What is Payment Link Reader?
Payment Link Reader is a robust technical utility designed to bridge the gap between static payment links and actionable AI insights. By interfacing directly with the GStable API, this skill allows AI coding agents and assistants to programmatically fetch product names, descriptions, pricing in USD, and supported cryptocurrency tokens across various blockchain networks.
Integrating this into your workflow through Openclaw Skills ensures that your AI agent can verify payment link validity and present clear, structured data to users. It streamlines the commerce experience by providing real-time metadata for any GStable link ID, making it an essential tool for developers building AI-driven financial or e-commerce applications.
Payment Link Reader Use Cases
- AI assistants parsing user-shared payment links to provide immediate context.
- Displaying comprehensive product lists and images extracted directly from payment links.
- Fetching supported blockchain networks and specific token information for checkout flows.
- Validating payment link status and details before initiating a transaction.
How Payment Link Reader Works
- The AI agent identifies a payment link ID (formatted as lnk_xxx) within a conversation or dataset.
- The skill executes a GET request to the GStable API endpoint using the provided link ID.
- The GStable API returns a detailed JSON payload containing product metadata and payment constraints.
- The skill parses this JSON to extract key information like unit price, quantity, and supported chain IDs.
- The agent summarizes or utilizes this structured data to inform the user or trigger subsequent workflow steps.
Payment Link Reader Setup
To install the skill via the Openclaw Skills manager, run the following commands in your terminal:
clawhub install payment-link-reader
cd ~/.openclaw/skills/payment-link-reader
npm install
Ensure you have Node.js installed on your system. You can optionally set the GSTABLE_API_BASE_URL environment variable if you are using a custom API gateway.
Payment Link Reader Data Schema & Taxonomy
The skill returns a structured JSON object organized as follows:
| Object | Field | Description |
|---|---|---|
| Root | linkId |
The unique identifier for the payment link. |
| Products | name, unitPriceUSD |
The name of the item and its cost in US Dollars. |
| Products | attributes |
List of product variants or traits (e.g., Duration). |
| PaymentTokens | symbol, chainName |
Supported assets (e.g., USDC) and their respective networks (e.g., Polygon). |
| PaymentTokens | amountInUSD |
The calculated total amount required in the specific token. |
Payment Link Reader Advanced Features
- Multi-chain support: Automatically identifies and lists different blockchain networks (Polygon, Ethereum, etc.) supported by the link.
- Custom API Overrides: Flexibility to point to different GStable API environments using environment variables.
- Detailed Attribute Parsing: Captures complex product metadata beyond just name and price, including quantities and custom attributes.
- AI-Ready Formatting: Outputs data in a clean JSON format specifically optimized for LLM consumption within Openclaw Skills.
