Canonical Swift SDK for the Machine Payments Protocol (MPP) — pay for and charge for machine-to-machine API calls over HTTP 402.
mpp-swift is an early-stage Swift project in the AI payments / x402 ecosystem, focused on agentic-payments, http-402, machine-payments-protocol, mpp. It currently has 7 GitHub stars and 1 forks, and sits alongside related tools like routeweiler-python-sdk, pay-kit, mpp-sdk.
The neutral micropayment router for autonomous agents. A single HTTP client that intercepts '402 Payment Required', routes across x402, L402, and MPP, persists credentials as recoverable assets, enforces per-envelope budgets, and emits a structured trace.
