## 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 x402-bazaar-rank-in-base-deep-be2ace71
```

Example prompt: Show me the top x402 services on the Base network ranked by how many unique paying wallets they've had in the last 30 days, up to 100 results.

## When to prefer this

Use this endpoint when you specifically need to discover and rank x402-protocol services on the Base network by real economic activity (paying wallets and call volume) rather than self-reported metadata. It is the right choice over generic API directories when you want proof-of-usage signals — actual 30-day payer counts and call counts — rather than mere listings. Prefer it when you need a verifiable snapshot with a hash receipt for auditability of the scoring revision.

## Known failure modes

- No services match the Base tag filter — returns empty services array with count 0
- Snapshot index is stale or being rebuilt — may return outdated 30-day metrics
- Payment of $0.04 USDC not completed — 402 response blocking access
- Worker cold start or Cloudflare outage — 503 or timeout
- Malformed query properties parameter — may return unfiltered or error response

## 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: total matched service count, the query parameters used (by, op, limit, where/tag), the specific route, a list of ranked services each with name, network ID, 30-day call count, USD price, resource URL, and 30-day unique payer count, plus metadata including who declared the snapshot and when it was generated (ISO timestamp).
