What is curl-http?
curl-http is a foundational utility within the Openclaw Skills ecosystem designed to streamline web communication directly from the terminal. It provides a robust set of commands for interacting with various protocols, primarily focusing on HTTP and HTTPS. Developers can use this skill to perform everything from simple GET requests to complex multi-part form uploads and authenticated API interactions.
By leveraging this skill, users gain a standardized way to automate web tasks, debug network connectivity, and integrate remote data into their local workflows. Whether you are a backend engineer testing endpoints or a DevOps specialist monitoring service health, this Openclaw Skills entry serves as a comprehensive reference for modern web development and network troubleshooting.
curl-http Use Cases
- Testing RESTful API endpoints using various HTTP methods like GET, POST, PUT, and DELETE.
- Automating the download of large files or assets using resume-capable transfer commands.
- Debugging SSL/TLS handshake issues or inspecting HTTP response headers for security audits.
- Authenticating with web services using Bearer tokens, Basic Auth, or custom API keys in headers.
- Simulating different client environments by modifying User-Agent strings and other custom headers.
How curl-http Works
- The user identifies the target URL and determines the required HTTP method (GET, POST, etc.) for the specific task.
- Necessary authentication credentials or custom headers are prepared and passed as specific command flags.
- The skill executes the curl command, which establishes a secure connection to the remote server using the underlying system binary.
- Data is transmitted to the server, such as JSON payloads or multipart forms, and the server's response is captured.
- The resulting output, headers, or binary files are processed, displayed in the terminal, or saved to the local filesystem for further analysis.
curl-http Setup
To use this skill within the Openclaw Skills framework, ensure that the curl binary is installed on your operating system. Most Unix-like environments (Linux, macOS) and modern Windows versions include it by default.
Verify your installation with the following command:
curl --version
To test a basic GET request and verify connectivity, run:
curl -I https://example.com
curl-http Data Schema & Taxonomy
The curl-http skill processes request parameters and manages response data dynamically. It organizes its interaction metadata and file outputs according to the following structure:
| Data Component | Format | Description |
|---|---|---|
| Request Payload | JSON / Form-Data | Data sent to the server, often defined in files like data.json. |
| Output Files | Binary / Text | Content saved to disk using the -o (output) or -O (remote-name) flags. |
| Cookie Jar | Text File | Session and cookie data stored and read using -c and -b flags. |
| Trace Logs | ASCII Text | Comprehensive diagnostic logs generated via --trace-ascii for debugging. |
| Response Metadata | HTTP Headers | Information including status codes, server types, and cache-control headers. |
curl-http Advanced Features
- Multi-protocol support including HTTP, HTTPS, and FTP for versatile data movement.
- Robust proxy support for HTTP and SOCKS5, allowing for secure requests through corporate firewalls.
- Automatic retry logic with configurable delays and max-time limits to ensure reliability in unstable networks.
- Detailed performance timing to measure DNS lookup, TCP connect, and TLS handshake durations.
- Seamless integration with pipe-based workflows, allowing JSON responses to be parsed instantly by tools like jq.
