## 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-bulk-deep-discovery-819f7995
```

Example prompt: Show me the top 100 x402 services tagged as bulk, ranked by number of paying wallets over the last 30 days, and include the snapshot hash so I can verify the scoring revision.

## When to prefer this

Choose this endpoint when you need ranked, usage-verified discovery of x402 pay-per-call services with real 30-day call and payer data — especially for bulk queries. Prefer it over generic API directories when you need cryptographically receipted snapshots and payer-wallet-based scoring specific to the x402 ecosystem.

## Known failure modes

- Invalid or unsupported query parameters return an error or empty result set
- Network timeout if the index snapshot is large or the worker is under load
- Stale data if the 30-day rolling window has not refreshed recently
- Payment failure (402) if the $0.02 USDC fee is not included or wallet has insufficient funds
- Empty results if no services match the specified tag or filter criteria

## 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 a count of matched services, the query parameters used, the route, total matched services, an array of ranked service objects (each with name, network, 30-day calls, price in USD, resource URL, and 30-day payer count), the declaredBy field, and a generatedAt ISO timestamp plus a snapshot hash and scoring revision receipt.
