As of August 12, 2026, 1,571 unique provider domains publish resources payable over x402. The underlying catalog carries 15,217 raw listings, but listings are the wrong unit — one provider can publish hundreds of endpoints. Provider domains are the stable measure of how many independent services an agent can actually pay.
A public catalog of x402-payable resources exists, and its raw listing count is the number usually quoted. It is the wrong unit: a single provider can publish hundreds of endpoints, so listings measure how prolific the largest publishers are rather than how many independent services accept the standard. Listings also churn heavily as providers add and retire endpoints.
The defensible headline is unique provider domains — how many distinct operators an agent could actually pay. It is a much smaller number and a far more stable one, and it is what this page leads with.
The supply side of the payment rail
Transaction counts measure demand: agents paying. Provider counts measure supply: things worth paying for. A payment standard needs both, and the ratio between them is informative — a rail with heavy traffic across few providers is concentrated infrastructure, while one with many providers and thin traffic is early and unproven.
Also asked
Why is this number smaller than the x402 directory count I saw?
Directory counts are listings, not services. A single provider publishing hundreds of endpoints adds hundreds of listings but one provider. This page counts unique provider domains because that is what actually answers how many services an agent can pay.
