A facilitator is the stateless service that verifies and settles x402 payments on behalf of a resource server. Choosing one means choosing which chains you accept, what fee structure you absorb, and whose uptime your paid endpoints depend on. Every known production or beta facilitator is listed below.
| Facilitator | Operator | Chains | Fee | Status |
|---|---|---|---|---|
| Coinbase Facilitator | Coinbase | Base, Base Sepolia | Free (reference implementation) | Production |
| The reference x402 facilitator maintained by Coinbase. Settles USDC payments on Base mainnet and Base Sepolia. Zero fee; intended as the canonical integration target for new resource servers. | ||||
| Cloudflare x402 (Workers + AI Gateway) | Cloudflare | Base | Bundled with Workers plan | Production |
| Cloudflare Workers and AI Gateway expose native x402 enforcement at the edge. Any API behind Cloudflare can be gated with a payment header without origin-side code. Cloudflare is a founding member of the x402 Foundation. | ||||
| Alchemy AgentPay | Alchemy | Base, Solana, Polygon, Arbitrum | Variable by plan | Beta |
| Router service launched in private beta in April 2026 that abstracts x402, MPP, L402, and other agent-payment protocols behind a single endpoint. Supports USDC on multiple chains plus compute-credit aggregation for agent workloads. | ||||
| Utexo Facilitator | Utexo | Bitcoin Lightning | Low flat fee | Production |
| Bitcoin-native x402 facilitator that uses the Lightning Network for near-instant settlement. Supports USDT alongside other Lightning-compatible assets. | ||||
| x402 Engine | Community | Base, Solana, MegaETH | Included in API pricing | Production |
| Aggregator front-ending 83+ production APIs (including 51 LLMs) behind x402. Supports USDC on Base, USDC on Solana, and USDm on MegaETH in a single payment flow. | ||||
| AgentPay | AgentPay team | Base | 0% on sub-cent tx | Production |
| Lightweight gateway facilitator focused on agent-originated USDC flows on Base. Pairs with x402-axios and similar client libraries for drop-in enforcement. | ||||
| Google Cloud A2A x402 | Google Cloud | Base | Vertex AI pricing | Production |
| A2A x402 extension for Vertex AI Agents and the AP2 (Agent Payments Protocol) reference implementation. Enables Google Cloud-hosted agents to settle x402 payments as part of a managed tool call. | ||||
| SKALE Zero-Gas Facilitator | SKALE Network | SKALE | Zero gas (subsidised) | Production |
| Settles x402 payments on SKALE's zero-gas EVM network. Useful for extreme-volume agent flows where per-tx gas would otherwise dominate the unit economics. | ||||
| Solana x402 Facilitator | Solana ecosystem | Solana | Sub-cent (lamports) | Production |
| Reference facilitator implementation for Solana with native USDC settlement. Backed by Solana Foundation's membership in the x402 Foundation. | ||||
| Polygon x402 | Polygon Labs | Polygon PoS | Low gas | Production |
| Facilitator support on Polygon PoS. Polygon Labs is a founding member of the x402 Foundation. (Polygon zkEVM is being sunset by Polygon Labs in 2026 and is not a recommended target.) | ||||
| World Chain Facilitator | World | World Chain | Low gas | Production |
| Facilitator for World Chain, tying x402 payments into World ID-verified humans and agents. | ||||
| Avalanche x402 | Avalanche ecosystem | Avalanche C-Chain | Low gas | Production |
| Community x402 facilitator on Avalanche C-Chain with native USDC support. | ||||
| Sei x402 | Sei ecosystem | Sei | Sub-cent | Beta |
| Experimental facilitator on Sei targeting sub-second settlement for high-volume agent APIs. | ||||
| XDC Facilitator | XDC Network | XDC | Low gas | Beta |
| Facilitator for XDC Network, oriented toward enterprise and trade-finance agent flows. | ||||
