`GET /api/{projectId}/dsp/{dspId}`

## Request

- Base URL: `https://studio.edgeimpulse.com/v1`
- URL: `https://studio.edgeimpulse.com/v1/api/{projectId}/dsp/{dspId}`
- Auth: one of:
  - API key in header `x-api-key`
  - API key in cookie `jwt`
  - API key in header `x-jwt-token`
  - OAuth 2
    - Authorization code: `/v1/oauth/authorize`
    - Client credentials
    - Implicit: `/v1/oauth/authorize`
    - Password
    - Token URL: `/v1/oauth/token`
- TypeScript: <https://skmtc.dev/edgeimpulse/apis/edge-impulse-api/docs/api/:projectId/dsp/:dspId/get.ts> (a function with typed inputs; its response is checked against the schema)

Retrieve the configuration parameters for the DSP block. Use the impulse functions to retrieve all DSP blocks.

## Path parameters

- `projectId` integer, required
- `dspId` integer, required

## Response `200`

OK

      - `generated` boolean, required: Whether this block has generated features
      - `count` integer: Number of generated features
      - `labels` string[]: Names of the features
      - `classes` string[]: Classes that the features were generated on
