# List numscript versions

`GET /v3/{ledgerName}/numscripts/{name}/versions`

## Request

- Base URL: `http://localhost:9000`
- URL: `http://localhost:9000/v3/{ledgerName}/numscripts/{name}/versions`
- Auth: one of:
  - HTTP bearer
  - none

Returns the numscript's history: its current latest (greatest stored
semver) and every stored version, highest-first.

## Path parameters

- `ledgerName` string, required
- `name` string, required

## Headers

- `X-Consistency` 'linearizable' | 'stale'

## Response `200`

Numscript versions retrieved successfully

- ListNumscriptVersionsResponse
  - `data` object, required
    - `latestVersion` string: The current latest — the greatest stored semver
    - `versions` NumscriptVersionEntry[], nullable: Every stored version, highest-first
      - `version` string, required: Stored semver version string (e.g. "1.0.0")
      - `createdAt` string, date-time: When this version was stored (ISO 8601 format)

## Other responses

- `400`: Bad request
- `401`: Authentication required (missing or invalid JWT token)
- `403`: Insufficient permissions (missing required scope)
- `404`: Not found
- `405`: Method not allowed
- `500`: Internal server error
- `503`: Service unavailable — the server cannot serve the request right now but an immediate retry can succeed. The `errorCode` field discriminates the cause: `NO_LEADER` (no elected Raft leader), `CACHE_HORIZON_EXCEEDED` (admission snapshot too old, retry against a fresh one), `UNAVAILABLE` (an internal forwarded stream was torn down mid-transfer), or the reason of any domain error of the unavailable kind (e.g. `INDEX_BUILDING`).
