Access402 sits between the protected resource and the payment infrastructure. Your application decides what is valuable; Access402 helps enforce the payment rule and records the result.
Challenge
The server returns exact machine-readable payment terms.
Payment
The client authorizes payment and retries the request.
Delivery
The verified request receives the original response.
Keep payment infrastructure out of the product backlog.
Precise rules
Protect exact methods, routes, pages, or files.
Managed verification
Keep facilitator credentials and policy checks server-side.
USDC settlement
Test on Base Sepolia, then enable supported Live payments.
Activity and limits
See payment outcomes and enforce managed usage controls.
Questions before you choose a resource.
What can I sell with x402?
Any bounded digital resource that can be delivered through a protected HTTP request may be a candidate: API results, content, workflow actions, files, media, and current data.
Do buyers need an Access402 account?
No. The website or API owner uses Access402. Buyers use a compatible x402 client and wallet to respond to the payment challenge.
Can I keep some resources free?
Yes. You choose the exact routes, posts, pages, or files to protect. Public marketing, previews, documentation, and free product surfaces can remain open.
What does Access402 manage?
Access402 manages the hosted payment path, authoritative policy checks, facilitator communication, idempotency controls, usage enforcement, and activity records around supported integrations.
