## 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-deep-89445220
```

Example prompt: Show me the top oracle services on the x402 bazaar right now, ranked by how many unique paying wallets they've had in the last 30 days — I want real usage numbers, not just listings.

## When to prefer this

Choose this endpoint when you specifically need to discover oracle-category x402 services ranked by real economic activity (paying wallets and call volume) rather than self-reported listings. It is the right choice when you want a curated, usage-weighted leaderboard of oracle APIs rather than a flat directory or a broader multi-tag search.

## Known failure modes

- No oracle-tagged services indexed yet — returns empty services array with count 0
- Snapshot stale — generatedAt timestamp may lag real-time by indexing delay
- Rate limit or payment failure — HTTP 402 if USDC payment not attached or rejected
- Upstream index unavailable — may return HTTP 500 or timeout from Cloudflare Worker
- Malformed response if scoring revision changes between calls

## 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 a ranked array of oracle-tagged x402 services, each with name, network chain ID, 30-day call count, price in USD, resource URL, and unique payer count over 30 days. Also includes query metadata (route, operator, limit), total matched count, who declared the data, and a generatedAt timestamp with an implicit snapshot hash for auditability.
