x402 payments

You set the price per call

Your price

Charge per tool call in USDC on Base, Sepolia or Avalanche. Bouncer does not take a cut; callers pay the exact amount you configure, plus blockchain network fees.

Set on any agent

Enable x402 in an agent's Payments tab and set a price such as $0.01 per call.

Callers pay with USDC

The caller attaches an x402 payment header. The facilitator settles it on-chain and the receipt appears in your call log.

No platform markup

You keep the full amount. Network fees are paid by the caller to the chain, not to Bouncer.

Set up x402

sandbox included

Try paid calls without real money

The x402 sandbox facilitator at x402.org/facilitator lets you test end-to-end payment settlement before switching to production. Your call log shows the settled amount for every paid request.
