How this service works
558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.
Output
A JSON object containing a ranked list of x402 services (resource URL, description, price in USDC, supported networks, 30-day call count, 30-day unique client count), plus ecosystem-level totals (services_in_bazaar, total_calls_30d, with_usage_30d), the data source label, and a timestamp for when the data was last updated.
Example use cases
Scouting popular agent APIs to integrate
“What are the top 5 most-called paid x402 APIs in the Bazaar this month? I want to see which ones real agents are actually buying so I can decide what to build next.”
Finding niche paid services by topic
“Search the x402 trending leaderboard for any paid services related to 'ERC20' — I want to see how many calls and unique clients they got in the last 30 days and what they cost.”
Benchmarking x402 ecosystem activity
“Give me the overall x402 Bazaar stats — total services listed, total calls in the last 30 days, and how many services have actual usage — plus the top 20 by call volume.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/x402-trending?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover which x402-paid services are genuinely popular by real usage data rather than self-reported listings — particularly useful for agents deciding which APIs to integrate, researchers benchmarking ecosystem growth, or builders wanting to find the most in-demand paid capabilities in the x402 Bazaar. Prefer this over static catalogs or directory listings when recency and actual payment/call volume matter.
