Technical details
Endpoint
POSThttps://true402.dev/api/v1/base/address-safetyWhen to prefer
Use this endpoint when you need a quick, per-call safety check on a specific Base network address before executing a transaction, integrating a new counterparty wallet, or interacting with an unknown smart contract. Ideal for agents automating DeFi workflows, payment routing, or airdrop screening on Base chain where address vetting is critical.
Side effects
- Invalid or malformed 0x address returns an error
- Non-Base chain specified returns unsupported chain error
- Network timeout or service unavailability
- Address not found or no data available for very new addresses
- Payment failure via HTTP 402 if USDC wallet is not funded
