InFlow - agentic MPP / x402 payments from your machine.
InFlow MPP SDK: seller-side inflow method built as a native mppx server method — challenges are minted and HMAC-bound locally by mppx, while verify delegates settlement to the InFlow PSP (POST /v1/mpp/redeem).
InFlow MPP SDK core: the inflow Method definition, protocol types, codec, and HTTP client.
InFlow MPP SDK: buyer-side inflow method that drives the InFlow buyer endpoints (prepare → poll → cancel) and returns the server-produced credential, composed with the mppx foundation client.
