Stable, versioned access to Montenegro business, procurement and government data with a public OpenAPI contract.
Public GET endpoints live under /v1. Breaking client changes receive a new major version; the OpenAPI document is the machine-readable contract.
The catalog documents source, cadence, keys, methodology and limitations. Responses retain source URLs and dates where publishers provide them.
Reasonable public reading is available without a key. Higher volume, webhooks, SLAs, snapshots and commercial redistribution require a separate agreement.
