Rows are ordered by relationship, then citing document and citation. A document can cite laws in legalRefs without any reference rows. Each returned reference costs $0.003; empty pages and failed requests are free. ## OpenAPI ````yaml /openapi.json get /insurance/regulatory-documents/{documentId}/references openapi: 3.0.3 info: title: Effective API version: 2.0.0 description: The public Effective REST API.
