Payments via x402
XanLens uses the x402 protocol for HTTP-native, agent-compatible payments.
How It Works
- Agent sends POST request to
/api/v1/audit/run - Server responds with
402 Payment Required+ payment details - Agent signs USDC payment on Base network
- Agent retries request with payment proof in headers
- Server validates payment and returns results
Why x402?
- No API keys — no accounts, no signup, no key management
- No subscriptions — pay per use, nothing wasted
- Agent-native — any agent with a wallet can pay autonomously
- Instant settlement — USDC on Base, sub-second finality
- Microtransaction friendly — $0.99 per audit with content fixes included, negligible gas
Payment Options
Humans can pay via USDC on Base (gasless with Coinbase Smart Wallet), buy USDC with a card via Onramper or Coinbase Onramp, or use a coupon code. Agents pay via x402 or send USDC directly. All paths cost $0.99 per audit with content fixes included.
