Detect ERC-20, ERC-721, ERC-1155 and ERC-165 support plus EIP-1967 proxy control slots in one cheap bounded check, shared across agents for as long as the code at the address is unchanged, up to 7 days, and only for a few blocks when the target is an upgradeable proxy. Positive-sum by design: $0.02 when nobody has checked this contract yet, $0.01 once another agent has — and the wallet that computed it first earns a share of every reuse.","url":"https://www.tereno.xyz/api/v1/capabilities/contract.interface/invoke?utm_source=zero.xyz","method":"GET","headers":{},"bodySchema":null,"responseSchema":null,"example":null,"exampleRequest":null,"tags":["x402"],"displayCostAmount":"0.02","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":"down","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.02/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.02","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.02","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_RPKiNukphocHcF-Q04_YG","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.02","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Detects which ERC/EIP standards (ERC-20, ERC-721, ERC-1155, ERC-165, EIP-1967 proxy) a Base blockchain contract implements, with caching shared across agents.","exampleAgentPrompt":"What token standard does the Base contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 implement — is it ERC-20, ERC-721, ERC-1155, or a proxy?","exampleUseCases":null,"resultDescription":"Returns a structured object with boolean or typed flags per interface (ERC-20, ERC-721, ERC-1155, ERC-165, EIP-1967 proxy slots), an array of reason codes explaining the detection, a validUntilBlock indicating cache freshness, and the contract's bytecode size in bytes.
