## 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-hashing-services-discovery-46652b22
```

Example prompt: Show me the top 25 hashing services in the x402 agent economy ranked by number of paying wallets over the last 30 days, with their prices and call volumes.

## When to prefer this

Use this endpoint when you need to discover and rank x402-native hashing services by real 30-day usage signals (payer counts and call volume) rather than self-reported listings. Prefer it over generic API directories when you specifically want services priced in USDC on EVM-compatible networks (especially Base) that are actively used by paying agent wallets. Not suitable if you need hashing service discovery outside the x402 protocol, or if you want L402 or per-service MPP listings.

## Known failure modes

- No hashing services indexed yet — returns empty services array with count 0
- Payment not attached or insufficient — returns 402 Payment Required before data is served
- Worker cold-start or timeout — may return 503 or empty response under load
- Snapshot stale — generatedAt timestamp may lag real-time by the indexing window
- Schema mismatch — input properties field ignored silently, defaults applied

## 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 hashing services from the live x402 service market, each with name, blockchain network, 30-day call count, price in USD, resource URL, and 30-day payer count. Also includes the matched total service count, the query parameters used, the route, a 'declaredBy' field, and a generatedAt ISO timestamp anchoring the snapshot.
