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 JSON object with a status field (e.g. 'running') and an executionId (e.g. 'exec_abc123') representing the asynchronous lookup of the verifier's public verdict record for the given intent hash.
Example use cases
Confirm intent approval before execution
“Before we proceed with the on-chain action, check whether verifier 0x1234abcd... has issued a verdict on intent hash 0xdeadbeef... in the IntentRegistry — I only want to continue if it's been verified.”
Audit trail for governance workflow
“I need to audit whether the intent we committed last week was verified — can you pull the public verdict from verifier 0x9876fedc... for intent hash 0xabc00123... on KeeperHub?”
Agent pipeline verification gate
“My automated workflow needs to check if intent hash 0x5a6b7c8d... has been approved by verifier 0xf1e2d3c4... before triggering the next step — look up the verdict record now.”
Technical details
Endpoint
POSThttps://app.keeperhub.com/api/mcp/workflows/assay-verify/call?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically check whether a specific blockchain intent has received a public verdict from a known verifier address, particularly within automated KeeperHub workflows that gate further actions on intent approval. Prefer this over manual chain queries when you need the result returned via an MCP-compatible interface integrated into a node-based automation pipeline.
Side effects
- Invalid or malformed verifier address returns an error
- Intent hash not found in IntentRegistry returns empty or error response
- Intent hash not produced by assay_hash_intent tool may be rejected as non-canonical
- Payment failure (x402) results in 402 response before processing
- Verifier has not yet submitted a verdict, returning no record
- Network or blockchain RPC timeout causing delayed or failed response
