# Single instrument record from WMO OSCAR/Space

`GET /api/v1/environment/oscar-wmo/instruments/{id}`

Fetch a single instrument detail record by its URL-safe slug (e.g. `3mi`, `acrim_iii`, `modis`, `olci`). Returns instrument acronym, full name, type, WIGOS classification, providing agency, the list of satellites the instrument flies or flew on (with per-flight status), and the variables measured (derived from the variables -> instruments relationship). Attribution: WMO OSCAR/Space (World Meteorological Organization).

## Path parameters

- `id` string, required — Instrument slug as published upstream. Lowercase URL-safe identifier.

## Response `200`

Full instrument detail with nested satellite flights and measured variables.

- EnvelopeOscarInstrumentDetailPayload
  - `data` OscarInstrumentDetailPayload, required — Single instrument detail response.
    - `instrument` OscarInstrument, required — Single Earth-observation instrument record.
      - `instrument_id` integer, nullable — Upstream numeric instrument identifier. Informational only - not accepted as a path parameter upstream.
      - `slug` string, nullable — URL-safe slug (primary key for detail lookup).
      - `acronym` string, nullable — Short display name or acronym (e.g. `3MI`, `ACRIM-III`).
      - `fullname` string, nullable — Full descriptive instrument name.
      - `providing_agency` string, nullable — Agency or agencies providing this instrument.
      - `agency_name` string, nullable — First participating agency name. Convenience alias for filtering and display.
      - `instrument_type` string, nullable — Instrument type classification (`Moderate-resolution optical imager`, `Radar scatterometer`, etc.).
      - `classification` string[], nullable — 3-level classification path (Earth observation instrument - class - subclass).
      - `wigos_subcomponent` object, nullable — Nested WIGOS subcomponent classification tree.
      - `satellites` OscarInstrumentSatellite[], nullable — Satellites this instrument flies or flew on.
        - `start_date` string, nullable — Flight start date in upstream freeform notation.
        - `end_of_life` string, nullable — Flight end-of-life date in upstream freeform notation.
        - `status` string, nullable — Flight status on this satellite.
        - `satellite_id` integer, nullable — Upstream numeric satellite identifier. Informational only; use `satellite_slug` for detail lookups.
        - `satellite_slug` string, nullable — Satellite slug (URL-safe identifier) - resolves via `/satellites/{slug}`.
        - `satellite_name` string, nullable — Satellite acronym or short name.
        - `satellite_fullname` string, nullable — Full descriptive satellite name.
      - `measurements` string[], nullable — Variables measured by this instrument (slugs). Derived from the upstream variables -> instruments mapping.
    - `notes` string, nullable — Advisory notes about this response.
  - `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.
- `422` — Validation Error
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
