## 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-eoa-tagged-services-ranked-by-payers-8402b4bb
```

Example prompt: Show me the top EOA-tagged x402 services ranked by number of unique paying wallets over the last 30 days, including their call counts and prices.

## When to prefer this

Choose this endpoint when you specifically need EOA-tagged x402 services ranked by paying-wallet count, and you want a verifiable receipt (snapshot hash + scoring revision) for auditability. Prefer it over generic x402 market endpoints when your use case targets externally owned account activity rather than other agent protocol segments. Not appropriate for L402 listings, per-service MPP data, or cross-protocol aggregate totals.

## Known failure modes

- No services found matching the 'eoa' tag — returns empty services array with count 0
- Upstream x402 index temporarily unavailable — may return 5xx from Cloudflare Worker
- Stale snapshot if index has not refreshed within the 30-day window — generatedAt timestamp will reflect last successful run
- Malformed input parameters may be silently ignored due to loose schema validation

## 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 (or specified limit) x402 services tagged 'eoa', each with name, network, 30-day call count, price in USD, resource URL, and 30-day payer count; plus metadata including total matched count, query parameters, snapshot generation timestamp, and a receipt identifying the snapshot hash and scoring revision.
