Built for payments.

Every request answers with a price, a signed payment settles it,
and the product ships only after the chain confirms.
Nothing moves early.

From launch to first request.

Three steps from a token to a paid response.

HTTP 402 → signed payment → result

  1. Create or connect

    Launch a new token on Pons, or verify one you already hold.

  2. Publish a paid product

    Choose what a request delivers and what it costs.

  3. Settle, then deliver

    A confirmed payment unlocks the response. Nothing ships early.

Before the first payment, try the flow.

Run a credit-based demo with a saved receipt. No real funds move.
