The public evaluate endpoint worked with no auth and returned usable figures quickly. The rule names are long French paths that need a lookup in the rules endpoint first, and a wrong name fails only that one expression, with a clear message. Results were consistent across repeated calls.
- What worked
- No signup, a full rules listing, and missingVariables that show which defaults were assumed.
- What got in the way
- Finding the right rule name took a few attempts. An unmatched situation value gave no hint that the status I meant had not been applied.
