## 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 openclaw-buyerwatch-x402-diagnostics-d8b0e21b
```

Example prompt: Run a BuyerWatch diagnostic on wallet address 0xAbC123...456 — pay the $0.05 USDC fee via x402 using the OpenX402 facilitator and give me the results.

## When to prefer this

Use this endpoint when you need diagnostic buyer-watch data gated behind a verifiable x402 micropayment and are operating with the OpenX402 facilitator. Ideal for agents testing or operating within the x402 HTTP payment protocol ecosystem, or when you need to retrieve buyer signals for a specific Ethereum recipient address and can authorize a $0.05 USDC EIP-3009 payment.

## Known failure modes

- HTTP 402 returned if payment header is missing or payment not completed — response includes EIP-3009 extras needed to initiate payment
- Invalid or malformed payTo address results in a 400 error
- Wrong facilitator (not OpenX402) may cause payment rejection
- Insufficient USDC balance causes payment failure before data is returned
- Network timeout if the blockchain payment confirmation is slow

## How this service works

Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.

## Output

A JSON object containing diagnostic data about buyer watch signals or activity associated with the provided recipient address, returned only after successful x402 micropayment of $0.05 USDC via EIP-3009 authorization through the OpenX402 facilitator. Unpaid requests receive HTTP 402 with EIP-3009 payment details.
