## When to prefer this

Use this endpoint when you need the specific Difficulty Ribbon Compression metric from Glassnode for Bitcoin — particularly for assessing miner stress, identifying potential market bottoms, or quantifying how compressed the mining difficulty ribbon is over time. Prefer this over generic price feeds or other on-chain metrics when your analysis specifically requires the normalized spread of the difficulty ribbon.

## Known failure modes

- Missing required 'a' query parameter (asset symbol) returns a 400 error
- Invalid asset symbol (non-BTC value) rejected since only 'BTC' is supported
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Invalid format parameter returns an error or defaults to JSON
- Service unavailability or upstream Glassnode data delay returns a 5xx error
