The x402 market, right now
Updated continuously from live probes — not a monthly snapshot.
Supply is growing fast, but only a small share of verified-live APIs show a real usage signal. The bottleneck isn't discovery anymore — it's knowing which APIs actually work. See how we measure this in our Methodology.

Methodology
How we measure these numbers
Numbers like "under 1%" deserve to be explained, not just asserted.
Verified-Live
An API where we've confirmed an actual HTTP 402 response with parseable payment requirements, via a health probe that succeeded within the last 7 days.
Usage Signal
Agent-originated traffic we can observe, excluding known bots and testing user agents. Calls made directly to a provider outside of Decixa are not counted, so real-world usage may be higher than shown.
Leaderboard Ranking
Currently ranked by a 7-day usage signal alone (provisional). We're introducing a composite "Decixa Score" — combining verification, uptime, and price stability — to make the ranking harder to game with raw call volume alone.
