Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 orionkr-xyz-4057b45f
```

Example prompt: Before I buy this Base memecoin, run a quick wallet risk probe on my address 0xABC...123 to check for unsafe token concentration, suspicious counterparties, and portfolio exposure — and tell me what the next safety check I should run before signing is.

## When to prefer this

Use this endpoint as the cheapest first step in an agentic Base memecoin trading loop when you need a low-cost wallet risk probe before committing to a full transaction safety check. Ideal for autonomous agents that need to gate repeated buy decisions with minimal upfront cost via x402 micropayments.

## Known failure modes

- Payment not included or insufficient USDC — returns 402 Payment Required
- Invalid or missing wallet/token address — returns 400 Bad Request
- Downstream Base node unavailable — returns 503 Service Unavailable
- Malformed x402 payment header — returns 402 with payment details
- Rate limit exceeded — returns 429 Too Many Requests

## How this service works

Paid API entrypoint for x402 buyers and agentic commerce workflows. Use as a first paid Orion call before Base memecoin signing or transaction execution.

## Output

Returns wallet exposure metrics, unsafe token concentration flags, suspicious counterparty signals, portfolio risk assessment, and the recommended next paid API call (/v1/base/transaction-safety) to invoke before signing or broadcasting a transaction.
