What is Breeze x402 Payment API?
The breeze-x402-payment-api is a specialized integration within Openclaw Skills that allows developers and AI agents to interact with Breeze, a leading Solana yield aggregator. Unlike traditional APIs, this tool utilizes the x402 payment protocol, which gates HTTP requests behind USDC micropayments, ensuring a pay-per-use model for DeFi interactions.
This skill provides a robust framework for managing decentralized finance positions directly through code or agentic workflows. By utilizing payment-wrapped fetch requests, Openclaw Skills users can automate complex financial operations on Solana while maintaining precise control over transaction signing and payment authorization.
Breeze x402 Payment API Use Cases
- Automated monitoring of DeFi portfolio balances and APY performance.
- Programmatic deposits into yield-bearing strategies using USDC, USDT, or SOL.
- Facilitating automated withdrawals with intelligent WSOL unwrapping logic.
- Building autonomous financial agents that pay for their own API access via x402.
How Breeze x402 Payment API Works
- The skill initializes a connection to the Solana blockchain using a local wallet and an RPC provider.
- Outgoing HTTP requests are intercepted by a payment-wrapped fetch handler.
- When the Breeze API returns an HTTP 402 status, the handler triggers a USDC micropayment on the Solana network.
- Once payment is confirmed, the handler automatically retries the original request with the required payment proof.
- The skill receives either structured data (for balances) or an unsigned transaction string (for deposits/withdrawals).
- The user or agent signs the transaction locally and broadcasts it to the network to complete the DeFi operation.
Breeze x402 Payment API Setup
To deploy this skill within your Openclaw Skills environment, configure your environment variables and install the necessary dependencies:
export WALLET_PRIVATE_KEY='your_base58_encoded_private_key'
