# About the PayAI x402 Facilitator

Who runs this service, what it does with money, and how to get in touch.

## What this service is

This origin runs the PayAI x402 facilitator: the production service that verifies and settles [x402](https://docs.payai.network//x402/introduction) stablecoin payments on behalf of merchants and the agents that pay them. When a server answers a request with HTTP `402 Payment Required`, an x402 client signs a payment, and this service checks that signature and moves the funds on-chain.

It settles on Solana, Base, Polygon, Avalanche, Arbitrum, Sei, X Layer, and SKALE. On Solana it sponsors the transaction fee, so a payer needs only USDC and no SOL.

## Who operates it

PayAI Network, LLC, a Delaware limited liability company. Use is governed by the [terms of service](https://payai.network/terms-of-service); data handling is described in the [privacy policy](https://payai.network/privacy-policy).

General enquiries, support, sales, and security reports: [info@payai.network](mailto:info@payai.network). Legal and privacy: [legal@payai.network](mailto:legal@payai.network). Vulnerability disclosure details are in [security.txt](https://facilitator.payai.network/.well-known/security.txt).

## What it does not do

The facilitator never custodies merchant balances. A settlement moves funds directly from the payer to the address the merchant advertised in its payment requirements; the facilitator signs and broadcasts the transaction and, on Solana, pays the network fee.

It is not a payment processor for consumer checkout. No card payments, no fiat payouts, no bank transfers, no subscription billing.
