## Services

- [adctx Payment Verification](https://www.zero.xyz/c/adctx-payment-verification-fbe3ee35/llms.txt): $0.05/call via x402. Checks whether a given Base blockchain address (x402 seller payTo) has actually received on-chain payments, classifying it as paid, single-payer, self-funded, dust-only, or silent, with payer counts and USDC received.
- [adctx Trace — Address Money-Flow Analyzer](https://www.zero.xyz/c/adctx-trace-address-money-flow-analyzer-72bc1b8f/llms.txt): $0.1/call via x402. Given any Base blockchain address, returns a breakdown of its USDC inflows by distinct payer, how many of those payers the address itself funded, the net USDC balance after removing self-funded returns, and stats on funded wallets that sent back the exact amount they received.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.
