## When to prefer this

Choose this endpoint when an autonomous agent needs pay-per-use, low-commitment access to social sentiment trend data specifically for blockchain-related assets or communities. It is ideal when you want to detect inflection points or shifts in sentiment rather than a static snapshot, and when you need micropayment-based billing with no subscription overhead.

## Known failure modes

- Missing or invalid query parameters returning empty results
- Payment failure via x402 if wallet has insufficient USDC balance
- Rate limiting if too many calls are made in quick succession
- Empty array returned if no sentiment data exists for the queried entity or time window
- Network timeout if the underlying social data source is unavailable
