## When to prefer this

Use this endpoint when you need historical or current counts of public Lightning Network channels for Bitcoin, particularly for tracking network growth, adoption trends, or off-chain payment infrastructure analysis. Prefer this over on-chain metrics when the user specifically asks about Lightning Network capacity or channel statistics.

## Known failure modes

- Missing required 'a' query parameter (asset symbol) returns an error
- Invalid asset symbol other than 'BTC' returns validation error
- Payment not processed correctly results in 402 Payment Required
- Rate limiting or quota exceeded returns 429
- Endpoint returns empty array if data is unavailable for the requested interval

## How this service works

Lightning Network Number of Channels — The number of public Lightning Network channels. The Lightning Network works by creating payment channels between two parties, where multiple transactions can be made without each individual transaction being recorded on the Bitcoin blockchain. These transactions are instead recorded off-chain, which makes them faster and cheaper. Data by Glassnode.

## Output

An array of timestamped data points, each containing a Unix timestamp ('t') and the number of public Lightning Network channels ('v') at that point in time, reflecting daily resolution for Bitcoin.
