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., 0.05 USDC 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.
