`GET /api/v1/un-sdg/indicators`

All 251 indicators in the SDG global monitoring framework, with IAEG-SDG tier classification (Tier 1 = established methodology + data, Tier 2 = methodology but limited data, Tier 3 = methodology under development). Source: `/Indicator/List`. Cached 24 hours.

## Response `200`

SDG indicators with code, description, tier, and parent goal/target.

- EnvelopeSdgIndicatorsPayload
  - `data` SdgIndicatorsPayload, required
    - `indicators` SdgIndicator[], required — SDG indicators with IAEG-SDG tier classification (251 total).
      - `code` string, nullable — Indicator code (e.g. '1.1.1').
      - `description` string, nullable — Full indicator description from the IAEG-SDG framework.
      - `tier` string, nullable — IAEG-SDG tier classification: '1' (established methodology + data), '2' (established methodology, limited data), '3' (methodology under development).
      - `uri` string, nullable — Upstream URI fragment.
      - `goal_code` string, nullable — Parent goal code.
      - `target_code` string, nullable — Parent target code.
    - `count` integer, required — Number of indicators returned.
  - `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.
