FAQPage Schema
How do I automate x402 payments on Algorand when accessing protected APIs?▼

To automate x402 payments on Algorand, the Skill detects HTTP 402 responses, selects a payment option from accepts[], builds and signs an atomic transaction group, and retries the original request to obtain the protected resources.

What is an HTTP 402 payment required response and how does MCP handle it?▼

An HTTP 402 response indicates a requested resource requires payment. The MCP tooling handles it by mapping CAIP-2 networks to MCP networks, preparing the fee payer and payment transactions, and exchanging the PAYMENT-SIGNATURE to access the resource.

Do I need wallet access and asset opt-in to execute x402 payments on Algorand?▼

Yes, executing x402 payments on Algorand requires wallet access to sign the fee payer and payment transactions. You must also complete asset opt-in when necessary to ensure the atomic payment group processes successfully.

How do I map CAIP-2 networks to MCP networks for blockchain payments?▼

To map CAIP-2 networks to MCP networks for blockchain payments, the Skill automatically selects a valid payment option from the accepts[] array and prepares the corresponding Algorand transactions for the target network.

What are the limitations of using MCP for x402 protected resources on Algorand?▼

Limitations include strict adherence to the PAYMENT-SIGNATURE format including the accepted object, and the necessity of wallet access and asset opt-in. The original request is only retried after a successful payment signature exchange.
