Agent payments are easy to talk about and hard to see. So we built a page where you can watch them settle.

Every little walker on screen is one paid API call, read straight from the chain as it lands. It wears the logo of the seller it paid and hops into the gate for its price: a tenth of a cent, a cent, a dime, a dollar, more.

Two protocols, side by side:

x402 on @base: USDC payments to sellers listed in public x402 discovery.

MPP on @tempo: payments to the recipients MPP sellers name in their own 402 challenges.

Filter to either one, switch between the last hour and the last day, and tap any walker to see the payment and its transaction, so you can check it yourself.

Up top: payments per minute, USDC settled and distinct buyers. Along the bottom: every payment as it arrives, seller and price.

No login, no sample data, no estimates. If it's on screen, it settled.

A few things we cared about:

It shows everyone, not just us. One walker is a payment to Agent402. Every other one is someone else building on x402 and MPP, getting paid by agents that never made an account.

It runs as its own read-only service. No keys, no shared database, nothing in common with the Agent402 API. It reads public chain data and public seller listings, and that's all.

It's open source with the rest of Agent402.

Leave it open in a tab. It's oddly calming.

Thank you to @HeyResearch for a careful private review of how Agent402 signs x402 payments: a clear write-up, a reproduction, and a check of our change the same day. If you build on x402 or MPP, their research is worth a follow.

Building a retrying agent? A re-sent signed x402 payment with the same nonce, route and body is answered from its first answer, marked X-Replayed-Answer: 1, with no second settlement.

Every 402 here offers MPP as well.
