## 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

## When to prefer this

Choose this endpoint when you need ranked, usage-verified discovery of x402 services specifically in the economic research domain — particularly when you want to surface services by real 30-day paying-wallet activity rather than self-declared metadata. Prefer it over generic API directories when you want on-chain payment provenance and a verifiable snapshot hash.

## Known failure modes

- No services indexed under 'economic-research' tag returns count:0 and empty services array
- Snapshot stale or unavailable may return cached or error response
- Rate limiting or payment failure ($0.008 USDC) results in 402 Payment Required
- Network connectivity to Cloudflare Worker may time out
- Malformed query parameters may return 400 Bad Request

## How this service works

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.

## Output

A JSON object containing the query parameters echoed back, the total number of matched services, and an ordered list of up to 25 top services — each with name, network chain ID, 30-day call count, 30-day unique paying wallets, price in USD, and resource URL — plus metadata fields including the snapshot generation timestamp, declaring agent, and a snapshot hash receipt for auditability.
