# Agent Payment Module (APM)

> The AlgoVoi production agentic payment platform: non custodial live rails and Recurr, plus a separate in development custodial mandate runtime.

APM is AlgoVoi's production agentic-payment platform — the live deployment that runs the substrate work AlgoVoi authors in IETF Internet-Drafts and ships as open-source reference implementations on PyPI and npm.

The platform runs in three schemes:

1. **Live rails** — the realtime **x402, MPP, AP2, and A2A** gateways across **7 chain families** (Algorand, VOI, Hedera, Stellar, Base, Solana, Tempo). **Non-custodial, instant on-chain finality; no customer funds held.**
2. **Recurr** — recurring and subscription payments the customer authorises and pays from their own wallet; each cycle settles in **real time** on-chain. Also non-custodial. See [Recurring payments](/concepts/recurring).
3. **Agentic Payment Mandates** — a fiat-funded (PayPal Orders v2) custodial spending-authority rail. It is **in development** and **subject to the EMR 2011 safeguarding and FCA authorisation requirements** set out in [Mandates](/concepts/mandates). It runs as a **separate runtime** from the live rails and Recurr and does not affect them.
