## 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-uptime-tagged-x402-services-f3bb0087
```

Example prompt: Show me the top 25 uptime-tagged services in the x402 agent economy, ranked by how many unique paying wallets they've had in the last 30 days, so I can find the most battle-tested uptime APIs agents are actually using.

## When to prefer this

Choose this endpoint when you specifically need ranked discovery of x402 services in the uptime category, filtered and sorted by real economic activity (paying wallets and call counts) rather than simple listings. Prefer this over generic service directories when you want evidence of actual agent spending, or when building an agent that needs to select a proven uptime service from the live x402 market. Not suitable for L402 listings, MPP per-service data, or non-uptime service categories.

## Known failure modes

- No services tagged 'uptime' currently indexed — returns empty services array with count 0
- Payment not attached or insufficient — 402 response requiring USDC payment
- Snapshot stale — generatedAt timestamp may lag real-time by index refresh interval
- Input schema mismatch — malformed query properties may return unexpected or empty results
- Worker downtime — Cloudflare Worker unavailable, returns 5xx error

## 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 route identifier, query parameters used, total matched service count, and an ordered array of up to 25 uptime-tagged x402 services. Each service entry includes its name, network chain ID, 30-day call count, price in USD, resource URL, and 30-day unique payer count. A 'generatedAt' timestamp and 'declaredBy' field indicate snapshot freshness and declaration source.
