I will integrate x402 stablecoin payments into your ai agent API or mcp server
stein blorena
About this gig
If your API creates value on every request, a monthly subscription may be the wrong payment model.
I will integrate x402 stablecoin payments into your AI agent, API, SaaS product, or MCP server. Agents can pay for approved endpoints with USDC and receive verified access without a traditional checkout.
Depending on your package, you can receive:
- x402 payment gating for selected endpoints
- USDC payments on Base
- Server-side payment verification
- Pay-per-request pricing rules
- Wallet authentication and failure handling
- Usage tracking, logs, and admin controls
- Testnet deployment, source code, and documentation
The scope covers technical integration only. You remain responsible for pricing, provider eligibility, wallet control, regulatory requirements, and production funding. I never request seed phrases or private keys.
Send your API documentation, stack, endpoint list, pricing logic, expected users, and deployment environment. I will review compatibility and recommend the right package. Message me before ordering so we can design a payment flow your team can maintain.

FAQ
What is x402?
It enables an API to request payment before releasing a protected resource, allowing pay-per-request access.
Can you integrate an existing API or MCP server?
Yes. I can review the current endpoints, authentication, backend and deployment environment.
Which payment asset is included?
Base USDC is the default scope. Other supported networks require a custom review and quotation.
Can AI agents use the payment flow?
Yes. The integration can allow approved agents to pay for selected endpoints under defined controls.
Do you need access to my private key?
No. Never provide seed phrases or unrestricted private keys. Test and production credentials must be handled securely.
