# List databases

`GET /projects/{project_id}/branches/{branch_id}/databases`

Retrieves a list of databases for the specified branch. A branch can have multiple databases. For related information, see [Manage databases](/guides/manage-operate-manage-databases).

Tool: `inspect_database`

Reach for this first when asked why a database is slow, large, bloated, or behind. It runs one predefined, read-only Postgres diagnostic against a Neon branch — pick the one that answers the question from the `check` parameter's list, instead of writing catalog SQL by hand. These are the same checks as the `neon inspect db` CLI command.

Not for: arbitrary SQL (`run_sql`), the slowest queries by average execution time with your own threshold and limit (`list_slow_queries`), the plan of one statement (`explain_sql_statement`), applying an optimization (`prepare_query_tuning`), compute and Neon Function logs (`query_logs`), or listing tables and columns (`get_database_tables`, `describe_table_schema`). Several checks read alike and are not: `long-running-queries` is what is running right now in the inspected database and has been for over five minutes; `stalled-queries` is a compute-wide snapshot of active queries running longer than 30 seconds with parallel-worker grouping, waits, and blockers; `outliers` is cumulative execution time since statistics were last reset; and `calls` is call frequency over that same history. Omit `databaseName` to run a database-scoped check against every database on the branch. The result adds a `database` column. `stalled-queries`, `lfc-hit-rate`, `working-set`, and `replication-slots` are compute-wide: they run once against the first listed database. For `lfc-hit-rate` and `working-set`, cache counters reset when the compute restarts. One failing database fails the whole run. `bloat` is a statistical estimate, not a measurement. When a check needs an extension that is not installed, the tool says so and names the `CREATE EXTENSION` statement. Installing it writes to the user's database — ask before running it.

- `check` (enum, required)
  Which diagnostic to run:
- `projectId` (string, required)
  The ID of the project to inspect
- `branchId` (string, optional)
  An optional ID of the branch. If not provided the default branch is used.
- `databaseName` (string, optional)
- `computeId` (string, optional)
  The ID of the compute/endpoint. If not provided, the read-write compute associated with the branch will be used.
- `limit` (number, optional)
  Maximum number of rows to return from the combined result. Per-database ranking and SQL caps are applied first. The response reports how many rows the check produced and whether they were truncated, so raise this only when `truncated` is true. A few checks are capped in SQL and say so in their description.

## Errors

default

General error

This endpoint can return the standard Neon API error response.

Response fields

- `message` Required. Human-readable error message.
- `code` Required. Machine-readable error code.
- `request_id` Optional. Request identifier for debugging. You can provide one with the `X-Request-ID` header.

Retry guidance

If no response is returned, the request may still have reached the server. This is why retry safety depends on the method and status code.

Idempotent methods (`GET`, `HEAD`, `OPTIONS`) are generally safe to retry after a network error or timeout. Non-idempotent methods (`POST`, `PATCH`, `DELETE`, `PUT`) can change state, so avoid automatic retries unless your workflow can tolerate duplicate effects.

Responses with `423 Locked` or `503 Service Unavailable` are safe to retry. `423 Locked` means the resource is temporarily locked, usually because another operation is in progress.
