# KeeperHub Yield Snapshot Workflow

> KeeperHub Yield Snapshot Workflow is a paid API for AI agents from app.keeperhub.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-22).

Triggers a yield snapshot blockchain workflow for a specified crypto asset (ETH, BTC, or USDC) and returns an execution ID for tracking.

## 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-yield-snapshot-workflow-11d4ad0b -d '<json body>'
```

Example prompt: Trigger a yield snapshot on KeeperHub for USDC and let me know the execution ID so I can track the result.

## When to prefer this

Choose this endpoint when you need to capture a point-in-time yield snapshot for ETH, BTC, or USDC via an automated blockchain workflow, especially in DeFi monitoring pipelines or scheduled yield audits. It is best suited when you want a lightweight trigger-and-track pattern using an execution ID rather than a synchronous full data response.

## Known failure modes

- Invalid asset value (not eth, btc, or usdc) returns a validation error
- Missing required 'asset' field returns a 400 bad request
- Payment failure or insufficient USDC balance causes a 402 Payment Required response
- Workflow engine unavailable returns a 503 or timeout error
- Execution may be queued and not immediately reflected if system is under load

## 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') that can be used to track or retrieve the results of the yield snapshot workflow.
