# Generic OCR

> Run OCR on any image with the Dojah Generic OCR service and get back the raw text it contains, line by line.

<div className="dj-endpoint">
  <span className={`dj-method dj-method-post`}>POST</span>
  <code>/api/v1/ml/ocr/generic</code>
</div>

Run optical character recognition on any image and get back the raw text it contains, line by line — useful when you need the text off a document the structured endpoints don’t cover.

## Headers

| Header          | Required | Description                                         |
| --------------- | -------- | --------------------------------------------------- |
| `Authorization` | Yes      | Your app's secret key, sent as-is — *not* `Bearer`. |
| `AppId`         | Yes      | The App ID from your dashboard.                     |
| `Content-Type`  | Yes      | `application/json`                                  |

## Body parameters

| Parameter | Type   | Required | Description                                                                                          |
| --------- | ------ | -------- | ---------------------------------------------------------------------------------------------------- |
| `img`     | string | Yes      | Base64 value of the image. **Do not** include the data-type prefix (e.g. `data:image/jpeg;base64,`). |

## Response

A `200` returns `entity.data` — an array of the text fragments detected in the image, in reading order. The example below is trimmed; the live response returns every line.

## Errors

| Code  | Meaning                                                                                       |
| ----- | --------------------------------------------------------------------------------------------- |
| `400` | Bad request — a required field is missing or the image can't be read.                         |
| `401` | Unauthorized — check your key and `AppId` (no `Bearer` prefix).                               |
| `402` | Insufficient wallet balance. [Fund your wallet](/api-reference/core-concepts/wallet-billing). |
| `424` | Failed dependency — the analysis engine couldn't process the document.                        |
| `429` | Too many requests — back off and retry.                                                       |
