How this service works
Momentum radar for the x402 seller ecosystem - which sellers are heating up, graded for wash-trade resistance. Reads the hourly on-chain leaderboard (real Base USDC settlements) and adds per-seller signals the raw board doesn't have: organicScore (uniqueBuyers/callsSettled - 1000 calls from 2 buyers smells like self-dealing, 1000 from 400 is organic demand) and avgTicketUsd.
Output
A ranked list of up to 50 x402 sellers with per-seller signals including USDC settlement volume, raw call counts, organicScore (buyer diversity metric), and distinct paying wallet count — sourced from the hourly on-chain Base USDC leaderboard. The sort order and inclusion filter reflect the query parameters supplied.
Example use cases
Example prompt
“Show me the top 20 trending x402 sellers right now, ranked by organic score to filter out wash trades, and exclude Agent402's own wallet from the results.”
Technical details
Endpoint
GEThttps://agent402.tools/api/x402-trendingWhen to prefer
Use this endpoint when you need a wash-trade-resistant, multi-signal view of x402 seller momentum rather than raw settlement totals. It is the right choice when you need organic buyer diversity scoring, want to exclude internal wallets, or need to sort by distinct paying wallets rather than raw volume. Prefer this over generic blockchain explorers when you want pre-processed, agent-ready leaderboard data for the x402 seller ecosystem specifically.
Side effects
- limit out of range (1-50) returns validation error
- invalid sort enum value returns 400 bad request
- on-chain data may lag up to one hour if leaderboard hasn't refreshed
- no sellers returned if ecosystem has zero activity in the window
- payment failure (402) if USDC balance is insufficient
