## 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-pricing-tagged-services-6d94cac2
```

Example prompt: Show me the top 25 x402 services tagged 'pricing', ranked by 30-day unique paying wallets, with their call counts and prices — I want to see what's actually getting used in the agent economy right now.

## When to prefer this

Use this endpoint when you specifically need ranked discovery of x402 services in the 'pricing' category with real 30-day usage signals (calls and unique paying wallets). Prefer this over generic API directories when you need machine-verified demand metrics rather than self-reported listings, and when you are operating within the x402 / agent economy ecosystem on Base or EVM-compatible networks.

## Known failure modes

- No services tagged 'pricing' indexed yet — returns empty services array with count 0
- Snapshot stale if underlying x402 scan has not refreshed in 30-day window
- Network errors from Cloudflare Worker returning 5xx
- Malformed or missing tag filter returns unexpected result set
- Payment of 0.032 USDC not settled — 402 response blocking access

## 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 list of up to 25 x402 services tagged 'pricing', each with: service name, network (EVM chain ID), 30-day call count, price in USD, resource URL, and 30-day unique paying wallet count. Also includes query metadata (ranking field, operator, limit, tag filter), total matched services count, the route used, who declared the data, and a UTC generation timestamp for the snapshot.
