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: /sv/cnr-sv/company/v1: post: tags: - El Salvador - Centro Nacional de Registros (CNR) summary: El Salvador Company Filings by File Number description: >- Retrieve every filing of one company at El Salvador's Registro de Comercio by its file number (N° de expediente, e.g. `2026136080`, as `file_number` in a search result): its commercial registration and any transfer or cancellation, plus the balance sheets and corporate acts the bulletin publishes under its legal name, newest first, with `cancelled` saying whether the registration was cancelled. **Dataset endpoint**: answers from the whole source in milliseconds and carries `as_of`. operationId: cnr_sv_company parameters: - $ref: '#/components/parameters/IdempotencyKey' requestBody: required: true content: application/json: schema: type: object required: - file_number properties: file_number: type: string minLength: 1 maxLength: 20 description: >- The company's registration file number (N° de expediente) at the Registro de Comercio, e.g. `2026136080`, as `file_number` in a search result. additionalProperties: false example: file_number: '2026136080' responses: '200': description: Successful response headers: X-Request-Id: $ref: '#/components/headers/X-Request-Id' RateLimit-Policy: $ref: '#/components/headers/RateLimit-Policy' Idempotency-Key: $ref: '#/components/headers/Idempotency-Key' Deprecation: $ref: '#/components/headers/Deprecation' Sunset: $ref: '#/components/headers/Sunset' X-RateLimit-Limit: $ref: '#/components/headers/X-RateLimit-Limit' X-RateLimit-Remaining: $ref: '#/components/headers/X-RateLimit-Remaining' X-RateLimit-Reset: $ref: '#/components/headers/X-RateLimit-Reset' X-Cache: $ref: '#/components/headers/X-Cache' content: application/json: schema: $ref: '#/components/schemas/CnrSvCompanyResponse' '400': description: Invalid request body headers: X-Request-Id: $ref: '#/components/headers/X-Request-Id' RateLimit-Policy: $ref: '#/components/headers/RateLimit-Policy' Idempotency-Key: $ref: '#/components/headers/Idempotency-Key' Deprecation: $ref: '#/components/headers/Deprecation' Sunset: $ref: '#/components/headers/Sunset' content: application/json: schema: $ref: '#/components/schemas/ApiError' '401': description: Missing or invalid API key headers: X-Request-Id: $ref: '#/components/headers/X-Request-Id' RateLimit-Policy: $ref: '#/components/headers/RateLimit-Policy' Idempotency-Key: $ref: '#/components/headers/Idempotency-Key' Deprecation: $ref: '#/components/headers/Deprecation' Sunset: $ref: '#/components/headers/Sunset' content: application/json: schema: $ref: '#/components/schemas/ApiError' '429': description: Rate limit exceeded headers: X-Request-Id: $ref: '#/components/headers/X-Request-Id' RateLimit-Policy: $ref: '#/components/headers/RateLimit-Policy' Idempotency-Key: $ref: '#/components/headers/Idempotency-Key' Deprecation: $ref: '#/components/headers/Deprecation' Sunset: $ref: '#/components/headers/Sunset' X-RateLimit-Limit: $ref: '#/components/headers/X-RateLimit-Limit' X-RateLimit-Remaining: $ref: '#/components/headers/X-RateLimit-Remaining' X-RateLimit-Reset: $ref: '#/components/headers/X-RateLimit-Reset' Retry-After: $ref: '#/components/headers/Retry-After' content: application/json: schema: $ref: '#/components/schemas/ApiError' '500': description: Internal error headers: X-Request-Id: $ref: '#/components/headers/X-Request-Id' RateLimit-Policy: $ref: '#/components/headers/RateLimit-Policy' Idempotency-Key: $ref: '#/components/headers/Idempotency-Key' Deprecation: $ref: '#/components/headers/Deprecation' Sunset: $ref: '#/components/headers/Sunset' content: application/json: schema: $ref: '#/components/schemas/ApiError' '502': description: Upstream source returned an error headers: X-Request-Id: $ref: '#/components/headers/X-Request-Id' RateLimit-Policy: $ref: '#/components/headers/RateLimit-Policy' Idempotency-Key: $ref: '#/components/headers/Idempotency-Key' Deprecation: $ref: '#/components/headers/Deprecation' Sunset: $ref: '#/components/headers/Sunset' content: application/json: schema: $ref: '#/components/schemas/ApiError' security: - bearerAuth: [] externalDocs: description: Interactive documentation and examples url: https://docs.usecroma.com/guides/el-salvador/cnr components: parameters: IdempotencyKey: name: Idempotency-Key in: header required: false description: >- Optional client-chosen key for this request (any string up to 255 characters, e.g. a UUID). 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_…).
