# CYRE Guardian Intent Preflight

> CYRE Guardian Intent Preflight is a paid API for AI agents from cyre.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Grades Solana wallet addresses, mint authorities, and program IDs before a transaction is signed, returning explainable risk signals and a risk score — not a verdict.

## Facts

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 cyre-guardian-intent-preflight-3f1adf10
```

Example prompt: Before I sign this Solana transaction, can you preflight check the sender wallet 9xKm...abc and destination wallet 3rTn...xyz to see if there are any risk signals or suspicious patterns I should know about?

## When to prefer this

Use this endpoint when an AI agent needs to assess risk for a Solana-specific transaction before signing — especially when explainability matters (you want signals and patterns, not just a pass/fail). Prefer this over generic blockchain analytics when the focus is Solana, when you need per-transaction preflight checks on wallets, mints, and programs together, and when you want lightweight, per-call pricing at $0.01 USDC.

## Known failure modes

- Missing required 'from' wallet address returns a 400-level error
- Invalid base58 wallet address format causes a parsing error
- Unknown or brand-new program IDs may return limited signal data
- Network or chain data unavailability may return incomplete signals
- Rate limiting or payment failure (x402) if USDC payment not provided

## How this service works

Guardian Intent Preflight — before you sign a Solana tx, grade the from/to wallets, mint authorities, and program novelty. Explainable patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

## Output

Returns a JSON object with: an 'ok' boolean, a 'kind' string classifying the wallet pattern, a 'brief' human-readable explanation, a numeric 'score' (risk score), an array of 'signals' (explainable risk indicators), and a 'riskLevel' string (e.g. LOW, MEDIUM, HIGH). No binary verdict — agents receive patterns and scores to make their own decisions.
