Example use cases
Vetting an x402 seller before paying
“Before I let my agent start paying this x402 API, pull the seller report export from Infoharmoni Atlas so I can see how many real payers they've had in the last 30 days and whether the wallet concentration looks healthy.”
Tracking agent spend across x402 market
“Export the agent spend report from Infoharmoni Atlas — I want to know which of my agent's wallet addresses are paying the most across x402 sellers on Base and what the total USDC outflow looks like.”
Daily x402 market snapshot for research
“Grab today's daily file export from Infoharmoni Atlas so I can analyze which x402 seller categories are growing fastest and how USDC volume is distributed across the Base ecosystem right now.”

Endpoint
GEThttps://ausrine-who.onrender.com/x402/export/%7Bname%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, tabular market intelligence about the x402 API ecosystem on Base — specifically seller activity, agent wallet spend, payer concentration, or daily snapshots — in a machine-readable CSV format. Prefer it over the single-seller report card endpoint when you want a full-market view rather than a single seller's details, and over the Atlas Pro sellers.csv when you need spend/agent/daily views rather than the full registry snapshot.
Side effects
- Unknown export name returns an error or empty response — caller must use a valid named export such as 'sellers', 'agent-spend', or 'daily'
- Stale data if the daily snapshot has not yet refreshed for the current day
- Payment not charged on refusals, but caller receives no data
- Network timeout on Render-hosted service under cold-start conditions
- CSV may contain self-reported fields that are unverified by on-chain data
