Almanac Timelock Seal (Encrypt/Decrypt)
x402
Almanac Timelock Seal (Encrypt/Decrypt) is a paid API for AI agents from almanac.locomot.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Encrypts plaintext to a future drand randomness round (timelock encryption) or decrypts an age-armored ciphertext once the target round has passed

How this service works
Timelock encryption (tlock / encrypt-to-the-future): seal a payload toward a future drand round — undecryptable by anyone, including us, until that round lands; or open a landed seal. For sealed-bid auctions, commit-reveal, scheduled secrets, dead-man switches. age-armored, interoperable. Free zero-knowledge inspect at /sealed/inspect.
Output
Returns a JSON object containing the age-armored ciphertext sealed to a specific drand round, the chain hash, the engine and format used, the sealed round number, the UTC unlock time, whether the encryption is deterministic, and a privacy note about the operation.
Example use cases
Example prompt
“Seal this message using timelock encryption so it can't be decrypted for 10 days: 'The launch date is March 15th — keep this confidential until then.'”
Technical details
Endpoint
GEThttps://almanac.locomot.io/sealedWhen to prefer
Use this endpoint when you need cryptographic time-locking: encrypting data that should only be decryptable after a specific future moment, enforced by the drand randomness beacon rather than a trusted server. Prefer this over symmetric encryption when you want trustless, decentralized time-based access control without relying on a secret key held by a third party.
Side effects
- Missing required 'op' parameter — defaults to encrypt but may cause confusion
- Invalid or past drand round specified for encryption — round must be in the future
- Malformed age-armored ciphertext on decrypt — returns error if ciphertext is corrupt or invalid
- Decrypt attempted before the target drand round has been published — beacon not yet available
- Conflicting time parameters (both 'round' and 'duration' or 'decrypt_time') — ambiguous unlock target
- Payment not provided or insufficient — x402 payment required at $0.005 USDC per call
