## 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 glassnode-lightning-network-node-count-9760e2f2
```

Example prompt: Pull the Glassnode Lightning Network node count data for Bitcoin in JSON format so I can see how the number of LN nodes has changed over the past 24h intervals.

## When to prefer this

Use this endpoint when you need historical or current Lightning Network node count data specifically sourced from Glassnode's on-chain analytics platform, particularly when building dashboards, tracking BTC layer-2 adoption, or comparing network growth over time. Prefer this over generic crypto data sources when Glassnode's methodology and data quality are important.

## Known failure modes

- Missing required 'a' query parameter (must be 'BTC') returns a 400 error
- Invalid format value for 'f' parameter returns a 400 error
- Payment not provided or insufficient USDC balance causes a 402 Payment Required response
- Network timeout or upstream Glassnode data unavailability returns a 503 error
- Requesting an unsupported interval value for 'i' returns a 400 error

## How this service works
