“Doesn’t list” means the catalog has no record of it for that tool, not that the tool cannot do it.
Verdict
From CoinSeek’s reviewed take on each tool. Neither is declared the winner.
Etherscan
Etherscan is a block explorer for the Ethereum network. It lets people look up transactions, wallet addresses, tokens and smart contracts, and it also offers an API for pulling that data into other software. Beyond basic lookups, the catalog lists a gas tracker, a token approvals page for reviewing permissions given to contracts, contract verification, and a tool for comparing contract code. Data can be exported, and a free tier is available alongside paid options. It covers Ethereum only. One caution from the listing: private transaction notes are not a safe place for passwords or private keys. It suits developers and anyone who wants to check on-chain activity directly.
Best for: Looking up Ethereum transactions; Reviewing token approvals; Checking smart contract code; Developers needing blockchain data
Zerion API
Zerion API is a REST interface for reading onchain wallet data, covering token holdings, DeFi positions, NFTs, transaction history, profit and loss, prices, and swaps. It works across EVM chains and Solana and returns data in a consistent format, with transactions decoded into readable actions. Webhooks let an app receive wallet activity alerts without repeatedly polling, and a CLI and MCP server connect the data to AI tools and agents. A free API key can be created from the Dashboard. It mainly suits developers building portfolio trackers, wallet analytics, or AI-driven apps.
Best for: Developers building portfolio trackers; Wallet profit and loss analysis; Wallet activity alerts via webhooks; Connecting onchain data to AI agents
