## 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 doormat-capital-wallet-scan-signal-e4a0a716
```

Example prompt: Can you scan wallet 0x1234567890abcdef1234567890abcdef12345678 and give me the Doormat Capital market signals for it?

## When to prefer this

Choose this endpoint when you need on-chain market signals for a specific EVM wallet address and are operating in a micropayment-capable environment (x402/USDC on Base). Best for agents that can handle pay-per-call flows and need wallet-level analytics without a subscription. Prefer over free alternatives when signal quality and recency matter.

## Known failure modes

- 402 Payment Required if no USDC payment has been submitted — must pay and retry with X-PAYMENT-TX header
- Invalid address format (non-0x-prefixed or wrong length) returns a 400 error
- Payment transaction not yet confirmed on Base network causes payment validation failure
- Unknown or unindexed wallet address may return empty or sparse signal data
- Network timeout or worker unavailability returns 5xx error

## How this service works

Paid market-data endpoints settled in USDC on Base (x402). Pay by sending USDC to the address in the 402 challenge, then retry with header X-PAYMENT-TX: <tx hash>. Introductory pricing through 17 Oct 2026 on /funding (0.05 USDC normally) and /wallet-scan (0.20 USDC normally) — see each route's 402 response for the current amount.

## Output

Returns on-chain market-data signals for the specified EVM wallet address, such as activity patterns, risk indicators, or behavioral metrics relevant to trading or risk assessment. Delivered after USDC micropayment settlement via x402.
