## 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-in-dependencies-f9827d34
```

Example prompt: Show me the top 25 x402 dependency services ranked by paying wallets over the last 30 days, including their call counts and prices.

## When to prefer this

Choose this endpoint when you specifically want pre-ranked discovery of x402 services in the 'dependencies' category using real on-chain usage signals (30-day calls and unique paying wallets) rather than manually querying raw service registries or unranked lists. Prefer it over generic API directories when you need trust signals backed by actual payment activity and a verifiable snapshot receipt.

## Known failure modes

- Empty result set if no dependency-tagged services are indexed
- Stale snapshot if the indexing pipeline is behind
- HTTP 402 if payment is not provided or fails
- Malformed response if the scoring revision changes schema
- Rate limiting or worker timeout on Cloudflare edge

## 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 x402 services filtered to the 'dependencies' tag, each entry including service name, network chain ID, 30-day call count, 30-day unique payer count, price in USD, and resource URL. Also includes total matched count, the query parameters used, a snapshot hash for verification, the scoring revision, and a generatedAt ISO timestamp.
