## 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-pdf-tagged-x402-service-rankings-1fef6b13
```

Example prompt: Can you pull the current x402 market index for PDF-tagged services and show me which ones have the most unique paying wallets over the last 30 days, along with their prices and call counts?

## When to prefer this

Use this endpoint when you need a ranked, real-traffic-validated list of x402 services specifically tagged 'pdf', scored by actual paying-wallet activity over 30 days. Prefer it over generic API directories when you want market signal (real payers, real calls) rather than self-reported listings, and when you need a verifiable snapshot receipt. Not appropriate for L402 services, non-x402 protocols, or discovering PDF conversion tools outside the agent economy.

## Known failure modes

- No services tagged 'pdf' currently indexed — returns empty services array with count 0
- Snapshot stale or hash mismatch — receipt may indicate an outdated scoring revision
- Worker cold-start latency — response delayed beyond typical fast profile
- Upstream x402scan data unavailable — index may reflect incomplete 30-day window
- HTTP 402 if USDC payment of $0.008 not successfully processed before request

## 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 filtered to the 'pdf' tag, each entry including service name, network chain ID, 30-day call count, price in USD, resource URL, and 30-day unique paying wallets. Also includes total matched service count, query metadata (ranking field, operator, limit), the route used, a generatedAt ISO timestamp, and a declarant field. The snapshot is accompanied by a receipt identifying the snapshot hash and scoring revision for verifiability.
