Endpoint
POSThttps://mesh.heurist.xyz/x402/agents/EtherscanAgent/get_transaction_detailsWhen to prefer
Use this endpoint when you need to understand the detailed semantics of a specific on-chain transaction — not just raw data but decoded actions like DEX trades or DeFi interactions. Prefer this over generic block explorers when you need structured, machine-readable output about what a transaction actually did, especially for EVM-compatible chains.
