Context

The SerpAPI response cache TTL is hardcoded to 24 hours in config.py. Operators cannot tune cache freshness without modifying code.

What to do

  • Add SERP_CACHE_TTL_HOURS to config.py with a default of 24.
  • Update the cache logic to read SERP_CACHE_TTL_HOURS from config.
  • Document the variable in .env.example.

Acceptance criteria

  • Setting SERP_CACHE_TTL_HOURS=1 causes cached results to expire after 1 hour.
  • The default of 24 hours is preserved when the variable is not set.

Roadmap reference: P2 Backend — SERP cache TTL is hardcoded.
