Foresight News reports that the on-chain data platform Nansen API now supports the Machine Payments Protocol (MPP), allowing agents to pay directly through their wallets based on usage. MPP is the standard for autonomous machine-to-machine payments, backed by Tempo and Stripe. This feature runs in parallel with x402 and the Nansen API keys, with endpoints, data, and pricing (starting at $0.01 per call) remaining unchanged.
