## 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 spraay-wallet-address-classifier-35a761ae -d '<json body>'
```

Example prompt: Can you classify the wallet address 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE and give me a risk score — I need to know if it's high-risk before we process a payment to it.

## When to prefer this

Choose this endpoint when you need a fast, AI-driven risk score and category label for a single blockchain address as part of a compliance check, payment pre-screening, or due-diligence workflow — especially when you want machine-learning-based classification rather than a pure rules-based or OFAC sanctions list lookup (use the sibling OFAC SDN endpoint for that). Prefer this when you want a holistic wallet risk profile beyond just sanctions matching.

## Known failure modes

- Invalid or malformed wallet address returns a 400 error
- Unsupported chain or address format may yield no classification
- Payment not included or insufficient USDC triggers a 402 payment required response
- Address too new or low-activity may result in a low-confidence classification
- Network timeout or inference backend unavailability returns a 5xx error

## How this service works

AI-powered wallet classification with risk scoring.

## Output

Returns an AI-generated wallet classification label (e.g. exchange, DeFi protocol, mixer, high-risk entity) along with a numeric or categorical risk score indicating the likelihood the address is associated with illicit or suspicious activity.
