## 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-business-finance-72d8ad8a
```

Example prompt: Show me the top 25 business and finance services on the x402 marketplace right now, ranked by unique paying wallets over the last 30 days, and include their prices and call volumes.

## When to prefer this

Choose this endpoint when you need market-verified, usage-ranked discovery of x402 services specifically in the business and finance domain, backed by real on-chain payment activity rather than self-reported metadata. Prefer it over generic API directories when you need signal from actual paying wallets and call volumes, or when you need an auditable snapshot receipt (hash + scoring revision) for reproducibility. Avoid if you need services from other domains (use sibling endpoints for risk, security, onchain, etc.) or if you need seller-level dossiers by hostname.

## Known failure modes

- No services match the business-finance tag (empty results list with count 0)
- Snapshot data may be stale if the indexer hasn't updated recently
- Payment failure if 0.032 USDC is not available in the calling wallet
- Worker timeout or 5xx if Cloudflare infrastructure is unavailable
- Malformed response if the underlying index is being rebuilt during a scoring revision

## 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 list of up to 25 business-finance x402 services, each with name, network (EIP-155 chain ID), 30-day call count, price in USD, resource URL, and unique paying wallets. Also includes query metadata (route, matched count, ranking parameters), the declaring agent, snapshot generatedAt timestamp, and a receipt with snapshot hash and scoring revision for auditability.
