```

Example prompt: Can you do a quick risk scan on the Avalanche wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 and tell me the risk level, toxicity score, and any flags like scammer or sanctions that fired?

## When to prefer this

Use this endpoint when you need a fast, lightweight risk check specifically on the Avalanche (AVAX) network. It is lighter than a full scan — no USD volume breakdown — making it ideal for real-time compliance checks, pre-transaction screening, or off-ramp gating where speed matters. Prefer over the full scan when you only need a pass/fail decision or top-level risk flags without deep financial analytics.

## Known failure modes

- Missing or malformed address parameter returns a 400 error
- Non-EVM address format (e.g. non-0x-prefixed) may return validation error
- Address not found on Avalanche network may return empty traits with score 0
- Payment not included or invalid x402 payment header returns 402 Payment Required
- Rate limiting or overload may return 429 or 503
- ENS resolution failure if ENS name cannot be resolved

## How this service works

Scans Avalanche addresses or activity for fast on-chain insights.

## Output

Returns a JSON object with the queried address, a numeric toxicScore, a riskLevel enum (PASS/LOW/MIDDLE/CRITICAL), a shouldFlag boolean (true if toxicScore > 0), and an array of traits listing specific risk categories that fired (e.g. known_scammer, sanction_address, mixer_transfers), each with a risk contribution value, transaction count, and human-readable description.
