## 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-in-status-ranked-discovery-a3f22948
```

Example prompt: Pull the current x402 Bazaar leaderboard for status-tagged services and show me the top 25 ranked by number of unique paying wallets over the last 30 days, including each service's price, call volume, and the snapshot receipt.

## When to prefer this

Choose this endpoint when you need a real-usage-validated, pay-per-call ranked discovery of x402 services specifically in the 'status' category, backed by actual 30-day call and payer data rather than self-reported listings. Prefer it over static registries or self-declared indexes when you need an auditable snapshot receipt (hash + scoring revision) for reproducibility, or when you are building agent routing logic that depends on market-signal rankings rather than alphabetical or manual curation.

## Known failure modes

- Payment not included or invalid USDC payment header — returns 402 Payment Required
- Worker cold-start or Cloudflare edge error — returns 5xx with no body
- No services matched the 'status' tag — returns count:0 with empty services array
- Stale index if underlying x402scan data has not refreshed — snapshot hash will reveal outdated generatedAt timestamp
- Malformed query parameters — returns 400 Bad 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 list of up to 25 x402 services tagged 'status', each with name, network chain ID, 30-day call count, price in USD, resource URL, and 30-day unique payer count; plus query metadata (ranking criterion, operator, limit, total matched services), a snapshot hash and scoring revision for auditability, a declaration source, and a generation timestamp.
