Let your AI agent pay for APIs and data without handing it your money. In ChatGPT, Claude or Grok, the agent finds paid x402 APIs (with each seller's payout record from x402 Doctor) and asks to pay; you approve and sign each payment in your own wallet: MetaMask or Coinbase Wallet (USDC on Base), Phantom (USDC on Solana) or Xaman (RLUSD on the XRP Ledger). Fizzl checks every payment before you sign and every paid answer for hidden instructions. Fizzl never holds your keys. Free to start.

Check before money moves. Lorg Check tells an AI agent, or you, whether a token is a trap or an address is unsafe to pay, on Base and Ethereum. In live tests on new launches it blocked traps that GoPlus and Honeypot.is missed. Call check_token before buying or swapping into a token: it simulates a real buy and sell-back through the token’s own pool, reads what the creator can still do, who can pull the liquidity, and whether the creator was paid by a wallet behind earlier rugs. Call check_address before sending funds: sanctions, scam labels, EIP-7702 sweepers and address-poisoning look-alikes. Every answer is signed and says proceed, limit_exposure or do_not_proceed, with a one-line summary to show the user. Free key by GitHub sign-in, or connect with an API key.
