## When to prefer this

Use this endpoint when you need live Deribit-specific perpetual futures data including funding rates, basis, and open interest for BTC or ETH. Prefer this over generic crypto price APIs when funding rate and derivatives-specific metrics are required, or when the user explicitly references Deribit perps.

## Known failure modes

- Invalid coin parameter (not BTC or ETH) returns an error
- Deribit API unavailable or rate-limited results in upstream failure
- Missing ?coin= parameter may return an error or default to one coin
