Shared response handling
Most routes return JSON and expose enough error detail to separate invalid input from upstream failures or assumption-driven calculation issues.
Live upstream data
The platform mixes deterministic local-data endpoints with a few upstream-backed routes, but all responses stay no-store to preserve freshness.
Route-level documentation
Each route family has a dedicated page covering request shape, response payload, assumptions, and common failure cases.
