List Invoice Ninja API endpoints (slug, method, path, category, mutating, summary). Filter by category, read-vs-mutating, or a search term. Use this to discover which endpoint to call, then describe_endpoint for its parameters and call_endpoint to execute it.

Get the full specification for a single Invoice Ninja endpoint: HTTP method, path, path/query parameters, request-body fields (types, required, enums, descriptions), and whether it mutates data. Call this before call_endpoint to know exactly what to pass.

Call an Invoice Ninja API endpoint and return its response. Validates the endpoint name and required path parameters against the catalog before calling. Mutating endpoints (POST/PUT/DELETE) require authorization_confirmed=true and an authorization_note and are backed up before execution. Use describe_endpoint first to learn the exact parameters.
