Example prompt: What's the current median Lightning Network channel size for Bitcoin according to Glassnode — can you get the latest daily figure in native BTC units?

## When to prefer this

Use this endpoint when you need the median (typical) Lightning Network channel size as a time series for Bitcoin, sourced from Glassnode's professional-grade on-chain data. Prefer this over general blockchain explorers when you need structured, analytics-ready historical data with clean timestamped records specifically about LN channel capacity distribution.

## Known failure modes

- Missing required 'a' query parameter (must be 'BTC') returns a 400 Bad Request
- Invalid or unsupported interval value returns an error
- Payment not provided or insufficient — returns HTTP 402 Payment Required
- Rate limiting or quota exceeded returns 429
- Data may not be available for all historical periods, returning empty arrays

## How this service works
