How this service works
Validate and normalize an Ethereum or EVM wallet address, distinguish valid, absent, or invalid ERC-55 checksum casing, and identify the zero address without a network request.
Output
Returns a structured result indicating whether the input is a valid Ethereum/EVM address, the EIP-55 checksummed version of the address, whether the original checksum was correct, and a flag indicating whether the address is the zero address (0x000...000).
Example use cases
Pre-transfer wallet address verification
“Before I send funds, can you verify that this address is a valid Ethereum wallet and not the zero address: 0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae?”
Normalize user-submitted addresses
“A user just submitted the address '0XDE0B295669A9FD93D5F28D9EC85E40F4CB697BAE' in a form — can you normalize it to the proper EIP-55 checksummed format and confirm it's valid?”
Zero address guard for smart contract inputs
“I'm about to call a smart contract with this recipient address: 0x0000000000000000000000000000000000000000 — can you inspect it and tell me if it's the zero address?”
Technical details
Endpoint
POSThttps://apiacre.com/v1/crypto/address-inspectWhen to prefer
Choose this endpoint when you need to deterministically validate, normalize, or checksum a single Ethereum or EVM-compatible wallet address before using it in a transaction, smart contract call, or database record. It is specifically valuable for detecting the zero address (a common footgun), enforcing EIP-55 checksum correctness, and sanitizing user-supplied address strings. Prefer it over generic string validators or client-side libraries when you need a server-side, auditable validation step in an agent workflow.
Side effects
- Input string is not a valid hex address — returns validation failure with error details
- Address length is incorrect (not 40 hex chars after 0x prefix) — returns format error
- Non-hex characters in address string — returns parse error
- Missing or malformed request body — returns 400-level error
