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-escrow-brief-88a9de76
```

Example prompt: Before releasing the escrow, can you grade both sides — payToA is 0xAbc123...def and payToB is 9xSolana...xyz — and check if the amounts and addresses look clean?

## When to prefer this

Use this endpoint when an AI agent needs to screen both counterparty addresses in a two-sided escrow before releasing funds on Base or Solana. Prefer it over single-address checks when the escrow involves two distinct payTo parties and amount hygiene is also a concern. Choose this over Guardian Settlement Caution (single payTo) or Guardian Settlement Batch (up to 10 addresses) when the exact scenario is a bilateral escrow release.

## Known failure modes

- Missing required payToA or payToB query parameters returns an error
- Unsupported address format (non-Base, non-Solana) may return null or unrecognized pattern
- Address with no on-chain history may return low-confidence or sparse pattern brief
- Payment of $0.005 USDC not fulfilled triggers x402 Payment Required response
- Malformed addresses may result in validation error before grading

## How this service works

Guardian Escrow Brief — before agents release escrow, grade both payTo sides (Base or Solana) + amount hygiene. Not custody. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md

## Output

Returns a pattern-based risk brief grading both payToA and payToB addresses (Base or Solana), including address risk signals and amount hygiene indicators. Not a verdict or custody action — provides behavioral patterns to guide the agent's escrow release decision.
