## 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 crest-x402-competitor-payer-intelligence-b711f7b0
```

Example prompt: Pull the payer intelligence report for the x402 competitor service at address 0x5d6dF6b10C54617dac4Bf9993ad9fA384b7B36d3 — I want to see their whale payers, revenue totals, churn rate, and whether there's a poaching opportunity for us.

## When to prefer this

Use this endpoint when you need on-chain competitive intelligence about who is paying a specific x402 service on Base mainnet — especially to identify high-value whale payers, assess competitor revenue, benchmark churn, or find wallet overlap for poaching opportunities. Prefer this over generic blockchain explorers when you need pre-processed payer clustering and behavioral scoring rather than raw transaction data.

## Known failure modes

- Invalid or malformed wallet address returns a 400 error
- Address not found on Base mainnet x402 ecosystem returns empty or minimal data
- Insufficient USDC balance for the $1.20 per-call fee results in payment failure (402)
- Network congestion on Base mainnet may cause timeout
- Address with very few payers returns low-confidence insights

## How this service works

Crypto market data, DeFi analytics, and x402 ecosystem intelligence via pay-per-request USDC on Base mainnet.

## Output

Returns a JSON object containing: a list of individual payer wallets with cluster labels, whale scores, payment counts, and spend totals; a summary with total revenue, unique payers, avg payment, and premium ratio; and insights including growth trend, 30-day churn rate, whale concentration, and a poaching opportunity score. Also includes the data sources and query timestamp.
