## 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-finance-sector-84626fd0
```

Example prompt: Show me the top finance APIs currently available on the x402 marketplace, ranked by the number of unique paying wallets over the last 30 days.

## When to prefer this

Use this endpoint when you need a ranked, real-usage-validated list of live x402 finance services rather than a static directory. It is ideal when you want to identify which finance APIs have genuine traction (paying wallets, call counts) rather than just being listed. Prefer this over generic API directories when operating within the x402 micropayment ecosystem and you need provenance-verified, scored discovery results with snapshot receipts.

## Known failure modes

- No finance-tagged services indexed yet — returns empty services array with count 0
- Snapshot data may be stale if the indexer has not refreshed within the last 30 days
- Payment failure (402) if USDC payment header is missing or insufficient
- Worker cold-start latency on first request after idle period
- Upstream x402scan index unavailable — may return error or partial results

## 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 a ranked array of up to 25 finance-tagged x402 services, each with name, network chain ID, 30-day call count, price in USD, resource URL, and 30-day unique payer count. Also includes the total matched service count, query metadata, the route used, who declared the data, and a generation timestamp anchoring the snapshot.
