## 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 p0-agent-economy-index-generator-services-discovery-f7447c6e
```

Example prompt: Show me the top 25 generator services on the x402 agent economy index, ranked by how many paying wallets they've had in the last 30 days.

## When to prefer this

Choose this endpoint when you need ranked, real-usage-backed discovery of x402 generator services specifically — i.e. when you want payer-weighted rankings rather than a raw directory listing. Prefer it over generic API directories when you need 30-day activity signals and pricing data in one call, and when you're operating within the x402/Base agent economy and need a receipt-backed snapshot for auditability.

## Known failure modes

- Service may return empty results if no generator-tagged services are indexed
- Snapshot data may be stale if indexing pipeline is delayed
- HTTP 402 payment required if USDC payment header is missing or insufficient
- Non-standard input schema may cause unexpected filtering behavior
- Rate limiting or worker errors may return 5xx responses from Cloudflare

## 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 generator-tagged x402 services, each with name, network identifier, 30-day call count, USD price, resource URL, and 30-day payer count. Also includes total matched service count, query parameters echoed back, route, a generatedAt ISO timestamp, and the snapshot hash for receipt/auditability.
