How this service works
Verify a token contract is the canonical asset (real USDC, WETH, DAI…) and not a lookalike or spoof. Part of x402 Agentic, the payment-trust suite for AI agents on Base USDC.
Output
Returns a verification result indicating whether the queried contract address matches the canonical, official deployment of a known token (USDC, WETH, DAI, etc.), including whether it is a potential spoof or lookalike.
Example use cases
Verify token before autonomous payment
“I need you to send 500 USDC to that wallet, but first make absolutely sure the token contract address we're using is the real, canonical USDC and not some spoof that'll drain our funds.”
Detect fake tokens in liquidity pools
“Can you scan these three token addresses from that new liquidity pool and tell me which ones are legitimate canonical assets like WETH or DAI versus potential scamware trying to trick traders?”
Validate contract before multi-swap route
“I want to execute a swap chain through several DEXes today—before you route anything, can you quickly verify each token contract address in the path is the real deal and not a lookalike?”
Technical details
Endpoint
GEThttps://api.x402agentic.ai/token-checkWhen to prefer
Use this endpoint before any DeFi transaction, token swap, or payment where you need to confirm you are interacting with the real, canonical version of a well-known token rather than a lookalike or fraudulent contract. Especially important for AI agents autonomously handling payments on Base or other EVM chains.
Side effects
- Invalid or malformed contract address returns an error
- Unknown token addresses may return inconclusive results
- Network unavailability returns a service error
- Address not found in canonical registry returns unverified status
