# P0 Agent Economy Index – Wallet Overlap / Multi-Service Payer Analysis

> P0 Agent Economy Index – Wallet Overlap / Multi-Service Payer Analysis is a paid API for AI agents from x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-21).

Returns cross-service wallet overlap statistics showing how many paying wallets use 2 or more x402 services in a 30-day window, including distribution, top co-purchased service pairs, and multi-service adoption share.

## 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-wallet-overlap-multi-service-payer-analysis-9927509f
```

Example prompt: Pull the latest x402 wallet overlap index and tell me how many wallets are paying for 2 or more services this month, what the top co-purchased service pairs are, and what the overall multi-service adoption share looks like.

## When to prefer this

Choose this endpoint when you need to understand cross-service wallet behavior in the x402 ecosystem — specifically co-purchase patterns, multi-service adoption rates, and service pair affinity. It is the only publicly available source computing payer overlap across the live x402 service market using real 30-day paid settlements. Do not use it for single-service demand ranking (use the Market Index endpoints), agent registry counts (use /economy routes), or L402/MPP protocol data.

## Known failure modes

- Stale snapshot: stale flag set to true if computation is older than expected refresh cadence
- Empty top_pairs: if fewer than 2 sellers have shared wallets in the window
- Coverage gaps: sellers_with_known_host may be less than total sellers, reducing pair resolution
- Chain exclusions: payments to high-volume non-API addresses excluded via api_price_max_usd filter
- Payment method not found: non-x402 protocols (L402, per-service MPP) are explicitly out of scope

## 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: total unique paying wallets, multi-service wallet count and share, a distribution map (1, 2, 3–5, 6+ services per wallet), top co-purchased service pairs with shared wallet counts and host names, chain and seller coverage metadata, window start/end timestamps, snapshot age, and source provenance with a note on methodology.
