Give your agents access to money
We just shipped a drop-in payment modal for any x402 paid endpoint.
The protocol is simple but the wallet UX is not.
This package is the missing front end to give everyone fair and equal access to agentic payments.
Pay in stablecoins (USDC) or
$THREE on Solana.
x402 lets any HTTP endpoint charge a micropayment per call: the server answers an unpaid request with 402 and a list of accepted payments; the client pays and retries with an X-PAYMENT header.
We shipped a single, framework-agnostic modal that handles wallet detection, chain switching, signing, settlement, errors, throttle retries, and the receipt, so you ship a paid endpoint in minutes.
Drop in a <script> tag or import it. The
@Solana crypto helpers are loaded lazily from a CDN only when a payment is actually attempted.
The modal picks the right path from the 402 challenge.
If a wallet already paid for a resource, it can sign back in instead of paying again.
Spending caps. Optional per-call / hourly / daily caps enforced in the browser.
Themeable. Light + automatic dark mode, all classes overridable.
Accessible. Focus management, aria-modal, keyboard Esc to close.
If you watched until the end and also read to the end, then you probably saw the pole club x402 demo. Yes, it is real. I am sure someone will link it under this post. We did something special for the entry to actually get into the club, you'll notice "banned?" in the entry x402 payment modal before entering the club. That's agent reputation. If your agent is acting up, it might just get banned from the pole club! Agent reputations matter. We made it easy to verify your environments are safe from toxic AI agents. Everything open source and ready to be added to your projects.
