## 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 pulsescanner-beacon-epochs-5bb3d6ce
```

Example prompt: Pull the last 10 beacon epochs from PulseChain and show me each epoch's participation rate so I can see how well validators have been performing recently.

## When to prefer this

Choose this endpoint when you need a paginated feed of recent PulseChain beacon epochs with participation metrics. It is ideal for monitoring validator engagement trends over time or building dashboards that display epoch-level consensus health on PulseChain (chain id 369). Use sibling endpoints for slot-level detail, individual block data, or aggregate chain-wide totals.

## Known failure modes

- Invalid or expired cursor value returns an error or empty results
- Limit parameter out of allowed range may return an error
- Payment not included or insufficient causes HTTP 402 rejection
- Chain temporarily unavailable returns a service error
- No epochs available yet returns an empty list
