FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
To use Composer is sometimes complicated. Especially for beginners.
Composer needs much resources. Sometimes they are not available on a simple webspace.
If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Please rate this library. Is it a good library?

Yandex Cloud Vision OCR PHP Client

HTTP client for Yandex Cloud Vision OCR (sync + async). Designed as a small, predictable, PSR-friendly Composer library with clear errors, DTOs, and optional concurrency via a runner interface.

Features

Sync OCR (recognizeText)
Async OCR (startTextRecognition + polling with wait / waitMany)
PSR-18 transport + PSR-17 factories
Deterministic DTOs with raw payload/meta
Typed exceptions
No hard dependency on event loops (optional concurrency via runner)

Requirements

PHP 8.4+
PSR-18 HTTP client
PSR-17 factories

Installation

You must also install a PSR-18 client and PSR-17 factories, for example:

Authentication

Two options:

IAM Token
Use Authorization: Bearer <IAM_TOKEN>.
API Key
Use Authorization: Api-Key <API_KEY> (no folderId header).

This library only signs requests and forwards headers; it does not call IAM endpoints.

Quick Start (Sync)

Async OCR (Start + Poll)

Options

Every OCR call accepts an OcrOptions object:

languageCodes (array of LanguageCode enums)
model (OcrModel enum, default is page)
requestId (string, forwarded as x-request-id)

Concurrency (waitMany)

waitMany() uses a runner to execute waits. Default is sequential:

You can provide a custom runner that performs concurrent execution.

Multi-page Documents

For some multi-page OCR responses, the API may return NDJSON/JSONL (one JSON object per line, one line per page).
The client parses this automatically and returns:

Error Handling

Exceptions are thrown for common failures:

ApiException — non-2xx responses or operation errors
HttpException — transport failures
ValidationException — invalid input or JSON
TimeoutException — async polling timed out
