Prerequisites

1. Obtain an API key at: https://nanophoto.ai/settings/apikeys
2. Configure NANOPHOTO_API_KEY before using the skill.
3. Do not paste the API key into chat; store it in the platform's secure env setting for this skill.

Preferred OpenClaw setup:

• Open the skill settings for this skill
• Add an environment variable named NANOPHOTO_API_KEY
• Paste the API key as its value

Equivalent config shape:

{
  "skills": {
    "entries": {
      "sora-watermark-remover": {
        "enabled": true,
        "env": {
          "NANOPHOTO_API_KEY": "your_api_key_here"
        }
      }
    }
  }
}

Other valid ways to provide the key:

• Shell: export NANOPHOTO_API_KEY="your_api_key_here"
• Tool-specific env config: any runtime that injects NANOPHOTO_API_KEY

Credential declaration summary:

• Required env var: NANOPHOTO_API_KEY
• Primary credential: NANOPHOTO_API_KEY
• No unrelated credentials are required

If the env var is not set, ask the user to configure it before proceeding.

Workflow

1. Collect the Sora 2 share link from the user (format: https://sora.chatgpt.com/p/...)
2. Validate the link contains sora.chatgpt.com/p/
3. Confirm the user is authorized to process the content and that watermark removal is allowed for their use case
4. Call the API to remove the watermark
5. Return the clean video URL to the user
