The agentic-letters skill provides a direct interface to physical mail services within Germany. It enables OpenClaw to handle the lifecycle of a physical letter—from creation to the postal system—by automating the interaction with the AgenticLetters API. This skill takes a local PDF file, securely transmits it to a printing service, and ensures it is placed into an envelope and mailed to a specified German address. It is designed for tasks that require formal, paper-based proof of delivery or communication, such as legal notices or formal cancellations.
Installation
To install this skill, run the following command in your terminal: clawhub install openclaw/skills/skills/eisimo/agentic-letters. After installation, you must configure your API credentials. Create the directory ~/.openclaw/secrets and create a file named agentic_letters.env containing your unique API key in the format AGENTIC_LETTERS_API_KEY=al_your_api_key. You can obtain this key by purchasing a credit package at https://agentic-letters.com/buy.
Use Cases
- Formal Cancellations: Quickly send a 'Kündigung' (cancellation) to utility providers, gyms, or insurance companies, ensuring legal compliance.
- Legal Correspondence: Mail formal notices, DSGVO (GDPR) requests, or official documents that require physical documentation.
- Greeting Cards: Automate the mailing of personalized letters or invitations to recipients across Germany.
- Administrative Automation: Keep local track of sent mail through the internal
records/directory, allowing OpenClaw to reference previously sent letters by ID.
Example Prompts
- "OpenClaw, please send the cancellation letter located in my documents folder to my fitness center at Musterstraße 1, 10115 Berlin."
- "I need to mail this PDF as a formal legal notice. Can you handle the delivery for me and check how many credits I have left?"
- "Check the status of my last sent letter and let me know if it has been handed over to the postal service yet."
Tips & Limitations
- PDF Constraints: Ensure your PDF files are A4 sized, not exceeding 3 pages in length, and under 10 MB in size. The service prints in black and white only.
- Regional Scope: Currently, this skill is limited to physical addresses within Germany (country code DE).
- API Keys: There is no separate login system. If you purchase additional credits using the same email, your existing key remains valid; do not attempt to generate new keys unnecessarily.
- Security: Always review your PDF content before triggering the send command to ensure sensitive information is correctly formatted.
