550W AI Media Tools for Dify

This Dify tool plugin connects to the 550W Open API for video subtitle removal and short-video watermark removal. It is an adapter for the global Skill; it does not replace the standalone Skill or its CLI.

Configure

Get your user number and API key from the global API page, then enter both in the Dify tool provider settings. The API key is a secret field. Users of the China platform can obtain the same credentials from the China API key page.

Tools

• Check credits reads the shared account balance without creating a task.
• Remove short-video watermark takes a public share link copied inside TikTok or another supported app. A successful result costs one credit. Platform coverage depends on the service response.
• Submit subtitle-removal task takes a direct MP4/MOV URL and the video's actual width, height, and duration. It submits a billable full-frame task. Use a stable idempotency key for retries; without one, a repeat may create another billable task.
• Check subtitle task reads a submitted task's status and result.

The service supports more operations through the standalone Skill, including local media upload and image watermark removal. This Dify package intentionally exposes only the four operations listed above. Do not feed a social share page to the subtitle-task tool; use a direct video URL for that operation.

See privacy information and the service terms. Processing costs and limits are described on the API page. Dify workflows should check the returned before using any result URL.
