## 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-news-services-07a884cf
```

Example prompt: Show me the top x402 news services ranked by real 30-day usage and paying wallets — I want to know which news APIs on the x402 market are actually getting paid traffic right now.

## When to prefer this

Choose this endpoint when you specifically need to discover and rank x402 micropayment-gated news services by verified on-chain usage metrics (calls and paying wallets over 30 days). It is preferable over generic API directories because rankings are backed by real payment data rather than self-reported stats, and the verifiable snapshot receipt enables auditability. Use it when you want to find which news APIs on the x402 ecosystem are genuinely in demand before integrating or recommending one.

## Known failure modes

- No services match the 'news' tag — returns empty services array with count 0
- Snapshot index is stale or unavailable — may return outdated call/payer counts
- Payment of $0.008 USDC not fulfilled — 402 Payment Required response blocking access
- Worker timeout or Cloudflare edge error — 5xx response with no data
- Malformed response if indexer has not yet processed recent service registrations

## 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 the count of returned services, the query parameters used (by, op, limit, tag filter), the route, total matched services in the index, an ordered array of service objects (each with name, network, calls30d, payers30d, priceUsd, resource URL), who declared the data, and a generatedAt ISO timestamp plus snapshot hash and scoring revision for auditability.
