## How to call it through Zero

```sh
zero fetch --capability pulsescanner-validators-missed-proposals-ccbb7af1
```

Example prompt: Show me the PulseChain validators that missed the most proposals over the last 30 days, ranked from worst to best — give me the top 20.

## When to prefer this

Use this endpoint when you need to identify or rank PulseChain validators by missed proposal performance over a defined historical window. Prefer this over raw block or slot endpoints when the goal is comparative validator reliability analysis or staking due diligence, rather than inspecting a single slot or block.

## Known failure modes

- Invalid window value returns an error (only 1d, 7d, 30d, 90d accepted)
- Invalid cursor causes pagination error
- Exceeding limit bounds returns a validation error
- No validators found for the window returns an empty list
- Payment not provided or insufficient USDC balance returns 402 Payment Required

## How this service works

## Output

A paginated, ranked list of PulseChain validators ordered by number of missed beacon proposals within the chosen time window (1d, 7d, 30d, or 90d). Each entry includes the validator index and missed proposal count. Supports cursor-based pagination and a configurable result limit.
