## 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 x402-seller-wallet-fingerprint-24159d26
```

Example prompt: Can you pull the on-chain fingerprint for wallet address 0xAbC123...def456 on Ethereum so I can see its trading behavior before I interact with it?

## When to prefer this

Use this endpoint when you need a quick, keyless on-chain identity check for a specific wallet address before trading or interacting, and you want to pay per-call in USDC without managing API keys. Prefer it over manual chain explorers when your agent needs a structured, machine-readable fingerprint in a single call.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Unsupported chain identifier causes lookup failure
- Address with no on-chain history may return minimal or empty profile
- Payment failure (insufficient USDC) blocks the request
- Render cold-start latency may cause timeout on first request

## How this service works

Rug protection and decision-ready intelligence for autonomous trading agents. Keyless by design: no signup, no API key — pay a cent per request in USDC (x402). The /alpha/launches LAUNCH RADAR discovers what just launched AND rug-screens every candidate in one call, ranked per-token verdicts — the proactive 'give me safe alpha' call. /vet gives a single-token go/no-go in ONE call by fusing a COMPOSITE rug score (GoPlus static analysis + a LIVE Honeypot.is buy/sell simulation + serial-rugger check) with our SELF-COLLECTED liquidity-drain trend — a rug-in-progress signal that exists nowhere for free because it requires collecting reserves over time. One call is cheaper than the inference tokens you'd burn stitching 4 free APIs, and it stops your agent losing its whole position to a honeypot. Also: /onchain/liquidity drain detector, /screen batch watchlist check, /brief market regime, and raw feeds (prices, stocks, DEX pools, launches, perp funding/OI).

## Output

Returns a structured wallet fingerprint object containing on-chain behavioral signals, identity metadata, and risk-relevant profile data for the queried address. The exact schema is dynamic but typically includes activity patterns, association signals, and categorization relevant to DeFi trading risk.
