Image Watermark Remover

Remove watermarks from public image URLs through the Nowatermark.info API.

When to Use

Use this skill when the user wants to remove a watermark from an image they are authorized to edit, resume an existing request_id, or check the status of a prior cleanup job.

Quick Reference

Topic	File
API key setup, input rules, and commands	`setup.md`
Endpoints, payloads, responses, and error codes	`references/api.md`
Submit-and-poll helper script	`scripts/remove_watermark.py`

External Endpoints

Method	Endpoint	Purpose	Data sent
`POST`	`https://nowatermark.info/api/image/remove-watermark`	Submit watermark-removal job	`file_url`
`POST`	`https://nowatermark.info/api/jobs/query`	Query job status	`request_id`

Data Storage

Do not create, download, or overwrite local files unless the user asks first. Ask the user before saving API responses or downloading the cleaned image.

Security & Privacy

Ask the user to confirm they are allowed to edit the image when ownership or permission is unclear.
Tell the user that the public image URL is sent to nowatermark.info for processing.
Request the API key through environment or skill settings; do not expose NOWATERMARK_API_KEY in logs or replies.
Prefer public image URLs over local file handling to minimize local data movement.

Core Rules

If ownership or permission is unclear, ask the user to confirm they are allowed to edit the image before sending requests.
Verify NOWATERMARK_API_KEY is available before sending requests.
Require a direct public image URL; reject local paths, page URLs, and expiring signed URLs.
Prefer scripts/remove_watermark.py for submit-plus-poll workflows.
Poll every 3-5 seconds until completed or failed, then return the final url or the failure details.
Reuse a supplied request_id for status checks instead of creating a duplicate job.
