Why teams choose Sol402

  • x402-native: Standard 402 → pay → retry flow.
  • Solana-fast: Low fees, instant settlement in USDC-SPL.
  • Frictionless: Works with bots, agents, or browsers.

How it works

  1. You add a source: paste a URL or pick an endpoint.
  2. We answer requests with 402 + PaymentRequirements.
  3. After payment, we proxy the origin response 1:1.

Try the flow

# Request a paid endpoint

curl -i https://sol402.app/p/abc123

# → HTTP/1.1 402 Payment Required

# {
#   "x402Version": 1,
#   "accepts": [{
#     "scheme": "exact",
#     "network": "solana",
#     "asset": "<USDC_MINT>",
#     "payTo": "<MERCHANT_ADDRESS>",
#     "maxAmountRequired": "5000", # 0.005 USDC with 6 decimals
#     "maxTimeoutSeconds": 60
#   }]
# }

# After paying, retry with your payment header

curl -H "X-PAYMENT: <base64-payload>" https://sol402.app/p/abc123

# → 200 OK + X-PAYMENT-RESPONSE
