# Get Macro Catalog

`GET /api/v1/macro/catalog`

Return all supported macro series with full policy metadata.
No FRED API call. Always fast.

Each entry includes: unit_type, supported_transforms, default_transforms,
default_last_n, max_last_n, and cache TTL policy.

## Response `200`

FRED macro series catalog with country, section, units, and frequency metadata.

- EnvelopeMacroCatalogResponse
  - `data` MacroCatalogResponse, required — Response shape for GET /api/macro/catalog.
    - `catalog` MacroCatalogEntry[], required — Catalog listing.
      - `country` string, required — Country code or name.
      - `section` string, required — Catalog section identifier.
      - `path` string, required — API path for this series.
      - `fred_series_id` string, required — FRED series identifier.
      - `title` string, required — Display title.
      - `units` string, required — Units of measure.
      - `frequency` string, required — Observation frequency (daily, weekly, monthly, quarterly, annual).
      - `seasonal_adjustment` string, required — Seasonal adjustment label from FRED.
      - `unit_type` string, required — Catalog unit_type.
      - `cache_ttl_seconds` integer, required — Cache TTL in seconds.
      - `default_mode` string, required — Default query mode for this series.
      - `default_last_n` integer, required — Default number of observations returned.
      - `max_last_n` integer, required — Maximum last_n cap.
      - `default_transforms` string[], required — Default transforms applied.
      - `supported_transforms` string[], required — Supported transform names.
    - `meta` MacroCatalogMeta, required
      - `version` string, required — Version identifier.
      - `count` integer, required — Number of items in this result set.
  - `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. JSON body with a stable `code` distinguishing `missing_api_key` (no header sent) from `invalid_api_key` (header sent, key not accepted); any other 401 source carries the generic `unauthorized` with its detail as `reason`. Plus `hint`. `plan` is always null on 401 - an unauthenticated request has no plan; quota exhaustion is 429, not 401.
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
