# Get deployment parameters

> Enumerate the available gateways, runtime engines, and instance types for deployment creation.

<Info>
  * The API server is `https://api.coreweave.com`.
  * Replace `{API_ACCESS_TOKEN}` with your [CoreWeave API access token](/security/authn-authz/manage-api-access-tokens).
  * For required permissions, see [IAM Access Policies](/security/iam/access-policies).
</Info>

The response includes:

* `gatewayIds`: gateway IDs in the caller's organization
  that can be referenced by a new deployment.
* `runtimeParameters.runtimeVersions`: map keyed by engine
  name; each entry lists the available version strings.
* `runtimeParameters.runtimeConfigOptions`: map keyed by
  engine name; each entry lists the engine-specific config
  keys allowed under `runtime.engineConfig`.
* `resourceParameters.instanceTypes`: instance types
  available for deployment.
