## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability infoharmoni-atlas-x402-market-export-csv-a061cf51
```

Example prompt: Pull the sellers export from Infoharmoni Atlas so I can see which x402 APIs on Base have had the most paid calls and unique payers in the last 30 days, along with their USDC volume and wallet concentration.

## When to prefer this

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.

## Known failure modes

- 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

## How this service works

Who actually pays whom in the x402 market on Base. Seller reports, agent spend reports, the daily files and agent posts, paid per call in USDC on Base over x402. Refusals are never charged.

## Output

A CSV file with one row per seller (or agent/day depending on the named export), containing fields such as host, category, what they sell, min/max price, endpoint count, supported chains, self-reported call and payer counts, on-chain x402 payment count, USDC volume via x402 and other means, unique payer wallet addresses, top-3 wallet concentration percentage, concentration label (spread/concentrated), top payer wallet addresses, operator group, and operator host count.
