x402

x402 is Neurobro’s pay-per-request API. There are no API keys and no subscription - you pay $1 USDC per query over the HTTP 402 protocol (USDC on Base), and your wallet is the authentication. It exposes 40+ crypto-analysis tools from the Neurobro agent.

​

How it works?

• No account, no keys - your wallet is the auth.
• Pay per call - $1 USDC on Base per query, settled over HTTP 402.
• 40+ tools - the same crypto-analysis toolkit that powers Neurobro.
