To handle HTTP 402 payment responses, you need a unified payment dispatcher that automatically detects the response and routes the transaction to the appropriate payment scheme and intent for processing.

In machine payment protocol (MPP), the charge intent enables one-shot single payments, while the session intent handles multi-request payments, allowing continuous machine payment interactions across multiple requests.

Yes, you can process agent-to-agent payments without an HTTP 402 response by using a2a-pay integration, which directly handles transactions through paymentId-based links between agents.

Yes, processing payments with ERC-20 tokens requires an EVM environment, specifically utilizing the EIP-3009 standard for transfers and local key signing or a TEE for cryptographic operations.

The best way to unify payment processing for digital distribution is implementing a single dispatcher that handles HTTP 402, MPP, and a2a-pay protocols, simplifying transactions across various schemes.

You need local key signing or a Trusted Execution Environment (TEE) to securely perform the cryptographic operations required to authorize and validate payments processed through MPP and a2a-pay protocols.
