## 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-social-services-discovery-c26e2547
```

Example prompt: Show me the top 25 social x402 services ranked by paying wallets over the last 30 days, along with their call volumes and prices.

## When to prefer this

Use this endpoint when you specifically need to discover social-category services in the x402 market ranked by real usage signals (30-day calls and unique paying wallets). Prefer this over generic API directories when you need on-chain payment-verified usage data and a verifiable snapshot receipt for auditability. Best suited for agents building social automation stacks or evaluating social APIs with proven market demand.

## Known failure modes

- No services match the social tag filter — returns empty services array with matched:0
- Snapshot index temporarily stale — generatedAt timestamp may lag real-time by minutes
- Invalid or missing parameters return a 4xx with an error message
- Service unavailable due to Cloudflare Worker cold start or rate limiting — 5xx response
- Payment not processed correctly — 402 response requiring valid x402 payment header

## 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 count of returned services, the query parameters used (ranking by payers, top-N, social tag filter), the total number of matched services in the index, and an array of service records each with name, network chain, 30-day calls, price in USD, resource URL, and unique payers over 30 days. Also includes a receipt with snapshot hash, scoring revision, declared-by field, and generation timestamp.
