## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.05 USDC) machine-readable Fear & Greed index and news sentiment score for financial/crypto markets in an AI agent workflow that already handles x402 micropayment flows on Base mainnet. Prefer it over free alternatives when you need reliable pay-per-use access without API key registration, or when building an agent that must make autonomous trading or portfolio decisions based on market mood.

## Known failure modes

- Payment not processed — x402 payment on Base mainnet required before data is returned
- Service unavailable — hosted on Render free tier, may have cold-start latency or downtime
- Stale data — index may not reflect real-time conditions if upstream data source is delayed
- Invalid or missing USDC balance — agent wallet lacks sufficient funds for $0.05 USDC call
