Welcome to TransX402
IDRX micropayment platform using the x402 protocol — accept Indonesian Rupiah stablecoin payments on your website with ease.
Accept IDRX micropayments on any website using the open x402 protocol — register, get an API key, integrate. TransX402 is the facilitator: we verify payments, submit transactions, and pay gas, so you never touch blockchain infrastructure.
Facilitator in the x402 Ecosystem
- Your server returns an HTTP 402 Payment Required with payment requirements
- TransX402 verifies the buyer's signed authorization and settles it on-chain
- You receive IDRX directly in your merchant wallet — no smart contract code required
Where TransX402 Fits
x402 is an open protocol — several facilitators implement it, each for a different token and network.
| Facilitator | Primary token | Focus | TransX402 relationship |
|---|---|---|---|
| Coinbase CDP | USDC, EURC | Global, multi-chain | Same x402 protocol — CDP doesn't support IDRX |
| PayAI | Multi-token | Solana-first, multi-network | Same x402 protocol — no IDR-native stablecoin |
| TransX402 | IDRX | Indonesia / IDR payments | IDR-pegged facilitator on Base; x402-compatible drop-in |
Already using @x402/fetch or Coinbase middleware?
Same protocol — point your client at TransX402's facilitator and use IDRX instead of USDC. See the Quickstart.

Facilitator Endpoints
Hosted facilitator: https://api.transx402.com — one API for both sandbox and production.
| Environment | Secret key (server) | Publishable key (browser / CDN) | Network |
|---|---|---|---|
| Sandbox | ipk_sandbox_... | ipk_pub_sandbox_... | CAMP Testnet (test IDRX) |
| Production | ipk_live_... | ipk_pub_live_... | Base mainnet |
Keep secret keys on your server (Next.js, WordPress PHP). Use publishable keys only for CDN / direct settlement, and register Allowed Origins in the dashboard first.
Same integration code — swap the key family to go live. The key prefix selects which chain config the facilitator uses.
