The text comes back a character range at a time (`offset`, `limit`); follow `next_offset` until `has_more` is false. **Dataset endpoint**: answers from the whole source in milliseconds and carries `as_of`. ## OpenAPI ````yaml /api-reference/openapi.json post /cl/tta/ruling/v1 openapi: 3.1.0 info: title: Croma Marketplace API version: 1.0.0 description: >- Government-data APIs for Colombia, Peru, Mexico, United States, Brazil, El Salvador, Bolivia, Japan, and Chile, plus global web search. Croma normalizes public-sector data into structured JSON for product teams and AI agents. Every operation is a POST with a JSON body and an organization API key as a bearer token; every operation is an idempotent lookup and accepts an optional `Idempotency-Key` header. Paths carry their major version (`/v1`); the versioning and deprecation policy, including the `Deprecation` and `Sunset` headers a retiring endpoint sends, is at https://docs.usecroma.com/versioning. Rate limits are per organization and reported on every response (`RateLimit-Policy`, `X-RateLimit-*`): https://docs.usecroma.com/rate-limits. termsOfService: https://usecroma.com/en/terms contact: name: Croma support url: https://usecroma.com/en/support email: support@usecroma.com servers: - url: https://api.croma.run security: [] paths: /cl/tta/ruling/v1: post: tags: - Chile - Tribunales Tributarios y Aduaneros (Chile) summary: TTA Ruling description: >- Retrieve one sentencia of Chile's Tribunales Tributarios y Aduaneros by its `id` from a search result: the case's RUC and RIT, caption, court, office, procedure, subject, dates, the court's extract, whether it is published as jurisprudence, Croma's copy of the signed PDF, and the sentencia's text.

Every Croma operation is an idempotent lookup: repeating a request with the same body returns the same result and creates nothing, so retrying after a timeout or network failure is always safe. The key is echoed back in the `Idempotency-Key` response header so you can correlate a retry with its first attempt. Each attempt that reaches the API counts against the rate limit. schema: type: string maxLength: 255 example: 0f8e9a42-6b7c-4d1e-9a3f-2c5d7e8f9a0b headers: X-Request-Id: description: Unique id for the request (req_…).
