Monetize any API in minutes, not months
The x402 protocol lets clients pay for HTTP requests with crypto. TRXN gives you a hosted gateway that handles the entire flow: protocol negotiation, payment verification, settlement, invoicing, and customer tracking. Configure your endpoints in the dashboard, distribute your gateway URL, and get paid.
Your gateway, your rules
Three steps to a paid API
You configure the endpoint. TRXN runs the gateway. Clients and AI agents pay per-request with USDC.
Configure your endpoint
Create a product and price in the TRXN dashboard. Define your endpoint path, origin server URL, accepted networks, and pay-to wallet address.
Share your gateway URL
TRXN generates a gateway URL for your account. Publish it in your API docs, list it for AI agent discovery, or share it directly with customers.
Payments flow automatically
Clients hit your gateway URL. TRXN handles the 402 response, verifies the payment, settles on-chain via Coinbase CDP, PayAI, or a custom facilitator, and proxies the request to your origin server.
x402 on your own vs. the TRXN gateway
You can implement x402 yourself. Or you can configure an endpoint in TRXN and let us run it.

The business layer x402 doesn't include
Payments are just the start
Raw x402 payments are anonymous on-chain transactions. The TRXN gateway turns them into business records you can actually use.
Automatic invoicing
Micropayments are aggregated into daily invoices with line items per customer. No manual reconciliation. Every cent accounted for.
Customer resolution
Wallet addresses are automatically matched to customer records. Anonymous payers become trackable accounts with payment history across all your endpoints.
Sub-second settlement
Payments settle on L2s like Base and Polygon in under a second. Irreversible, no chargebacks, no payment disputes. USDC keeps the value stable.
Zero custody
TRXN never holds or touches funds. Payments settle directly between payer and your wallet. We observe and record. That's it.
Micropayment friendly
Set any price per request. No minimums. Zero protocol fees, only nominal on-chain gas costs. Built for high-volume, low-value transactions.
Tax-ready reporting
Transaction reports with USD values at time of payment. Revenue by product, by endpoint, by customer. Ready for your accountant.
Built for the agentic web
AI agents pay. You get invoices.
AI agents need to buy data, compute, and API access without human intervention. x402 gives them a native payment mechanism: send a request, get a 402, pay with a wallet, access the resource. No signup, no API keys, no human in the loop.
The TRXN gateway turns those agent payments into business records. Every request is tracked, every wallet is resolved to a customer, and every day you get an invoice. One dashboard for all your agent-driven revenue.
MCP server monetization
Wrap your MCP tools with x402 payment gates. Agents pay per-call, you get invoiced automatically.
Per-wallet spending reports
Track how much each agent (wallet) spends across your endpoints, by day, week, or month.
Multi-agent, one invoice
Multiple agents from one organization route through TRXN. You get a single aggregated invoice.
Sandbox testing
Test your agent payment flows against testnet facilitators before going live. No real funds required.
Use cases
Who needs an x402 gateway
Paid APIs
Monetize any endpoint without building billing infrastructure. Your customers and AI agents pay per-request with USDC. TRXN handles the invoicing.
AI tool providers
Sell data, compute, and API access to autonomous agents. x402 is the payment protocol agents already speak. TRXN is the gateway that tracks every transaction.
Content & data marketplaces
Gate datasets, articles, or downloads behind micropayments. Readers pay for what they access. No subscription required, no account creation.
SaaS with usage-based pricing
