## How to call it through Zero

```sh
zero fetch --capability claw402-rootdata-changes-feed-0f002dba
```

Example prompt: Can you pull the RootData changes feed for everything that changed between January 1 2025 and January 31 2025?

## When to prefer this

Use this endpoint when you need to track or monitor changes in RootData crypto project data and want to pay per call in USDC without registering for an API key. Ideal for lightweight change-monitoring workflows or agents that periodically poll for updates.

## Known failure modes

- Empty data array returned if no changes exist in the specified time window
- Invalid or malformed begin_time/end_time formats may yield errors or empty results
- Payment failure via x402 protocol blocks access before the request is processed
- Service unavailability from the underlying vergex.trade or RootData provider returns non-200 responses

## How this service works

Backed by vergex.trade. Pay for any API with USDC. No API keys. No registration. Just a wallet.

## Output

A JSON object with a status code and a data array containing change records from RootData for the specified time window (or all recent changes if no time range is given).
