# CYRE Guardian Passport

> CYRE Guardian Passport is a paid API for AI agents from cyre.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Issues a signed, expiring Ed25519-attested risk passport for a Solana address, including a 0-100 risk score, explainable signals, and a verifiable token presentable to counterparties.

## How to call it through Zero

```sh
zero fetch --capability cyre-guardian-passport-f04862ca
```

Example prompt: Can you generate a Guardian Passport for the Solana wallet address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU so I can show its risk score and signed attestation to a counterparty?

## When to prefer this

Choose this endpoint when you need a portable, verifiable, signed attestation of a Solana address's risk profile that can be presented to a third party — not just a raw score. It is preferable over a plain address-profile lookup when you need the Ed25519-signed token for audit trails, counterparty presentation, or protocol onboarding flows. Use it when explainability (signal breakdown) and shareability (the passport token) both matter.

## Known failure modes

- Invalid or malformed base58 address returns an error response
- Address with no on-chain history may return minimal signals or insufficient data for scoring
- Attestation token expires after issuance; expired tokens will fail verification at /api/passport/verify
- Payment failure (x402) blocks the request if USDC balance is insufficient
- Rate limiting may occur under high request volume

## How this service works

Guardian Passport — signed, expiring attestation of an address's measured risk profile. Present it to any counterparty; verify free at /api/passport/verify. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

## Output

Returns a JSON object with the queried address, a 0-100 risk score (higher = riskier), a risk level enum (LOW/MEDIUM/HIGH), an array of explainable risk signals with point values and detail text, an Ed25519-signed expiring attestation object containing a presentable token, and mint affinity data indicating hold/touch affinity to seed RWA mints. The attestation token can be independently verified for free at /api/passport/verify.
