## 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-oracle-services-feed-9a223625
```

Example prompt: Show me the top oracle services on the x402 market right now, ranked by how many unique paying wallets they've had in the last 30 days, and include their prices and call counts.

## When to prefer this

Choose this endpoint when you need to discover and rank x402-protocol oracle services specifically, with verifiable usage metrics (real 30-day calls and unique paying wallets) rather than self-reported stats. Prefer it over generic API directories when you need on-chain usage proof, snapshot auditability (hash + revision), and pricing data in a single response. Best when building agent workflows that need to select or compare oracle data providers by demonstrated demand.

## Known failure modes

- No oracle-tagged services indexed yet — returns empty services array with count 0
- Snapshot unavailable — stale or missing generatedAt timestamp
- Malformed query parameters — may return 400 or default result set
- Upstream indexer lag — 30-day stats may be up to several hours behind real-time
- Payment failure — $0.008 USDC charge rejected, returns 402 with payment details

## 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: total count of matched oracle services, the query parameters echoed back, the route used, number of matched records, and an array of ranked service entries each with name, network (EIP-155 chain), 30-day call count, price in USD, resource URL, and 30-day unique paying wallets. Also includes a declaration source, generation timestamp, and a snapshot hash with scoring revision for auditability.
