# P0 Agent Economy Index – Geo-tagged x402 Service Discovery

> P0 Agent Economy Index – Geo-tagged x402 Service 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 geo-tagged x402 services ranked by real 30-day call volume and paying-wallet counts, plus a broader agent-economy index across major protocols.

## 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-geo-tagged-x402-service-discovery-38eda784
```

Example prompt: Give me the top 25 geo-tagged x402 services ranked by payer count from the live agent economy index — I want to see which geography APIs real agents are actually paying for right now.

## When to prefer this

Use this endpoint when an agent needs to discover and rank live geo-tagged x402 services by genuine market demand (real 30-day calls and paying wallets), rather than relying on static directories or self-reported listings. Prefer it over generic API directories when the goal is to find location/geography APIs that agents are actively paying for on-chain. Also useful when you want a broader snapshot of the agent economy across protocols (Tempo MPP, Virtuals ACP, Olas, Masumi, MCP registry, etc.) in a single call with source-cited figures.

## Known failure modes

- No geo-tagged services indexed yet — returns empty services array with count 0
- Snapshot data stale if the 30-day window has not refreshed — generatedAt timestamp reveals age
- Invalid or unrecognized query parameters may return an error or unfiltered results
- Cloudflare Worker cold-start may add slight latency on first call
- Payment failure (insufficient USDC balance) results in HTTP 402 and no data returned

## 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 geo-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 query metadata (ranking dimension, limit, total matched services), the route used, a timestamp, and a 'declaredBy' field. Separately provides agent-economy index stats across protocols such as Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 registries, Solana agent registries, Base agent contracts, and the official MCP registry, each with agent/server counts, transaction or payment events, payer counts, and USD volume where published, with units and source cited.
