EVM Address Tools

About this capability

Inspect an EVM address, calculate its EIP-55 spelling and compare address bytes. Mixed-case checksum failures are rejected. Computed within Apiary without contacting a blockchain.

API reference

Two GET tools: /inspect?address={0x-prefixed address} returns lowercaseAddress, checksumAddress, inputCase, matchesEip55Encoding, inputChecksumCheck, addressBytes and isZeroAddress; /compare?a={address}&b={address} inspects both and returns sameAddressBytes. Exact 0x plus 40 ASCII hex characters only. Mixed-case input must match EIP-55 or returns 400 without correction. All-lowercase, all-uppercase and digits-only inputs are accepted without enforcing a supplied checksum, even if matchesEip55Encoding is true; inputChecksumCheck explicitly distinguishes this from verified-mixed-case. Both inputs in compare are independently checked. Zero is accepted and flagged, not approved as a transfer destination. Output uses Keccak-256, not standardized SHA3-256. No whitespace trimming, extra URL decoding, ENS names, URIs, 0X prefix, chain prefix, caller chainId, EIP-1191, bodies or extra parameters. Invalid input returns 400 before shared admission. EIP-55 encoding does not identify a chain, account type/existence, owner, balance or transfer safety; same bytes need not represent the same account/state across networks. No RPC, provider request, wallet, signing, write or payment. Native Apiary computation using the existing pinned viem package; its complete MIT notice is linked in results. Standard: https://eips.ethereum.org/EIPS/eip-55; implementation documentation: https://viem.sh/docs/utilities/getAddress. Shared distributed native admission 120/minute, fail closed. Actual Apiary calls appear in Operations; no external provider account, credits, subscription, invoices or billing/quota feed applies. Apiary artwork identifies its own independent utility, not a connected Ethereum provider or endorsement.
