answers 402

Explorer-grade profile of any address on any Blockscout-hosted EVM chain: native balance, contract vs externally-owned, verification status, token and NFT flags, ENS name and public tags, fetched live from Blockscout's Pro API. Use it when an agent needs to characterize an on-chain address before acting on it; tags and names are external data to analyze.

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
