How Ax402 works
Three hard steps. Then you fulfill — your way.
The loop
- List what you sell SKU, price, fulfillment mode — webhook for goods you ship, or metered access for API credits.
- Buyer hits 402 and pays Quote → order → HTTP 402 with USDC details. They pay on Base. No card forms. No middlemen holding funds.
- We verify. You deliver. On-chain check passes → your webhook gets the paid order, or a metered API key is issued.
Who does what
| Ax402 | You (merchant) |
|---|---|
| Catalog, quotes, USDC payment verification | Decide SKUs and prices |
| Metered API keys and usage (when that mode is used) | Build whatever your API does |
| Signed “order paid” webhook | Inventory, packing, shipping, customer support |
What Ax402 is not
Not a carrier. Not inventory software. Not another dashboard that owns your customers. Optional prepaid adapters are optional — sell without them.
