FAQPage Schema

How do AI agents pay for API access using USDC on Base and Solana?▼

AI agents pay for API access using USDC on Base and Solana by utilizing the 402 payment protocol with EIP-712 signatures. This Skill provides Python scripts to execute pay-per-request transactions and manage credit-based access flows.

How do I create and monetize an API endpoint with the 402 payment protocol?▼

You create and monetize an API endpoint by running the included create_endpoint.py script with your API URL and desired USDC price. This deploys your endpoint to the marketplace, enabling 402 payment processing for consumer access.

Does this Skill require a specific Python environment or wallet configuration?▼

Yes, this Skill requires Python 3 along with dependencies like requests, eth_account, and solders. You must configure your wallet environment by exporting your WALLET_ADDRESS and PRIVATE_KEY before executing the payment and deployment scripts.

What is the difference between pay-per-request and credit-based endpoint access?▼

Pay-per-request access charges USDC per individual API call via the 402 protocol, while credit-based access allows consumers to top up endpoint credits in advance using scripts like topup_endpoint.py for bulk usage.

How do I discover available API services in the x402 marketplace?▼

You discover available API services in the x402 marketplace by running the discover_marketplace.py script. This lists all active monetized endpoints deployed on the Base and Solana networks for consumer integration.

Can I use EIP-712 signatures to automate USDC micropayments for endpoint deployment?▼

Yes, EIP-712 signatures are used to automate USDC micropayments for endpoint deployment. The Skill leverages this standard within the 402 payment protocol to facilitate secure, machine-readable transactions on the Base network.
