Onymos DocEnhance API is published by [Onymos](https://apis.io/providers/onymos/) on the [APIs.io](https://apis.io/) network.

The published artifact set on APIs.io includes an API reference and authentication docs.

Asynchronous document-image enhancement REST API. POST /api/enhance accepts a base64-encoded image plus a preset (document, auto-crop, photo or watermark) and returns a result_url immediately; GET /api/enhance/results/{UUID} collects the enhanced image as a base64 data URI. Presets remove shadows, wrinkles, speckle noise and non-solid watermarks, auto-crop and deskew, and convert to black and white to raise OCR accuracy and human-in-the-loop verification. Requests are authorised with an onymosIesAuthToken request header. This is the only network API Onymos documents publicly; every other Onymos Feature is consumed as an in-process SDK object.
