What is PayTrigo Payment Integration?
The PayTrigo skill for Openclaw Skills provides a streamlined interface for AI agents to manage cryptocurrency payments on the Base network using USDC. It is specifically designed for agents that lack webhook infrastructure, utilizing a polling-based status verification system. By leveraging platform API keys, this skill allows for immediate deployment without complex environment variable configuration, making it a cornerstone for commerce-enabled Openclaw Skills.
This integration supports two primary workflows: human-in-the-loop, where the agent provides a payment URL for a user to complete in a browser, and direct bot payments, where the agent signs transactions using a local private key. It prioritizes security and simplicity by handling the complexities of on-chain routing and intent verification within a local environment.
PayTrigo Payment Integration Use Cases
- Enabling AI agents to sell digital goods or services by generating Base/USDC invoices.
- Automating business-to-business payments between autonomous agents without manual intervention.
- Providing a secure payment bridge for human users to fund agent tasks through a browser-based checkout.
- Implementing usage-based billing for AI tools using the robust tracking features of Openclaw Skills.
How PayTrigo Payment Integration Works
- The agent initiates an invoice via the PayTrigo API using a platform key and specifying a recipient address on the Base network.
- For human users, the agent retrieves a payUrl; for direct payments, it fetches a payment intent containing calldata.
- In the bot-pay flow, the agent signs and submits the transaction hash to the PayTrigo router.
- The agent enters a polling loop, checking the invoice status at regular intervals until a final state like confirmed or expired is reached.
- Upon confirmation, the agent triggers the next step in its internal workflow based on the successful transaction.
PayTrigo Payment Integration Setup
Ensure you have Node.js 18+ installed. Install the dependencies and set up your local wallet storage to begin using these Openclaw Skills.
npm install
# Create a new local wallet store
node ./scripts/moltbot-wallet-setup.mjs create --passphrase-file ./passphrase.txt --set-recipient-from-wallet
To import an existing wallet:
node ./scripts/moltbot-wallet-setup.mjs import --pk-file ./payer.pk --passphrase-file ./passphrase.txt --set-recipient-from-wallet
PayTrigo Payment Integration Data Schema & Taxonomy
The skill manages local state and configuration through specific files stored in the .openclawbot directory to ensure persistence across sessions.
| File | Description |
|---|---|
wallet.json |
Encrypted local storage for the bot's private key and wallet metadata. |
wallet-address.txt |
Plaintext reference of the bot's public wallet address. |
recipient.txt |
The destination address for all incoming payments generated by the skill. |
invoiceId / checkoutToken |
Volatile data stored during the session to poll for payment completion. |
PayTrigo Payment Integration Advanced Features
- Idempotency Support: Uses unique UUIDs in headers to prevent duplicate invoice creation during retries.
- Automated Polling Logic: Built-in backoff strategy (3-5s initially, then 10-15s) to stay within API rate limits.
- Intent-Based Payments: Avoids common mistakes by using the PayTrigo Router steps instead of direct token transfers.
- Local Wallet Encryption: Securely stores sensitive private keys using passphrase-protected local JSON files within the Openclaw Skills framework.
