To continue, pass `nextCursor` as `cursor` with the same `maxBytes`. Documents are updated in place: if `textRevision` changes, start again without a cursor. Returns 409 `text_unavailable` when the document has no text; download its source file instead. Each nonempty chunk costs $0.01, including repeats; failed requests are free. ## OpenAPI ````yaml /openapi.json get /insurance/regulatory-documents/{documentId}/text openapi: 3.0.3 info: title: Effective API version: 2.0.0 description: The public Effective REST API.
