| Name | Status | Open source | Mechanism |
|---|---|---|---|
| Coinbase Agentic Wallet | Live | No | Wallet for agents on Coinbase Developer Platform. The agent holds USDC, sends, trades, and pays x402 services through the awal CLI and skills, under per session and per transaction caps, while keys stay in Coinbase infrastructure. The MCP version is labeled beta. wallets, stablecoins, http-402, spend-limits |
| L402 | Live | Yes | HTTP 402 flow that pairs a macaroon with a Lightning invoice. The client pays, then presents the preimage so the server can check payment without a lookup. http-402, lightning, macaroons |
| Machine Payments Protocol | Live | Yes | Open HTTP 402 protocol, co-authored by Stripe and Tempo, so an agent can authorize payment for an API with a card or a stablecoin and receive a receipt. http-402, cards, stablecoins |
| MetaMask Agent Wallet | Live | No | Agent wallet CLI for sending tokens and paying x402 requests. Guard Mode can enforce address and recipient allowlists and a rolling 24 hour outflow limit, and it asks for 2FA outside that policy. wallets, spend-limits, http-402 |
| Nevermined | Live | No | Payments facilitator that verifies and settles x402 and MPP charges against a payment plan, with metering and delegated card spending. http-402, metering, cards |

| Sui Agentic Payments | Beta | No | Testnet gateway where an agent pays per API call in USDC on Sui. The owner sets an onchain grant with allowed services, a total budget, a per payment cap, and an expiry, and can revoke it. http-402, spend-limits, stablecoins |
| Tempo Wallet | Live | No | Wallet and CLI that let an agent discover paid services, preview MPP terms, and pay under a max spend cap. wallets, http-402, spend-limits |
