## 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-memecoin-tagged-x402-services-da980fa3
```

Example prompt: Show me the top 25 memecoin-tagged x402 services ranked by paying wallets over the last 30 days, including call counts and prices for each.

## When to prefer this

Choose this endpoint when you need a ranked, real-usage-backed list of x402 services specifically in the memecoin category, filtered by actual 30-day paying wallets rather than self-reported metadata. Prefer it over general x402 discovery routes when you want demand-validated memecoin APIs, and over broad economy index routes when you only care about the memecoin tag slice.

## Known failure modes

- No memecoin-tagged services indexed yet — returns empty list with count:0
- Snapshot data stale if index hasn't been refreshed recently
- Upstream x402scan data lag causing outdated call/payer counts
- Rate limit or payment failure for the $0.008 USDC per-call fee
- Malformed response if the worker is mid-deployment

## 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 up to 25 x402 services tagged 'memecoins', ranked by 30-day unique paying wallets. Each service entry includes its name, network (e.g. eip155:8453), 30-day call count, price in USD, resource URL, and payer count. The response also includes the total matched service count, the query parameters used, the route, who declared the data, and a generatedAt timestamp for snapshot provenance.
