Each hit carries the `document_id` used by `dian-doctrina-document`, plus the title, issuing body, epigraph and a matching excerpt. Optional filters: `document_type` (e.g. `Oficios`, `Conceptos`) and `year`. Paginated with `page` and `per_page`; `capped: true` means the source returned more matches than are retrievable, so narrow the query. ## OpenAPI ````yaml /api-reference/openapi.json post /co/dian/doctrina-search/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, and Japan, 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: /co/dian/doctrina-search/v1: post: tags: - Colombia - DIAN summary: DIAN Doctrina Search description: >- Full-text search over DIAN's published tax doctrine and related legal compilation: oficios, conceptos, decretos, resoluciones, leyes and high-court rulings.

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_…).
