How this service works
Guardian Intent Lockbox — seal your intentHash before you pay so any party can later prove the hash was locked pre-settle. Bearer holds the token. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md
Output
Returns a bearer token representing the sealed lockbox entry, confirming that the provided intentHash was recorded pre-settlement for the given actor. The token can later be presented to prove the hash was locked before payment occurred.
Example use cases
Pre-payment intent sealing for escrow
“I'm about to release escrow to a contractor — seal intentHash '0xdeadbeef42' for actor '0xMyWallet' in the lockbox right now so there's a tamper-proof record that I committed to this intent before the payment goes through.”
Multi-party payment dispute prevention
“We're settling a deal and the other party wants proof I locked in the payment intent before we agreed on terms — can you seal intentHash '0x99ffa1c2' under actor '0xAgentWallet' in the CYRE Guardian lockbox?”
Agentic workflow pre-settlement commit
“My agent is about to trigger an x402 payment — first seal intentHash '0xf00dface' for actor '0xPayerAddress' so we have a lockbox record proving the intent was committed before the transaction settled.”
Technical details
Endpoint
GEThttps://cyre.dev/api/lockboxWhen to prefer
Use this endpoint when you need a cryptographically verifiable, time-stamped record that an intentHash was committed before a payment or settlement event occurred — particularly in multi-party or disputed transactions where pre-settlement proof matters. Prefer this over on-chain logging when you need low-cost, fast commitment without writing directly to a blockchain. Use before calling Guardian Lockbox Match to verify a subsequent payment against the sealed record.
Side effects
- Missing required 'actor' or 'intentHash' query parameters returns a 400 error
- Invalid intentHash format may be rejected
- Duplicate sealing of the same intentHash/actor combination may return a conflict or idempotency error
- Payment failure (x402) if USDC balance is insufficient or x402 header is missing
- Network timeouts if the lockbox service is temporarily unavailable
