Get paid for every call, not every signup
Your API already does the work. This turns each call into revenue without a billing team, a paywall, or a subscription funnel.
No code changes
The gateway wraps your existing API and injects your auth. You do not rewrite anything or add a payment library to get paid.
Paid per call, in USDC
Every call settles on-chain in USDC to your payout wallet. No invoices, no net-30, no waiting on a payment processor to release funds.
You keep the rest
A percentage platform fee applies per settled call and you keep the rest. No monthly fee, no setup cost, and no chargebacks.
You set the price
Put a USDC price on each endpoint and change it whenever you want. Charge a fraction of a cent or more, per call.
Discovered by agents
Publish to the marketplace and AI agents find your service and pay for it on their own. No sales calls, no onboarding forms.
Built on a standard
Payments use x402, the open HTTP 402 standard, settled gaslessly on XDC. Buyers never touch your keys and you never touch a card number.
From existing API to paid endpoint
Most sellers are live in a few minutes. You never deploy a contract or touch the chain.

Connect your API
Point the gateway at your API base URL and add your upstream auth (bearer, API key, or basic). Your secret is encrypted and never leaves the platform.
- 2
Add paid endpoints
Choose which routes to charge for and set a USDC price on each one. Free routes stay free.
- 3
Publish to the marketplace
Make your service public so agents and apps can discover it, read your prices, and start calling.

Get paid
Each paid call settles in USDC to your payout wallet as it happens. Withdraw whenever you want, gasless.
Prefer to keep payments on your own server? Host the API yourself and settle from your backend with the public x402 facilitator.
Turn your followers into cash
Share your invite link with your audience. When the people you refer pay for services on XDC AI, you earn a share of the platform fee, paid as they spend. No repost quotas, no ad reads, no waiting on a brand deal.
- Earn on real usage, not just signups
- One link works across every post and bio
- Your cut comes out of our fee, never your audience's pocket
A share of the platform fee when your audience spends. Illustrative example.
List your API and let agents pay per call
Connect your API, set a price, and publish it to the marketplace. Payments settle in USDC on XDC, straight to your payout wallet.
Questions creators ask
Do I have to change my API to sell it here?
No. The gateway sits in front of your existing API and injects your upstream auth for you, so you do not rewrite anything or add a payment library. It answers the payment challenge, verifies the payment, forwards the call to you, and only settles when your API returns a success. There is no blockchain code on your side.
How and when do I get paid?
Per call. Each paid request settles on-chain in USDC to your payout wallet as it happens, not batched into a monthly payout. There are no invoices, no net-30 terms, and no processor holding your money. You can withdraw whenever you want, and withdrawals are gasless.
What does it cost me to list?
Nothing to list. A percentage platform fee is taken per settled call and you keep the rest, so you only ever pay when you actually earn. There is no monthly fee, no setup cost, and no chargebacks that can claw a sale back after you have delivered it.
Who buys from me?
AI agents and apps that discover your service in the marketplace and pay for it on their own. Because the payment uses the x402 standard, an autonomous agent can pay per call without a human in the loop, so you are not limited to buyers who sign up and enter a card.
Do I need crypto experience to sell?
No. You point the gateway at your API and set a price. Payments arrive as USDC in your payout wallet and you can withdraw them. You never write a smart contract, manage gas, or handle a private key to get paid.
What if I want to run payments on my own server?
You can. Keep hosting the API yourself and call the public x402 facilitator to verify and settle payments from your own backend. The gateway is the no-code path; the facilitator is the self-hosted one. Both settle in USDC on XDC.
