How this service works
Guardian Lockbox Match — check a proposed pay against a sealed pre-pay lockbox (intentHash + optional pins). Catch bait-and-switch. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md
Output
Returns a pattern-based match result indicating whether the proposed payment aligns with the sealed lockbox intentHash and pins, flagging bait-and-switch signals. Provides patterns, not final verdicts — highlighting discrepancies between the sealed intent and the current proposal.
Example use cases
Pre-payment bait-and-switch check
“I just got a payment proposal but I sealed my intent earlier — run a lockbox match with my token qr9t2wXpL and intentHash 0x4f2a...c8e1 to make sure the pay destination hasn't been switched on me.”
Agent escrow release guard
“Before my agent releases the escrow payment, verify the proposed pay matches the original sealed lockbox — token is agnt_lock_88z and the intentHash I sealed was 0xd3b0...1f9a.”
DeFi settlement integrity check
“I'm about to settle a trade but want to confirm nothing changed since I locked my intent — can you match lockbox token settle_7k2mN against intentHash 0x9c11...e4d7 to catch any tampering?”
Technical details
Endpoint
GEThttps://cyre.dev/api/lockbox/matchWhen to prefer
Use this endpoint when an AI agent or user has previously sealed a payment intent via CYRE Guardian Intent Lockbox and now needs to confirm the proposed payment hasn't been altered before approving or signing. Prefer this over generic hash comparison when you need the CYRE pattern-based bait-and-switch detection layer tied to a sealed lockbox workflow.
Side effects
- Missing or invalid token returns an error — token is required
- intentHash mismatch returns a no-match pattern signal
- Expired or tampered lockbox token may return invalid seal error
- Malformed query parameters return 400-level errors
- Lockbox not found for the given token returns not-found pattern
