How this service works
Token safety check on Base (verified, owner, mint authority, etc.)
Output
Returns safety attributes of the given token contract on Base, including whether it is verified, the owner address, mint authority details, and any other flags indicating risk or legitimacy.
Example use cases
Verify token before swapping
“I'm about to swap for this token on Base—can you quickly check if it's verified and whether the owner and mint authority look legitimate? The contract is 0x833589fC8147050fD9a24220F2d2B8c56EE10D2E.”
Detect rug pull risk signals
“Help me scan this Base token for red flags before I buy in. Check the verification status, owner address, and mint authority to see if anything looks like a potential rug pull setup.”
Audit unfamiliar token safety
“I found this token on Base that I'm interested in—can you run a full safety check on 0xd9aAEc860b1888453b32f4e31567992CdBA12627 and tell me if it passes basic legitimacy checks like verification and safe mint authority?”
Technical details
Endpoint
GEThttps://basesafe-x402.baseagentx402.workers.dev/check/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, affordable ($0.01 USDC) on-chain safety assessment of a specific token contract on the Base blockchain — especially before trading, swapping, or interacting with an unfamiliar token. Prefer this over generic blockchain explorers when you need structured safety flags like verification status, mint authority, and owner in a single API response.
Side effects
- Invalid or malformed contract address returns an error
- Contract address not found on Base network
- Non-contract address (e.g. EOA wallet) may return no token data
- Service unavailable or payment not processed via x402 protocol
- Network timeout on Base RPC queries
