# Curated SNB cube catalog

`GET /api/v1/snb/catalog`

Hand-curated index of SNB cubes exposed by the Sugra API. The SNB data portal does not publish a listing endpoint, so this catalog is maintained manually. Use `/api/v1/snb/cube/{cubeId}` to fetch any SNB cube not listed here.

## Response `200`

Curated list of SNB cubes with categories and frequencies.

- EnvelopeListSnbCatalogItem
  - `data` SnbCatalogItem[], required
    - `cube_id` string, required — SNB cube identifier.
    - `name` string, required — Human-readable cube name.
    - `category` string, required — Sugra category (rates, fx, inflation, money, balance-sheet, banking, external, property).
    - `frequency` string, required — Data frequency (daily, monthly, quarterly, annual).
    - `endpoint` string, required — Sugra API endpoint that exposes this cube.
  - `meta` SugraMeta, required — Metadata attached to every /api/v1/* response envelope.
    - `endpoint` string, required — Requested endpoint path.
    - `data_time` string, required — ISO 8601 UTC timestamp of the source data, not of the request.
    - `response_time` string, required — ISO 8601 UTC timestamp when this response was produced.
    - `provider` string, required — API name and version.
    - `source` string, nullable — Identifier of the primary upstream source used for this response.
    - `attribution` string, nullable — Human-readable attribution mandated by an upstream source (e.g. a securities regulator or self-regulatory organization). Present only on responses whose source requires the owner and source to be clearly identified. Do not remove or alter it when using the response.
    - `fallback_used` boolean, nullable — True when the primary source failed and a fallback produced the data.
    - `fallback_chain` string[], nullable — Ordered list of sources attempted, in the order they were tried.
    - `cached` boolean, nullable — True when this response was served from the internal cache.
    - `stale` boolean, nullable — True when the cached response was returned after the upstream rate-limited or errored. Clients can use this to detect degraded data.

## Other responses

- `401` — Missing or invalid `x-api-key` header.
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
