## 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-perpetual-services-adb1cb2b
```

Example prompt: Show me the top 25 perpetual x402 services ranked by unique paying wallets over the last 30 days, including their prices and call counts.

## When to prefer this

Use this endpoint when you specifically need ranked discovery of x402 services tagged 'perpetual', sorted by real 30-day usage signals (calls and unique paying wallets) rather than self-reported metadata. Prefer this over generic x402 market indexes when your focus is perpetual-model services and you need auditable snapshot receipts to track ranking changes over time.

## Known failure modes

- No services indexed under the 'perpetual' tag returns an empty services array with count 0
- Snapshot index temporarily stale may return slightly outdated rankings
- Payment of $0.008 USDC required per call — missing or invalid payment header results in 402 response
- Service unavailable on Cloudflare Workers edge may return 5xx

## 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, the query parameters used (ranking operation, limit, tag filter), the total number of matched services, and an array of ranked service records each with name, network, 30-day calls, price in USD, resource URL, and 30-day unique payers. Also includes a declarant field, generated timestamp, and an implicit snapshot hash for audit/receipt purposes.
