# List Config Schema Versions

`GET /config-schemas/`

Lists the simulation config schema versions currently supported for each market region: the current version and, during a release grace period, the previous (deprecated) one.

To fetch a schema document itself, call `GET /config-schemas/{market_region}/` for the latest, or `GET /config-schemas/{market_region}/{version}/` to pin a version. Use `?market_region=` to filter this list to a specific region.

## Query parameters

- `market_region` 'caiso' | 'ercot' | 'gb' | 'germany' | 'miso' | 'nem' | 'nyiso' | 'pjm' | 'spain'
- `limit` integer
- `offset` integer

## Response `200`

Paginated list of supported config schema versions.

  - `count` integer — Total number of results.
  - `next` unknown
  - `previous` unknown
  - `results` ConfigSchemaListItem[]
    - `api_version` string — The API version string for this schema. Pass this value (or just its major version, e.g. `1`) as `api_version` when submitting a run via `POST /runs/`.
    - `market_region` 'caiso' | 'ercot' | 'gb' | 'germany' | 'miso' | 'nem' | 'nyiso' | 'pjm' | 'spain' — The market region this schema applies to.
    - `status` 'current' | 'deprecated' — Whether this is the region's current schema or the previous (deprecated) one, still supported for a grace period after a new version is released.

## Other responses
