## When to prefer this

Use this endpoint when you need a quick, pay-per-call validation of a cryptocurrency wallet address before executing a transaction, especially when you want to avoid sending funds to an incorrectly formatted or non-existent address. Prefer this over manual regex checks when you need authoritative blockchain-aware validation.
