API · Exit · Parachute Analyses
Create a parachute analysis.
Open a structured ParachuteAnalysis for a target CorporateTransaction. The body carries the tax-counsel-supplied list of disqualified individuals under IRC §280G(c) (officers in the top-50 / 10% rule, 1%+ shareholders, top-1% / top 250 highest-paid employees). The analysis starts in status: draft and carries no parachute breakdown until POST /parachute_analyses/{id}/compute runs.
Returns 202 Accepted. On completion, emits parachute_analysis.created. Subscribe via `POST /v1/webhook_endpoints`. Idempotent via Idempotency-Key.
