## 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 x402-bazaar-rank-retail-operations-discovery-181e8e81
```

Example prompt: Show me the top 25 retail operations services on the x402 market right now, ranked by paying wallets over the last 30 days — I want the live snapshot with call counts and prices.

## When to prefer this

Choose this endpoint when you need a ranked, real-usage-validated view of x402 services specifically in the retail operations vertical — not just a raw directory listing. It is superior to generic x402 service indexes when you want payer-weighted signal (not just self-declared metadata) and need a receipt hash to verify snapshot integrity. Prefer it over broader x402 market indexes when your agent's task is specifically scoped to retail, point-of-sale, inventory, or commerce automation use cases.

## Known failure modes

- No services indexed under retail-operations tag — returns empty services array with matched:0
- Snapshot index temporarily stale — generatedAt timestamp may lag real-time by minutes
- Network or worker cold-start latency — slow first response on infrequently called routes
- Malformed or missing query parameters — may return default ranking behavior without error signal
- Payment failure (insufficient USDC balance) — HTTP 402 returned before data is served

## How this service works

An open index of the machine-to-machine (agent) economy. x402 routes: ranked discovery over the live x402 service market, every indexed service scored by real 30-day calls and paying-wallet bounds, with a receipt naming the snapshot hash and scoring revision. /economy routes, for Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 agent registries, Solana agent registries, Base agent contracts and MCP servers (Official MCP Registry): each protocol's published figures (agent or server counts, transactions or payment events; payers and USD volume only where the source publishes them: payers for x402 and Tempo MPP, USD volume for x402 and Virtuals ACP), each with its unit, window and source; units differ, so totals are not summed. L402 and per-service MPP listings are not covered.

## Output

A JSON object containing the count of returned services (up to 25), the query parameters used (tag, operator, limit), the total matched service count across all indexed retail-operations services, an array of ranked service records each with name, network, 30-day call count, 30-day unique payer count, price in USD, and resource URL, plus a snapshot hash and scoring revision timestamp for auditability.
