## When to prefer this

Choose this endpoint when you need a quick, pay-per-use lookup of the crypto Fear & Greed Index without maintaining a subscription to a dedicated sentiment data provider. Ideal for agents that occasionally need market sentiment context as part of trading signals, portfolio decisions, or market briefings, and prefer micropayment access via USDC on Base rather than managing API keys.

## Known failure modes

- Upstream data source unavailable returns an error or stale data
- Payment not processed (insufficient USDC balance) results in 402 rejection
- Rate limiting if called too frequently
- Malformed response if the underlying index provider is down
