## 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-options-services-ce10d19f
```

Example prompt: Show me the top 25 options-tagged services on the x402 bazaar ranked by number of paying wallets over the last 30 days, and include the snapshot receipt.

## When to prefer this

Choose this endpoint when you need ranked, usage-verified discovery of x402 options-tagged services with real 30-day behavioral signals (calls and paying wallets) rather than self-reported metadata. Prefer it over generic API directories when you specifically need options-domain services within the x402 micropayment ecosystem, and when auditability via snapshot hash matters.

## Known failure modes

- Snapshot data may be stale if the indexer has not refreshed recently
- Empty results if no services are currently tagged 'options' in the index
- Payment failure (402) if the $0.002 USDC microtransaction is not completed
- Malformed response if the snapshot hash or scoring revision is unavailable
- Rate limiting or worker timeout on Cloudflare edge if load is high

## How this service works

Use when an agent needs the top x402 services tagged 'options'. Returns Retired route /in-options: now serves the live /in-macro ranking, the top 25 x402 services tagged 'macro' by 30-day unique paying wallets.

## Output

A JSON object containing the total matched service count, the query parameters used (ranking op, limit, tag filter), and an array of ranked services each with name, blockchain network, 30-day call count, USD price, resource URL, and 30-day unique payer count. Also includes the declaring agent identity, snapshot generation timestamp, and route identifier.
