Example prompt: What's today's Crypto Fear & Greed Index from alternative.me, and can you also show me how the sentiment has shifted over the last 14 days?

## When to prefer this

Choose this endpoint when you need the current or recent-historical Crypto Fear & Greed Index specifically sourced from alternative.me, with up to 30 days of daily history. It is a lightweight lookup with no authentication required and very low cost per call, making it ideal for automated daily monitoring, trading context enrichment, or sentiment dashboards. Prefer this over scraping alternative.me directly or building custom aggregations.

## Known failure modes

- Upstream alternative.me API unavailable — returns an error or empty data
- days parameter out of range (must be 1-30) — may return default 7-day history or an error
- Stale data if alternative.me has not yet published today's index
- Network timeout from Cloudflare Workers to upstream API
