Payments via x402
XanLens uses the x402 protocol for HTTP-native, agent-compatible payments.
How It Works
- Agent sends POST request to
/api/v1/fix - 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 Pro Audit, $0.99 Pro + GEO Skill, negligible gas
Free Website Access
The website UI at xanlens.com provides free access to demonstrate value. The x402 payment flow applies only to API calls, allowing agents and developers to integrate programmatically while humans can test freely.
