## 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-fraud-tag-56f0c331
```

Example prompt: Pull the top 25 fraud-tagged services from the x402 Bazaar ranked by unique paying wallets over the last 30 days, and show me the snapshot hash so I can verify which scoring revision this came from.

## When to prefer this

Choose this endpoint when you specifically need to discover and rank x402-protocol services that carry the 'fraud' tag, backed by verifiable 30-day real usage signals (calls and unique paying wallets). Prefer it over generic API directories when you need cryptographically receipted snapshots of market activity, or when building compliance, competitive intelligence, or trust-scoring workflows around fraud-adjacent x402 services.

## Known failure modes

- No fraud-tagged services indexed yet — returns empty services array with count 0
- Snapshot hash unavailable if indexer is mid-refresh — may return stale generatedAt timestamp
- Invalid or malformed request parameters return a 400-level error
- Service index temporarily unavailable returns a 5xx error
- Rate limiting or payment failure (x402 payment required) returns 402

## 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 total matched count, the query parameters used (tag: fraud, ranked by payers), a list of up to 25 services each with name, network chain ID, 30-day call count, 30-day unique payer count, price in USD, and resource URL, plus metadata fields for the snapshot hash (declaredBy, generatedAt) and scoring revision receipt.
