## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability keeperhub-blockchain-workflow-automation-checked-transfer-57a1351d -d '<json body>'
```

Example prompt: Trigger my KeeperHub 'checked-transfer-16zk' blockchain workflow to execute a validated on-chain transfer — run it now with the standard transfer parameters.

## When to prefer this

Choose this endpoint when you need to execute the specific 'checked-transfer-16zk' pre-configured KeeperHub blockchain workflow that includes validation checks before transferring funds. Prefer this over generic blockchain transfer APIs when you need the visual node-based workflow logic, conditional checks, and automation pipeline that has been pre-built in KeeperHub.

## Known failure modes

- Insufficient funds or balance check failure causing workflow abort
- Invalid or missing transfer parameters causing execution error
- Blockchain network congestion or RPC failure resulting in timeout
- Payment of 0.05 USDC not confirmed, blocking workflow execution
- Workflow node misconfiguration causing pipeline failure

## How this service works

Build powerful blockchain workflow automations with a visual, node-based editor. Built with Next.js and React Flow.

## Output

Returns the outcome of the checked-transfer workflow execution, including transfer status, transaction hash or confirmation details, and any validation check results from the node-based pipeline.
