## Known failure modes

- Time window parameter malformed or out of supported range — returns validation error
- Grok API upstream outage causing delayed or missing sentiment data
- Rate limiting or payment failure via x402/USDC micropayment — returns 402 Payment Required
- Overly broad query returning noisy, low-signal sentiment aggregation
