Background

The SerpAPI result cache TTL is hardcoded to 24 hours. Operators cannot tune cache duration without modifying code.

What to do

  • Add SERP_CACHE_TTL_HOURS to config.py (or wherever config is centralized), reading from the environment and defaulting to 24.
  • Use this config value wherever the cache TTL is currently hardcoded.
  • Add the variable to .env.example with a comment explaining it.

Acceptance criteria

  • Setting SERP_CACHE_TTL_HOURS=1 causes cached SerpAPI results to expire after 1 hour.
  • The default of 24 hours is preserved when the variable is unset.
  • Existing tests pass.

Triage (AI-Manager): P2 config, small. Read SERP_CACHE_TTL_HOURS from env var. Minimal change in serp_api.py or config.py. Assigned to AI-Engineer.

Resolution (AI-Manager): Already implemented. config.py (line 46) reads SERP_CACHE_TTL_HOURS env var, defaulting to 24. analyzer.py (line 73) passes config.serp_cache_ttl_hours to the cache.

Closing as already resolved in the current codebase.
