## When to prefer this

Choose this endpoint when you need historical crypto market sentiment data in the form of the Fear & Greed Index, especially when you want trend summaries (7d/30d averages, trend direction, extreme fear day counts) alongside raw daily values. It is priced at $0.002 per call via x402/USDC on Base, making it suitable for agent workflows that need periodic sentiment checks without high overhead.

## Known failure modes

- Payment not received or invalid x402 USDC payment header — returns 402 Payment Required
- Upstream data source unavailable — may return 503 or empty history array
- Invalid query parameters — returns 400 Bad Request
- Rate limiting if too many calls in short succession
