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' string (e.g. 'exec_abc123') that can be used to track or poll the asynchronous workflow execution result
Example use cases
Pre-payroll treasury validation
“Run a preflight check on our treasury wallet 0x1234567890abcdef1234567890abcdef12345678 — we need 2.50 ETH to cover this month's contractor payroll, confirm there's enough before we proceed.”
DAO disbursement readiness check
“Before we trigger the DAO grant disbursement, do a preflight on 0xdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef and verify we have at least 0.75 ETH ready to go.”
Automated treasury audit before token distribution
“Check treasury 0xfeedface000000000000000000000000feedface to see if it holds the 3.00 ETH we need for the scheduled token distribution run this week.”
Technical details
Endpoint
POSThttps://app.keeperhub.com/api/mcp/workflows/payroll-preflight/callWhen to prefer
Choose this endpoint when you need to programmatically verify that a specific Ethereum treasury address holds sufficient ETH before triggering a bulk payroll, grant disbursement, or payout run — especially in automated agentic pipelines where you want to gate payment execution on a balance check. Prefer this over a raw RPC balance call when you want the check wrapped in a trackable workflow execution with an audit trail.
Side effects
- Invalid treasury address format (not a valid 0x Ethereum address) — likely 400 error
- totalRequired value not parseable as a decimal ETH string — likely 400 or validation error
- Treasury address has insufficient funds — workflow may complete but return a failed preflight result
- Workflow execution engine unavailable — 500 or timeout
- Payment of 0.01 USDC not processed correctly via x402 — payment required or authorization error
