## 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-ethereum-deep-leaderboard-6703094a
```

Example prompt: Show me the top Ethereum x402 services ranked by paying wallets over the last 30 days — I want to see which APIs are actually getting used and what they cost.

## When to prefer this

Choose this endpoint when you specifically need ranked, usage-verified discovery of x402 services in the Ethereum/EVM ecosystem, backed by real 30-day on-chain payment signals rather than self-reported metadata. Prefer it over generic API directories when you need to distinguish services with actual traction (paying wallets, call counts) from dormant listings. It is particularly valuable for competitive analysis, market research, or agent routing decisions within the x402 protocol ecosystem.

## Known failure modes

- No services match the ethereum tag — returns empty services array with count 0
- Snapshot index temporarily unavailable — returns 5xx or empty response
- Payment not processed — 402 response requiring USDC payment before data is returned
- Stale index — generatedAt timestamp may lag real-time by hours depending on indexing cadence
- Rate limiting or worker timeout on Cloudflare edge — returns 429 or 524

## 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 ranked array of x402 services tagged 'ethereum', each entry including service name, EVM network chain ID, 30-day call count, price in USD, resource URL, and unique payer count over 30 days. The response also includes the matched total count, the query parameters used, the route, a 'declaredBy' field, and a 'generatedAt' ISO timestamp with a snapshot hash and scoring revision for auditability.
