BNB Chain + BaseFree trial. No gas. No card.

No credit card · Connect = a live API key · 30-day window from activation
Get your keys in 30 seconds
No password; connect with Google, email, or wallet. No credit card required; trial activates with one signature on the dashboard.
The live key (q402_live_*) handles your production traffic; the sandbox key (q402_test_*) returns mock results. Both issued in one shot.
Call Q402 with Google, Cursor, Cline, or your own service via MCP. Q402's keeper pays the gas. The recipient gets 100% of the amount.
Everything in the trial
Stablecoin transfers — USDC + USDT on BNB Chain (permanent) and Base (permanent). The payer signs once off-chain, Q402's relayer pays gas, the recipient gets the full amount.
Trial credits live for 30 days from activation. Convert to a paid plan inside that window to keep credits flowing without interruption.
You never deposit native gas into a gas tank. Trial relays draw from the platform's gas budget. Sender pays $0, recipient gets 100%.
Live key signs real on-chain TX. Sandbox key (q402_test_*) returns mock results — use it for integration tests without burning real credits.
Trial credits don't roll over — top up at Pricing to keep gasless payments live. Live key auto-expires 30 days after activation if not converted; sandbox key stays active forever.
