How this service works
Build powerful blockchain workflow automations with a visual, node-based editor. Built with Next.js and React Flow.
Output
Returns a freshness status indicating whether the specified premise is current or stale, along with a timestamp, validation result details, and any relevant on-chain verification metadata from the workflow execution.
Example use cases
On-chain data staleness detection
“Can you run a freshness check on my blockchain premise to see if the on-chain data is still current, or if it's gone stale and needs updating?”
Automated claim validity verification
“I need to verify whether the premise I registered on KeeperHub is still valid — run the freshness check workflow and let me know if it's expired or still good.”
Pre-action blockchain state check
“Before I trigger my next smart contract action, can you use KeeperHub to check the freshness of the premise state so I know the underlying data is still accurate?”

Endpoint
POSThttps://app.keeperhub.com/api/mcp/workflows/premise-freshness-check/call?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify whether a specific blockchain premise or on-chain data claim is still fresh and valid, particularly within automated workflows. Prefer this over generic REST validators when you need the result to be backed by KeeperHub's visual workflow automation engine and blockchain-native verification.
