Remove Watermark#

Use this skill when the user wants OpenClaw or another claw-style agent runtime to call the Airemovewatermark API directly.

Configuration#

Required:

• API_KEY

Optional:

• API_BASE_URL

Get it by signing up at https://airemovewatermark.net. Newly registered users can process 3 watermark-removal tasks for free.

Example:

bash

export API_KEY="rwm_xxx"

On Windows PowerShell:

powershell

$env:API_KEY = "rwm_xxx"

If API_BASE_URL is not set, the skill uses:

text

https://airemovewatermark.net

Core workflow#

1. Read the target image path or remote image URL from the user.
2. Confirm the user wants to process that image through the remote API.
3. Run remove.
4. If the task is still running, poll it with task --task-id ....
5. If the user wants a local copy, rerun with --download true or use the returned output_url.

Bundled script#

Use the bundled script for all API calls:

• scripts/remove_watermark.mjs

Supported commands:

• credits
• remove --file <path>
• remove --image-url <url>
• task --task-id <id>

Important options:

• --wait true|false
• --download true|false
• --api-key <rwm_xxx>

Execution guidance#

• Prefer remove --file ... for local images.
• Prefer remove --image-url ... for remote images.
• Use task --task-id ... only when a previous remove call returns an unfinished task.
• Treat credits as optional. If it fails because the key is invalid or not authorized, continue only after the user fixes credentials.
• Downloading is opt-in. When --download true is used, completed jobs are saved under .openclaw-artifacts/remove-watermark/.
• Prefer the top-level result_file, output_url, result_summary, and status fields in the script output instead of parsing only the raw API payload.

Example commands#

bash

node scripts/remove_watermark.mjs credits

bash

node scripts/remove_watermark.mjs remove --file /absolute/path/to/image.png

bash

node scripts/remove_watermark.mjs remove --file /absolute/path/to/image.png --wait true --download true

bash

node scripts/remove_watermark.mjs remove --image-url https://example.com/image.png --wait true

bash

node scripts/remove_watermark.mjs task --task-id task_xxx --download true

Expected result shape#

Successful responses return JSON. Pay attention to:

• status
• result_file
• result_summary
• task_id
• raw.data.task.status

Notes#

• The API accepts either Authorization: Bearer <key> or x-api-key
• The script prints structured JSON to stdout for both success and failure
• The skill targets https://airemovewatermark.net
• remove --wait true uses short polling and may still return an unfinished task after about 30 seconds; if that happens, continue with task --task-id ...
• Local files are uploaded to the remote API as part of processing
• If a job finishes successfully and --download true is used, the script downloads the result into .openclaw-artifacts/remove-watermark/ and exposes the local file path through result_file
• Output links are temporary and should be saved promptly
• If the API reports insufficient credits, stop and tell the user clearly
• credits uses the same API key auth path as the main API, so invalid or revoked keys will fail there too
• Only use this skill for images you own or are authorized to edit
