# Get device calibration data

`GET /devices/{device_qrn}/calibrations`

## Request

- Base URL: `https://api-v2.qbraid.com/api/v1`
- URL: `https://api-v2.qbraid.com/api/v1/devices/{device_qrn}/calibrations`
- Auth: API key in header `X-API-KEY`

Retrieve the latest calibration snapshot for a device: qubit-level (T1, T2, frequency, readout/gate errors) and edge-level (two-qubit gate errors, gate lengths).

## Path parameters

- `device_qrn` string, required

## Response `200`

Success.

- GetDeviceCalibrationsResponse
  - `success` boolean, required
  - `data` DeviceCalibration, required
    - `_id` string
    - `deviceQRNs` string[], required
    - `provider` string, required
    - `lastCalibrated` string, date-time, required
    - `fetchedAt` string, date-time, required
    - `qubits` object, required: Qubit-level properties keyed by qubit index (string).
    - `edges` object, required: Edge-level properties keyed by metric name, then by source-qubit key, to a list of edge entries.
    - `createdAt` string, date-time
    - `updatedAt` string, date-time

## Other responses

- `400`: Invalid or missing QRN.
- `404`: Calibration data not found for this device.

## Changes

- **2026-11-03** `20848d926124`: 1 info
