# P0 Agent Economy Index – Data-Workflow Services Discovery

> P0 Agent Economy Index – Data-Workflow Services Discovery is a paid API for AI agents from x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-10-11).

Returns a ranked list of the top x402-protocol data-workflow services, scored by real 30-day call volume and unique paying wallets, with a snapshot receipt.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-data-workflow-services-discovery-2b909b87
```

Example prompt: Pull the top 25 data-workflow services from the x402 agent economy index, ranked by unique paying wallets over the last 30 days, so I can see which data pipeline APIs real agents are actually spending money on.

## When to prefer this

Use this endpoint when you need a real-activity-ranked leaderboard of x402 data-workflow services — specifically when you want services sorted by genuine paying-wallet demand rather than self-reported metrics. Prefer it over general API directories when you need the x402 protocol's economic signal (calls, payers, price) for the data-workflow vertical specifically. Not suitable if you need L402, per-service MPP listings, or cross-protocol totals.

## Known failure modes

- No services indexed for tag – returns empty services array with count 0
- Worker cold-start or upstream indexer lag – may return stale snapshot with older generatedAt timestamp
- Network timeout – Cloudflare Worker may return 504 if upstream index is unavailable
- Malformed response if snapshot hash is being recomputed during the request

## 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 x402 services tagged 'data-workflow', each with service name, network chain ID, 30-day call count, USD price, resource URL, and 30-day unique paying wallet count. Also includes total matched service count, query metadata, route, declaring entity, and a snapshot timestamp for auditability.
