Reads the designator, resolves the delegate and verdicts it: not_delegated / delegated_known (Coinbase's EOA→SmartWallet path) / delegated_unknown (🚨) / smart_contract. The drain surface no other Base tool checks.","url":"https://402.com.tr/api/x402/wallet-delegation","method":"GET","headers":{},"bodySchema":{"type":"object","$schema":"https://json-schema.org/draft/2020-12/schema","required":["input"],"properties":{"input":{"type":"object","required":["type","method"],"properties":{"type":{"type":"string","const":"http"},"method":{"enum":["GET"],"type":"string"},"pathParams":{"type":"object"},"queryParams":{"type":"object","required":["wallet"],"properties":{"wallet":{"type":"string","description":"EOA address"}}}},"additionalProperties":false},"output":{"type":"object","required":["type"],"properties":{"type":{"type":"string"},"example":{"type":"object"}}}}},"responseSchema":null,"example":null,"exampleRequest":null,"tags":["x402"],"displayCostAmount":"0.03","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"probe","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.03/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.03","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.03","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_2MICyo9cewYhCKXRCXuPW","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.03","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Reads the EIP-7702 delegation designator on a Base EOA address and verdicts whether it is not delegated, delegated to a known safe contract (e.g. Coinbase SmartWallet), delegated to an unknown/potentially malicious contract, or is a smart contract.","exampleAgentPrompt":"Before I interact with this wallet 0x1234...abcd, can you check if it has any EIP-7702 delegation set — I want to know if it's delegated to a known safe contract like Coinbase SmartWallet or something suspicious I should be worried about?","exampleUseCases":null,"resultDescription":"Returns a verdict classifying the wallet as one of: not_delegated (no delegate code), delegated_known (e.g. Coinbase EOA→SmartWallet, considered safe), delegated_unknown (🚨 high-risk, unrecognized delegate that could be malicious), or smart_contract.
