Useful for trading bots or portfolio agents that need a sentiment gate before executing trades.

## Known failure modes

- Payment not completed via x402 protocol — returns 402 Payment Required
- API server downtime or rate limiting — returns 5xx error
- Upstream data provider unavailable — may return stale or empty data
- Malformed response if the underlying index source is unreachable

OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana and Algorand via x402.

## Output
