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 freysa-intelligence-security-layer-44dd4054
```

Example prompt: Before I swap into this token at 0x1234...abcd, can you run a security check on it — look for rug pull signals, contract vulnerabilities, and any suspicious wallet activity linked to it?

## When to prefer this

Choose this endpoint when an AI agent needs real-time on-chain security intelligence before executing crypto transactions, evaluating unknown tokens, or interacting with unfamiliar wallets. It is particularly valuable for DeFi agents that need pre-trade risk checks, automated portfolio managers screening new assets, or any agent workflow where blockchain security validation is a prerequisite step. Prefer it over generic LLMs because it is specifically prompted and tuned for web3 security use cases with on-chain context.

## Known failure modes

- Insufficient USDC balance or failed x402 payment results in 402 Payment Required response
- Ambiguous or incomplete prompt may yield generic or unhelpful security analysis
- Token or wallet address not found on-chain returns no data or inconclusive result
- Rate limiting or service unavailability returns 429 or 5xx errors
- Novel scam vectors not in training data may be missed by the underlying model
