Pricing & Tokens
Simple, per-call pricing
With xPay, you set a price for each request to your endpoint. Callers pay per use - no subscriptions, no manual billing. Payment is verified at request time using the x402 standard.
Default: USDC on Solana
USDC is the default token for its stability and ubiquity.
Prices are entered in standard units (e.g.,
0.05USDC per call).Funds settle instantly to your wallet, with near-zero fees.
Other SPL tokens
You can choose any SPL token by providing its mint address.
Keep prices simple and clear so users and agents can reason about cost.
Tips for setting prices
Start low to encourage trial and adoption.
Consider tiered endpoints (cheap “basic” calls, premium “heavy” calls).
Communicate value: include examples and sample responses.
Refunds and failures
x402 payment is verified before forwarding the request.
If your upstream returns an error, callers still paid to pass the paywall. Keep your upstream reliable and communicate SLAs where relevant.
