The market at a glance

6514 indexed listings (paid 6503) across 632 seller wallets. x402scan sample: 4629.
Paid price distribution (USD): p25 $0.001 · median $0.0075 · p75 $0.02.

Demand is concentrated: a handful of endpoints absorb most calls, and the median paid listing sits at $0.0075 — the sweet spot for agent-payable APIs. Most listed endpoints are dead or unverified, which is why buyers increasingly check a service before paying.
