All inputs optional: pass `latitude` + `longitude` (with optional `radius_km`, default 10) for nearby cameras nearest first, or `type` (`nivel`, `cielo`, `deprimido`, `capa_limite`) to keep one kind. ## OpenAPI ````yaml /api-reference/openapi.json post /co/siata-geoportal/cameras/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/siata-geoportal/cameras/v1: post: tags: - Colombia - SIATA summary: SIATA Cameras description: >- SIATA's camera network in the Aburrá Valley (Medellín metropolitan area), about 90 cameras pointed at river gauges, the sky, underpasses and the boundary layer, each with the URL of its latest snapshot.

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_…).
