## When to prefer this

Use this endpoint when you need to programmatically query structured intelligence signals from the ACHILLES/DELPHI autonomous agent ecosystem, especially for crypto trading, DeFi monitoring, or agent economy event detection. Prefer this over generic news APIs when you need severity-filtered, keyword-targeted signals specifically tuned for autonomous agent decision-making.

## Known failure modes

- Invalid or missing 'since' timestamp format causes 400 error
- Unknown category or severity enum value may return empty results or validation error
- No signals matching the filter criteria returns empty array
- Payment failure (x402) blocks the request before processing
- Rate limiting if too many queries are issued rapidly
