How this service works
Check a Base token contract address for native Circle USDC vs bridged USDbC status, decimals, and EIP-3009 v2 signing readiness.
Output
Returns the classification of the token as native Circle USDC or bridged USDbC, the token's decimal precision, and whether the contract is ready for EIP-3009 v2 (transferWithAuthorization) signing — key for x402 payment compatibility checks.
Example use cases
Pre-payment token compatibility check
“Before I accept x402 payments, check if the token contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base is native Circle USDC and whether it supports EIP-3009 v2 signing.”
Distinguish native vs bridged stablecoin
“I have a Base token address 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA — is that the real native USDC or is it the bridged USDbC version, and what are its decimals?”
Validate token before DeFi integration
“We're integrating a new Base token at address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 into our payment flow — can you verify its decimals and confirm whether it's native USDC or a bridged variant?”
Technical details
Endpoint
GEThttps://bot-bazaar.fly.dev/v1/x402/token-metadata-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly verify whether a Base token contract address is the canonical native Circle USDC versus the bridged USDbC variant, especially before configuring x402 payment flows or EIP-3009-based authorization signing. It is purpose-built for Base chain stablecoin classification and signing readiness, making it ideal for AI agents orchestrating on-chain payments or DeFi integrations on Base.
Side effects
- Invalid or malformed contract address returns an error
- Non-token or non-ERC20 contract address may return unknown classification
- Network or RPC issues querying Base chain can cause timeouts
- Address not deployed on Base returns no metadata
