## 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 x402scan-j55w7ornb-merit-systems-vercel-app-a9cb90be
```

Example prompt: Pull the last 30 days of on-chain x402 transactions for merchant address 0xf7b1356cfed0eebe01d76da7ba9e9f8bf12d9d57 on Base, sorted by amount descending, and show me the first 20 results.

## When to prefer this

Use this endpoint when you need to retrieve historical payment transactions received by a specific merchant address on x402-compatible networks (Base or Solana), especially when you need filtering by chain, timeframe, or sorting by time or amount. Prefer this over wallet-level endpoints when the target is specifically a merchant recipient address in the x402 ecosystem.

## Known failure modes

- Invalid merchant address format returns an error
- Unsupported chain value returns validation error
- Page size out of range (>100 or <1) returns validation error
- Timeframe value not in allowed set (1, 7, 14, 30) may return unexpected results
- Merchant address with no transaction history returns empty results
- Network timeout or Vercel cold start may cause latency spikes

## How this service works

Fetches on-chain transaction records for a specific merchant address, returning asset, amount, payTo, network and payment scheme details.

## Output

A paginated list of on-chain transaction records for the specified merchant address, each containing asset type, payment amount, payTo address, network (Base or Solana), and x402 payment scheme details.
