## When to prefer this

Use this endpoint when you need a quick, single-call lookup of the crypto market's Fear & Greed Index without building your own aggregation pipeline. It is best suited for enriching trading decisions, daily briefings, or automated workflows that factor in market sentiment, especially when paying per-request via USDC is acceptable and a dedicated sentiment-data subscription is not already in place.

## Known failure modes

- Upstream data source unavailable returns generic error in result object
- Stale data if the index provider has not updated recently
- Malformed response if the kite-hub proxy encounters an internal error
- Payment failure if USDC balance is insufficient before the request is processed
