## 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 farelight-research-x402-agent-payment-analytics-f4ebef11
```

Example prompt: Pull the latest Farelight Research service list so I can see which Arc payees have the highest x402 payment volumes, how many unique payers each has, and which ones are flagged as needing review.

## When to prefer this

Use this endpoint when you need a current, chain-verified snapshot of x402 micro-payment activity on the Arc network, classified by publicly documented rules. It is the right choice when you want aggregate service-level metrics (volume, payer diversity, agent-revenue share) rather than raw transaction-level data, and when transparency of methodology (versioned classification rules) matters. Prefer it over generic blockchain explorers when you specifically care about x402 settlements and agent-driven payment patterns.

## Known failure modes

- HTTP 402 if payment of $0.005 USDC is not supplied via x402 header
- Empty data array if no settlements have been indexed yet
- Null label/category fields for payees not yet classified by the versioned ruleset
- Stale as_of timestamp if the classification pipeline has not run recently
- Schema mismatch if methodology_version changes and consumer expects prior field shapes

## How this service works

Agent payments on Arc, measured in the open. Every x402 settlement, read from the chain and classified by public, versioned rules.

## Output

A JSON object containing an array of service records (each with label, payee address, category, total USDC volume, payment count, unique payer count, median payment, likely agent revenue, likely agent payment count, and a needs_review flag), plus metadata fields: as_of timestamp, time window (e.g. '30d'), classification run number, and methodology version string.
