# Select standard or Paid performance database compute

`POST /v1/projects/{project_id}/database/compute`

## Request

- Base URL: `https://app.ohmyho.st`
- URL: `https://app.ohmyho.st/v1/projects/{project_id}/database/compute`
- Auth: HTTP bearer

Requires project-write access and explicit confirmation. Reads the organization plan at acceptance (Free 0.25 CU/1 GB/60 idle seconds or Paid 0.5 CU/2 GB/60 idle seconds). Changes the existing database in place without copying or resetting data. Shared Dev/Prod data changes both environments. A brief connection interruption is possible. Poll the returned operation every 60 seconds; do not submit a second change while it runs. Completion requires actual provider settings and settled operations. Actual CU consumption remains metered. Performance requires effective Paid access and an active rate; it selects fixed 1 CU/4 GB/300 idle seconds at 2.5 times Paid-standard database compute credits per equal active minute. Only database compute changes price. Raw CU-second measurements are preserved; mixed or uncertain transition hours waive the premium. Returning to standard restores the effective plan size.

## Path parameters

- `project_id` string, required

## Headers

- `X-Request-Id` string
- `Idempotency-Key` string, required

## Request body

- object
  - `environment` 'dev' | 'prod', required
  - `profile` 'standard' | 'performance', required
  - `confirm` true, required

## Response `202`

The mutation was accepted for asynchronous processing.

- Operation: Durable record returned for an accepted asynchronous mutation. Optional reconciliation is a current observation for queued/running work, separate from immutable terminal state. A completed reconciliation attempt alone does not mean the operation succeeded.
  - `blocking_operation_id` string
  - `deployment_id` string
  - `id` string, required
  - `state` 'queued' | 'running' | 'succeeded' | 'failed' | 'cancelled', required
  - `created_at` string, date-time, required
  - `updated_at` string, date-time, required
  - `result` object
  - `error` OperationFailure
    - `code` 'operation_failed' | 'operation_abandoned' | 'authorization_changed' | 'source_commit_conflict' | 'source_snapshot_invalid' | 'source_upload_expired' | 'recovery_dispatch_failed' | 'recovery_job_failed' | 'recovery_input_expired' | 'recovery_database_unavailable' | 'recovery_checksum_mismatch' | 'recovery_scope_unavailable' | 'recovery_archive_too_large' | 'build_not_started' | 'build_failed' | 'database_write_rejected' | 'database_write_unavailable' | 'database_write_outcome_unknown' | 'database_compute_failed' | 'database_compute_plan_changed' | 'database_compute_rejected' | 'database_migration_failed' | 'insufficient_organization_credits' | 'paid_plan_required' | 'runtime_candidate_failed' | 'runtime_candidate_rejected' | 'storage_jurisdiction_conflict' | 'provider_state_absent' | 'auto_deploy_plan_rejected' | 'promotion_source_stale' | 'promotion_target_stale', required
    - `message` string, required
    - `retryable` false, required: A terminal operation cannot be retried in place; follow suggested_action.
    - `suggested_action` string, required
    - `detail` string: Present only on auto_deploy_plan_rejected when planning the pushed commit returned a typed refusal. It is the same fixed catalog sentence that the planning 409 problem returns as detail, naming the file, the rule and the required change.
  - `progress` OperationDeploymentProgress: Current deployment dependency observation, separate from immutable operation history. Poll the same operation; mail readiness does not mean application activation.
    - `build_completed_at` string, date-time: Actual successful build completion time when this operation ran a build; omitted for reused artifacts without a current build.
    - `phase` 'queued' | 'building' | 'publishing' | 'waiting_for_mail' | 'mail_status_unavailable', required
    - `project_id` string, required
    - `deployment_id` string, required
    - `observed_at` string, date-time, required
    - `next_poll_after_seconds` 60, required
    - `suggested_action` string, required
  - `reconciliation` OperationReconciliation
    - `state` 'required' | 'pending', required
    - `attempt_id` string, required
    - `observed_at` string, date-time, required
    - `suggested_action` string, required
