## 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 p0-agent-economy-index-ip-tagged-x402-services-ranked-by-payers-3a76c462
```

Example prompt: Show me the top 25 IP-tagged x402 services right now, ranked by how many unique paying wallets used them over the last 30 days, so I can see which ones are actually getting real agent traffic.

## When to prefer this

Choose this endpoint when you specifically need to discover and rank x402 pay-per-call services in the IP category by real economic activity (unique paying wallets), rather than by self-reported metadata or static listings. Prefer it over generic service directories when you want ground-truth demand signals from actual micropayments on the x402 protocol.

## Known failure modes

- No services found matching the ip tag — returns empty services array
- Snapshot hash unavailable if index hasn't been updated recently
- Network or Cloudflare Worker downtime returns 5xx
- Malformed query parameters return 4xx
- Stale data if the 30-day window hasn't refreshed

## 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 count of matched services (up to the limit), the query parameters used, the route, the total number of matched services in the index, and an array of service objects each with name, network (EVM chain ID), 30-day call count, price in USD, resource URL, and 30-day unique paying wallet count. Also includes a 'declaredBy' field and a 'generatedAt' ISO timestamp marking the snapshot.
