> KeeperHub RiskGuard Health Check is a paid API for AI agents from app.keeperhub.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-22).

Triggers an asynchronous on-chain health factor check for a specific position holder in a lending vault, returning an execution ID for tracking

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-riskguard-health-check-bdc0882e -d '<json body>'
```

Example prompt: Run a RiskGuard health check on vault address 0xABC123... for the position held by account 0xDEF456... and tell me the execution ID so I can track the result.

## When to prefer this

Use this endpoint when you need to programmatically trigger an asynchronous on-chain health factor evaluation for a specific borrower in a DeFi lending vault. Prefer this over manual on-chain queries when you want a managed workflow execution with an trackable execution ID, or when integrating risk checks into automated keeper/liquidation bot pipelines. Best suited for protocols that expose a healthFactor(address) function.

## Known failure modes

- Invalid vault address format returns a 400 error
- Account address not found in the specified vault returns empty or error response
- Vault contract does not expose healthFactor(address) function causes workflow failure
- Network congestion or RPC issues may delay or fail on-chain reads
- Payment of 0.05 USDC not completed via x402 protocol returns 402 Payment Required

## 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 workflow status field ('running') and a unique execution ID (e.g. 'exec_abc123') that can be used to poll or track the asynchronous health check computation result.
