AI Upscale API Documentation

Overview

Enhance the resolution of images and videos using AI super-resolution. Sharpens fine detail and reduces compression artifacts without visible upscale noise.

Primary Endpoint

POST/api/v1/userUpscale/start

Create an asynchronous media-upscaling task for the submitted image or video source and return the record used to monitor processing. ### Request - Send a valid bearer token. The server evaluates the operation in the authenticated caller's access context. - Send an `application/json` body. Required fields: `source_url`. - API-token callers may include `webhook_url` and `webhook_token` for best-effort terminal-state notifications; ordinary JWT/cookie calls ignore these fields. ### Behavior - This is an asynchronous operation: a successful submission creates a task and returns before processing finishes. - Persist the returned task identifier and use the corresponding detail or list operation to observe progress. - Treat the detail endpoint as the source of truth even when webhook delivery is enabled. ### Response - A `200` response confirms task acceptance; it does not by itself mean media generation has completed. - Retain the returned identifier and wait for a documented terminal status before using output URLs. - JSON object responses, including error responses, normally carry a top-level `trace_id` string for this request; include it when contacting support. It is not a task identifier. - Do not infer undocumented fields or statuses; clients should tolerate additional response properties. ### Errors - Non-success responses use the published error envelope; surface the returned message and code to diagnostics. ### Related Operations - `GET /api/v1/userUpscale/allRecords` — Get all task records. - `GET /api/v1/userUpscale/{_id}` — Get task details. - `DELETE /api/v1/userUpscale/{_id}` — Delete task. Authentication: set header Authorization: Bearer <token> (supports user JWT or sk_ API token).

Request Parameters

Name	Type	Required	Description
name	string	No	Name of the upscale task
source_url	string	Yes	URL of the source image or video
model_version	enum: v1 \| v2	No	Upscale model. V2 uses BytePlus AI MediaKit, supports video only, and requires a paid user.; default: "v1"
mediakit_tool_version	enum: standard \| professional	No	default: "standard"
mediakit_resolution	enum: 1080p \| 2k	No	default: "1080p"
mediakit_bit_depth	enum: 8 \| 10 \| 12 \| 16	No	Professional version only.
minor_suspected_skip	boolean	No	Set to true when retrying after error code 1004 to confirm and bypass the suspected-minor soft block.; default: false
webhook_url	string	No	HTTPS URL to receive task.completed / task.failed notifications. Best-effort delivery, single attempt, no retries; clients should treat the detail API as the source of truth.; maxLength: 2048
webhook_token	string	No	Optional plaintext token returned in the X-A2e-Webhook-Token header so receivers can verify the request originated from a2e.; maxLength: 256
