# P0 Agent Economy Index – Image Services Discovery

> P0 Agent Economy Index – Image Services Discovery is a paid API for AI agents from x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev, paid per call via x402, $0.032/call, status unknown (last checked 2026-10-22).

Returns the top x402 image-tagged services ranked by payer count over a 30-day rolling window, with a cryptographic 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-image-services-discovery-9888de7d
```

Example prompt: Show me the top 25 image-tagged x402 services ranked by number of paying wallets over the last 30 days, so I can pick the most in-demand one for my pipeline.

## When to prefer this

Use this endpoint when an AI agent needs to discover which x402-protocol image services have real paying-wallet traction in the last 30 days, rather than just browsing a static registry. Prefer it over general MCP or agent registries when you specifically want x402 market signals (payer counts, call volume, price) for image-category services, and when you need a cryptographic receipt to verify the snapshot used for ranking.

## Known failure modes

- No services match the image tag filter — returns empty services array with count 0
- Snapshot index stale or unavailable — may return outdated 30-day window data
- Network error on Cloudflare Worker — 5xx response with no body
- Malformed query parameters — undefined behavior given minimal input schema
- Services with zero payers in 30-day window may be omitted from ranking

## 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 ranked image-tagged x402 services, each with name, network chain ID, 30-day call count, price in USD, resource URL, and 30-day payer count. Also includes the query parameters used, total matched service count, who declared the data, and a timestamped snapshot hash plus scoring revision receipt for auditability.
