation time, and actual payment. They demonstrate individual runs, not guaranteed speed or results.

What happens if a request fails?

A confirmed failure before settlement is not charged. On some networks, and for async video jobs, the payment settles before the model runs; if the model then fails, a refund is owed. If payment is uncertain, check the existing payment before signing another.

Which networks can I use?

This release uses test USDC on supported test networks. Mainnet is not enabled in this release. The offered networks are shown with each quote.
