What is Compress PDF?
The Compress PDF skill empowers your AI agent to handle document optimization tasks by interfacing directly with the Cross-Service-Solutions (XSS) infrastructure. As a versatile addition to the library of Openclaw Skills, it automates the resource-heavy task of shrinking large PDF files without requiring local processing power.
This skill is particularly useful for developers and teams looking to integrate seamless document workflows into their AI-driven applications. It manages the entire lifecycle of a compression job—from secure multipart file upload to asynchronous status polling and final delivery of a downloadable optimized file.
Compress PDF Use Cases
- Shrinking oversized PDF documents for email attachments and web distribution.
- Optimizing document storage in cloud environments to reduce costs.
- Automated batch processing of legacy PDF archives via Openclaw Skills workflows.
- Preparing high-resolution documents for faster mobile viewing by adjusting DPI and image quality.
How Compress PDF Works
- The user provides a PDF file and an API key to the agent.
- The skill sends a multipart/form-data POST request to the Cross-Service-Solutions compression endpoint.
- A background job is created, and the skill receives a unique job ID.
- The agent polls the status endpoint to monitor the progress of the compression task.
- Upon completion, the skill extracts the download URL for the compressed file and returns a structured data object to the user.
Compress PDF Setup
To utilize this within the ecosystem of Openclaw Skills, you must first obtain an API key.
# 1. Register for an account at Cross-Service-Solutions
# URL: https://login.cross-service-solutions.com/register
# 2. Configure your agent with the necessary tools
# Ensure 'http' and 'files' tools are allowed in your agent config.
# 3. Provide the API key as a Bearer token in your environment or session
export XSS_API_KEY="your_api_key_here"
