How these are rankedShowHide
Rule. Every listing in x402’s own category (Payment Rail) that carries a Sato Score, ordered by score tier, observed liveness, deploy-spec and reproduced-install evidence, and chain overlap with x402.
This page ranks peers on how open, active and verifiable each one is — the same evidence Sato Hub publishes everywhere else. It is not a quality, safety or performance ranking, it declares no winner, and it cannot tell you which of these fits your codebase. A Sato Score is not an audit: none of these has been security-reviewed by Sato Hub, and a listing with no earned verification is self-reported.
| # | Alternative | Sato Score | Liveness | Chains | Differs on |
|---|---|---|---|---|---|
| 1 | Stripe's merchant-side agent payments: charge agents per call over MPP (cards via SPTs, USDC on Tempo and Solana) or x402 (USDC on Base), settled to your Stripe balance. no deploy spec on record | High | Active · 7d ago | Base, Solana, Multichain | Does not list Ethereum, Bitcoin; partly open source. |
| 2 | Lightning Labs reverse proxy that puts any HTTP or gRPC API behind L402: Lightning invoices plus macaroon credentials, answered with HTTP 402. no deploy spec on record | High | Active · 2d ago | Bitcoin | Does not list Base, Ethereum, Solana. |
| 3 | Agent Payments Protocol (AP2)✓ reviewed Open protocol from Google for secure agent-led payments across traditional and crypto rails, with a crypto-native x402 extension built with Coinbase, Ethereum Foundation, and MetaMask. uv pip install git+https://github.com/google-agentic-commerce/AP2.git@main install as documented by the project — not reproduced | High | Quiet · 4mo ago | Ethereum, Base, Multichain | Does not list Solana, Bitcoin; deploys as Self-hosted. |
| 4 | PayRam MCP✓ probed PayRam's MCP server for self-hosted crypto payments: hosted endpoints and agent payment workflows. yarn install install as documented by the project — not reproduced | High | Active · 2d ago | Multichain, Bitcoin, Ethereum, Base, Polygon, Tron, Solana, BNB Chain | Also on Polygon, Tron, BNB Chain; partly open source; deploys as Hosted API, Self-hosted (Docker/VPS), Local mode. |

| 6 | TypeScript SDK to put a payment plan in front of an agent: credit or time-based plans, x402 access tokens, and A2A and MCP integrations. no deploy spec on record | High | Active · 7d ago | — | Does not list Base, Ethereum, Solana. |
| 7 | Managed AWS service that lets agents pay for APIs, MCP servers and content over x402 and MPP, using Coinbase CDP or Stripe Privy wallets with per-session budgets. no deploy spec on record | Medium | Active · 2d ago | Base, Solana | Does not list Ethereum, Bitcoin, Multichain; partly open source. |
| 8 | Multi-tenant x402 facilitator for Lightning built on Nostr Wallet Connect. Predates the merged lnbtc spec and still advertises bip122. no deploy spec on record | Medium | Quiet · 5mo ago | Bitcoin | Does not list Base, Ethereum, Solana. |
| 9 | An x402 micropayment gateway and transparent proxy that adds pay-per-request paywalls to existing APIs without backend rewrites. git clone https://github.com/kobaru-io/api-paywall-cookbook.git install as documented by the project — not reproduced | Medium | Quiet · 9mo ago | Solana, Base | Does not list Ethereum, Bitcoin, Multichain; partly open source; deploys as Hosted, Self-hosted, MCP server. |
| 10 | Solana-first x402 payment facilitator enabling usage-based, machine-to-machine payments for AI agents. npx -y payai-mcp-server@latest https://mcp.payai.network install as documented by the project — not reproduced | Medium | no signal | Solana, Base, Polygon, Avalanche, Arbitrum | Also on Polygon, Avalanche, Arbitrum; does not list Ethereum, Bitcoin, Multichain; partly open source; deploys as SDK, API. |
“Differs on” is derived from the records — type, chains, openness and deployment — and states a difference, never a preference. ✓ marks an earned state named as what was checked; none of them is a safety claim.

Questions about alternatives to x402
- What are the alternatives to x402?
- Stripe Machine Payments, Aperture (L402 proxy, Lightning Labs), Agent Payments Protocol (AP2), PayRam MCP, BlindPay, Nevermined, Amazon Bedrock AgentCore Payments, Alby x402 Facilitator, Kobaru, PayAI Network are listed in the same category as x402 (Payment Rail), as of 2026-10-28. The order is Sato Score and observed evidence, not a quality judgment.
- Which alternatives to x402 are open source?
- 4 of 10: Aperture (L402 proxy, Lightning Labs), Agent Payments Protocol (AP2), Nevermined, Alby x402 Facilitator. Openness is read from each project's own published license or repository.
- Which alternatives run on the same chains as x402?
- 9: Stripe Machine Payments, Aperture (L402 proxy, Lightning Labs), Agent Payments Protocol (AP2), PayRam MCP, BlindPay, Amazon Bedrock AgentCore Payments, Alby x402 Facilitator, Kobaru, PayAI Network. Chain support is self-declared by each project unless a named check says otherwise on its listing.
- Has Sato Hub verified any of these?
- Sato Hub reproduced the documented install for 1 of them: BlindPay. Reproducing an install means the documented setup was actually run — it is not a security review, and Sato Hub holds no security assessment of any of these.
- How is this list of alternatives built?
- It is a rule over live records, not a hand-written list: every listing in x402's own category that carries a Sato Score, ordered by the same evidence the rest of the site ranks on — Sato Score tier, whether an endpoint answered our probe, whether a deploy spec exists and was reproduced, a sustained observed record, and chain overlap with x402. It is rebuilt from the records, so it changes when they do.
