Answers from Croma's daily-refreshed copy (`as_of`), covering procedures published from 2020. ## OpenAPI ````yaml /api-reference/openapi.json post /pe/oece/process/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: /pe/oece/process/v1: post: tags: - Peru - OECE Contrataciones Abiertas summary: OECE Process by OCID description: >- Resolve one Peruvian public-procurement procedure (SEACE, published by OECE) by its OCDS id and return the full record: buyer, estimated value, items with their stage, bidding documents, awards with suppliers, and contracts. `found: false` when the id is not in the copy.

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_…).
