How It Works

From idea to Bitcoin in four simple steps

01

Build a Service

Create an x402-compatible service that solves a real problem. AI agents, utilities, data feeds—anything useful.

02

Register on stx402

Deploy your service to stx402.com. Set your price in sats. Your service goes live instantly.

03

Get Votes

Share your service with the community. The most useful, creative, and well-executed services rise to the top.

04

Win Bitcoin

Top 3 services each week win real Bitcoin. Paid directly to your wallet every Friday at 00:00 UTC.

What Wins

Services are judged on three criteria

Utility

Does it solve a real problem? Would people actually pay to use it?

Creativity

Is it novel? Does it push the boundaries of what's possible with x402?

Execution

Is it well-built? Does it work reliably? Is the UX polished?
