> API Reference / Endpoints / Create compute endpoint

## POST /projects//endpoints

Creates a compute endpoint for the specified branch.
A compute endpoint is a Neon compute instance.
There is a maximum of one read-write compute endpoint per branch.
If the specified branch already has a read-write compute endpoint, the operation fails.
A branch can have multiple read-only compute endpoints.

For more information about compute endpoints, see [Manage computes](/guides/manage-operate-manage-computes).

### Parameters

- `project_id` (string, path, required)
  The Neon project ID

### Request body

- `endpoint` (object, required)
  Configuration for the compute endpoint to create.
  - `branch_id` (string, required)
    The ID of the branch the compute endpoint will be associated with

  - `region_id` (string, optional)
    The region where the compute endpoint will be created. Only the project's `region_id` is permitted.

  - `type` (string, required)
    Compute endpoint type. `read_write`: the primary read-write endpoint (one per branch). `read_only`: a read replica endpoint (multiple allowed per branch).
    Possible values: `read_only`, `read_write`

  - `settings` (object, optional)
    A collection of settings for a compute endpoint
    - `pg_settings` (object, optional)
      A raw representation of Postgres settings

    - `pgbouncer_settings` (object, optional, deprecated)
      Deprecated. PgBouncer settings for the compute endpoint. Removal scheduled for June 20, 2026.

    - `preload_libraries` (object, optional)
      The shared libraries to preload into the project's compute instances.

      - `use_defaults` (boolean, optional)
        When true, the project's preload libraries include the platform default set in addition to any libraries listed in `enabled_libraries`.
      - `enabled_libraries` (array, optional)
        Names of shared preload libraries to enable for the project.

  - `autoscaling_limit_min_cu` (number, optional)
    The minimum number of Compute Units. The minimum value is `0.25`.
    See [Compute size and Autoscaling configuration](/guides/manage-operate-manage-computes#compute-size-and-autoscaling-configuration)
    for more information.

  - `autoscaling_limit_max_cu` (number, optional)
    The maximum number of Compute Units.
    See [Compute size and Autoscaling configuration](/guides/manage-operate-manage-computes#compute-size-and-autoscaling-configuration)
    for more information.

  - `provisioner` (string, optional)
    Compute provisioner. `k8s-neonvm` (default) supports Autoscaling; `k8s-pod` is fixed-size compute. Also `docker` and `serverless-platform`.

  - `pooler_enabled` (boolean, optional, deprecated)
    Deprecated. To enable connection pooling, append `-pooler` to the endpoint ID in the connection string.
    See [How to use connection pooling](/guides/postgres-connect-connection-pooling#how-to-use-connection-pooling)

  - `pooler_mode` (string, optional, deprecated)
    Deprecated. The connection pooler mode. Removal scheduled for June 20, 2026.

    Possible values: `transaction`

  - `disabled` (boolean, optional)
    Whether to restrict connections to the compute endpoint.
    Enabling this option schedules a suspend compute operation.
    A disabled compute endpoint cannot be enabled by a connection or
    console action. However, the compute endpoint is periodically
    enabled by check\_availability operations.

  - `passwordless_access` (boolean, optional)
    NOT YET IMPLEMENTED. Whether to permit passwordless access to the compute endpoint.

  - `suspend_timeout_seconds` (integer, optional, format: int64)
    Scale-to-zero idle timeout, in seconds, before the compute suspends. `0` uses the plan default; `-1` disables scale-to-zero (never suspends). Minimum is plan-dependent (Scale: 60); maximum 604800 (one week). Free cannot change it; Launch can only enable or disable; Scale can set any value.

  - `name` (string, optional)
    Optional name of the compute endpoint

### Errors

**default**
General Error.

The request may or may not be safe to retry, depending on the HTTP method, response status code,
and whether a response was received.

- If no response is returned from the API, a network error or timeout likely occurred.
- In some cases, the request may have reached the server and been successfully processed, but the response failed to reach the client. As a result, retrying non-idempotent requests can lead to unintended results.

The following HTTP methods are considered non-idempotent: `POST`, `PATCH`, `DELETE`, and `PUT`. Retrying these methods is generally **not safe**.
The following methods are considered idempotent: `GET`, `HEAD`, and `OPTIONS`. Retrying these methods is **safe** in the event of a network error or timeout.

Any request that returns a `503 Service Unavailable` response is always safe to retry.

Any request that returns a `423 Locked` response is safe to retry. `423 Locked` indicates that the resource is temporarily locked, for example, due to another operation in progress.

- `request_id` (string, optional)
  Unique identifier for the request, useful for debugging.
  You can set this value manually by including an `X-Request-ID` header in the request. If not provided, the value will be generated automatically.

- `code` (string, required)
  Machine-readable code classifying the error type. See `message` for a human-readable explanation.
  Default: \`\`

- `message` (string, required)
  Error message
