Each result is one company's row in one year's directory: NIT, name, rank, CIF (imports) or FOB (exports) value in US dollars, net weight, declarations or declaration items, and its main subpartidas arancelarias. Newest year first, then by value. Served by Croma (`as_of` says how current the data is), brought up to date weekly. **Dataset endpoint**: answers from the whole source in milliseconds and carries `as_of`. ## OpenAPI ````yaml /api-reference/openapi.json post /co/dian-trade/directory-search/v1 openapi: 3.1.0 info: title: Croma Marketplace API version: 1.0.0 description: >- Government-data APIs for Colombia, Peru, Mexico, and 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: tomas@usecroma.com servers: - url: https://api.croma.run security: [] paths: /co/dian-trade/directory-search/v1: post: tags: - Colombia - DIAN Importers and Exporters summary: DIAN Importers and Exporters Search description: >- Search DIAN's directories of importers and exporters of goods, every year since 2017 and both directories at once: by company name (`query`), `flow` (`import` or `export`), `year`, and `tariff_code` (a 4-digit heading, 6-digit HS subheading or 10-digit subpartida among each company's five main ones).

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_…).
