Technical details
Endpoint
GEThttps://finance-api.kdlcfa.workers.dev/crypto-fear-greedWhen to prefer
Use this endpoint when you need a quick, single-number gauge of overall crypto market sentiment without constructing complex queries. It is ideal for dashboards, trading signal workflows, or any agent that needs to contextualize crypto market mood. Prefer it over scraping or parsing news headlines when a standardized, numeric sentiment score is needed.
Side effects
- Upstream Alternative.me API unavailability returns an error or stale data
- Rate limiting or Cloudflare Worker timeout if the upstream source is slow
- Score may be up to 24 hours old since it is a daily index, not real-time
