The /api/v1/ REST API gives full CRUD access to everything a staff member can do in the app: process serving and investigation cases, case notes and updates, documents, clients, billing (invoices, payouts, credit, retainers), quotes, time and expense tracking, and — for agencies with the Notary module enabled — signing clients, jobs, journal, documents, and invoices.
It's designed to be driven by an AI agent ("AI employee") as easily as by a human developer: JSON in, JSON out, one consistent auth header shape across the whole product, and a machine-readable OpenAPI schema at /api/v1/swagger.json.
