## 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-enrichment-tagged-service-discovery-1d130f9b
```

Example prompt: Pull the current top 25 enrichment-tagged services from the x402 agent economy index, ranked by 30-day unique paying wallets, and show me their names, prices, call counts, and payer counts.

## When to prefer this

Choose this endpoint when you need ranked discovery of x402 enrichment services backed by verified real 30-day usage metrics (calls and unique paying wallets) rather than self-reported or static listings. Prefer it over general API directories when you specifically need the agent-economy context, x402 payment compatibility, Base/EVM network scoping, and a cryptographically receipted snapshot for auditability.

## Known failure modes

- No enrichment-tagged services indexed yet — returns empty services array
- Payment not fulfilled — 402 response requiring USDC payment via x402 protocol
- Stale index — snapshot may lag real-time by up to hours depending on indexing cadence
- Network timeout on Cloudflare Worker — transient 503 or 504
- Malformed response if snapshot hash computation fails — incomplete receipt field

## 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 query parameters used, the total number of matched services, a ranked list (up to 25) of enrichment-tagged x402 services each with name, network, 30-day call count, USD price, resource URL, and 30-day unique payer count, plus metadata including snapshot generation timestamp and declaring agent.
