How this service works
Real x402 demand from the chain: USDC an address (e.g. a seller's payTo) received on Base in the last 24 hours, with payment count, distinct payers, total, and top payers with the largest payer's share (a high share suggests self-testing or wash volume). Input: 0x address. Deterministic, no LLM.
Output
A JSON object containing the queried address, network identifier (eip155:8453 for Base), total USDC received in the last 24 hours, number of individual payment transactions, count of distinct payer addresses, an array of top payers with their USDC amounts, and the largest payer's share of total volume as a ratio (values near 1.0 indicate concentration risk such as self-testing or wash volume).
Example use cases
Vetting an x402 seller before paying
“Before my agent pays this x402 seller at 0xB3cDDccEe6B150c8efFD55B961afc0Ecefe7f247, can you check their actual on-chain revenue from the last 24 hours on Base and tell me if the demand looks real or if it's mostly one address paying them?”
Monitoring own revenue as a seller
“I'm running an x402 API and my payTo address is 0xB3cDDccEe6B150c8efFD55B961afc0Ecefe7f247 — can you show me how much USDC I've collected today, how many unique payers I've had, and who my biggest payer is?”
Detecting wash volume or self-testing
“Can you check if the x402 seller at 0x8F10B468b06c6FD214B65F87778827F7D113f996 is inflating their numbers — look at their top payer's share of total volume over the last 24 hours on Base and flag if it looks like self-testing?”
Technical details
Endpoint
POSThttps://minty-sprout.onrender.com/v1/x402-seller-revenue?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real, deterministic on-chain proof of x402 payment demand for a specific seller address on Base — not estimates or off-chain claims. It is the right choice when doing seller due diligence before paying an x402 API, auditing your own x402 revenue, or detecting anomalous payer concentration such as wash volume or self-testing. Prefer this over x402-preflight when you specifically need on-chain payment history rather than contract configuration facts.
Side effects
- Invalid or malformed 0x address returns an error or empty result
- Address with no x402 payments in the last 24 hours returns zero values
- Network congestion or RPC issues may cause delayed or incomplete on-chain reads
- Address not on Base network may return no results
- Rate limiting or payment failure if x402 micropayment of $0.003 USDC is not resolved
