# DELETE /projects/{project_id}

`DELETE /projects/{project_id}`

## Request

- Base URL: `https://api.primitive.dev/v1`
- URL: `https://api.primitive.dev/v1/projects/{project_id}`
- Auth: HTTP bearer

Requires a current human organization membership. Machine credentials are refused. Results are scoped to current project access. No local paths or existing conversation history are shared.

## Path parameters

- `project_id` string, uuid, required

## Query parameters

- `version` integer, required

## Response `200`

Success

- object
  - `success` true, required
  - `data` ProjectsDeleteProjectResult, required
    - `deleted` true, required

## Other responses

- `400`: Invalid request parameters
- `401`: Invalid or missing API key
- `403`: Authenticated caller lacks permission for the operation
- `404`: Resource not found
- `409`: The request conflicts with the current state of the resource
- `429`: Rate limit exceeded. The `ratelimit-*` headers describe the limiter that rejected this request, with its own limit and window, not the API budget that successful responses report. A limiter that reports only a wait sends `Retry-After` alone.
- `503`: directory_limit: the organization agent directory is larger than projects can read. Narrow the directory before retrying.
