# CYRE Guardian Pulse

> CYRE Guardian Pulse 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).

Polls up to 10 Solana wallet addresses and returns only those flagging risk, dormancy, or burst patterns — silent wallets are filtered out.

## 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-pulse-0f0d5114
```

Example prompt: Before I pay out to these Solana wallets — DRk1aB2c3D4e5F6g7H8i9J0k, AMnP2q3R4s5T6u7V8w9X0y1Z, and 3 others — screen all five for risk, dormancy, or burst patterns and only tell me about the ones that look suspicious.

## When to prefer this

Choose this endpoint when you need to batch-screen up to 10 Solana wallet addresses quickly and only care about the risky or anomalous ones — it's optimized for noise reduction, returning only hits rather than full reports on every address. Prefer it over single-address lookups when processing multiple counterparties before a payment or settlement round. It is Solana-specific; use sibling endpoints for Base or cross-chain scenarios, or Guardian Settlement Batch for ranked scoring across payer+payees.

## Known failure modes

- Invalid or malformed Solana address in the list causes rejection
- Exceeding the 10-address limit returns an error
- Missing required 'list' query parameter returns a validation error
- Payment failure (x402) blocks the request
- No hits returned when all wallets are clean — empty result is a valid success
- Network timeout if Solana data is temporarily unavailable

## How this service works

Guardian Pulse — poll up to 10 Solana counterparties and return only risk/dormant/burst hits (quiet wallets stay quiet). Optional prior fingerprints. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

## Output

A filtered list of only the Solana addresses (from the submitted batch of up to 10) that triggered a risk, dormancy, or burst pattern hit — wallets with no signals are omitted from the response. Each hit includes pattern type and associated signals, not a final verdict.
