Monetize Any API in Seconds.

Paste an endpoint, choose a price, and your API becomes pay-per-call. Clients receive a 402 payment challenge, pay with HBAR or USDC over x402, and the gateway securely proxies the response while recording every settlement on Hedera Consensus Service.

how it works

The steps to get your paid URL

Connect your wallet

Sign in and an embedded Hedera account is provisioned for you automatically — no extension, no seed phrase to juggle.

Paste a URL, set a price

Point at any endpoint you own, price it in HBAR or USDC, and the gateway wraps it behind an x402 paywall in seconds.

Share the link, get paid

Agents and humans hit your link, pay the 402 challenge, and funds land in your account with every access logged to HCS.

live example

A full 402 handshake, end to end

Every unpaid request gets a signed 402 challenge. The client pays over x402, the facilitator settles on Hedera, and the response streams back with a receipt and an HCS sequence number you can verify on HashScan.
