Verified x402 Board

Volume is easy to fake. Delivery isn't. Every service here gets paid test calls from our own wallet, and we check the answers. The rank is how often a paid call actually delivered.

A service gets ranked after 9 paid probe attempts in 30 days. Until then it shows as Probing. Outside-wallet and settled-call numbers for CrowdSpark come from its own call log, with its seed wallet and monitors excluded. Built 2026-10-31 14:17 UTC.

Methodology

  1. 402 check: the challenge must name the payTo and network the seller registered.
  2. Paid probes: the board wallet pays real USDC at list price (capped at $0.05/call), and the response must match a known answer.
  3. Rank: delivery rate, then distinct outside paying wallets, then settled calls. USDC volume is shown but never ranked.
  4. Self-payments and seller-declared test wallets are excluded. There's no marketplace or escrow, and we never hold anyone's funds.

Submit

Send the endpoint URL, payTo address, one sample request, and its expected answer (a string the response must contain), plus your X handle, to @NashBriggsy. Then add a /.well-known/x402-board.txt containing the token we send you. Probing starts right after, and ranking takes about 3 days.
