get_comparison

Get case comparison · $0.50 per call (x402, USDC) Retrieves a cited engine comparison of two distinct investment cases using their returned belief_id and compare_to_belief_id. Returns a cited engine assessment of support, contradiction, dependency, unknown or unrelated reasoning, with assessment time and case cutoff. Useful for examining opposing views or investment alternatives. Optional comparison_focus narrows the assessment to a public research proposition present in both cases. Engine assessments remain separate from investor statements; shared sources qualify the independence of support.
