How this service works
Validate an EVM, Solana, or Bitcoin address locally (EIP-55 checksum, base58, bech32). Optional eth_getCode on Base to label eoa vs contract. No RPC required by default.
Output
Returns whether the address is valid, the detected or specified chain, the canonical/checksummed form of the address, the address format used (e.g. EIP-55, base58, bech32), and optionally whether it is an EOA or contract (when check_code is true and chain is EVM).
Example use cases
Pre-send wallet address sanity check
“Before I transfer funds, can you validate that '1A1zP1eP5QGefi2DMPTfTL5SLmv7Divf Na' is a valid Bitcoin address so I don't lose anything?”
Smart contract vs EOA detection
“Is '0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48' a smart contract or a regular wallet address on Base? Use on-chain lookup to confirm.”
Auto-detect chain and validate address
“I have this address — 'Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB' — can you figure out what blockchain it's for and tell me if it's valid?”
Technical details
Endpoint
POSThttps://grokzilla.shop/api/skills/address-validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, low-cost address validation without setting up your own RPC node or blockchain library. It handles multi-chain auto-detection (EVM, Solana, Bitcoin) in a single call, enforces EIP-55 checksums, and optionally enriches EVM addresses with on-chain EOA/contract classification via Base — all for $0.001 per call with no API key required.
Side effects
- Invalid or malformed address returns valid=false with format error details
- Unsupported address format for the specified chain returns a validation error
- check_code=true requires EVM chain; using it with Solana or Bitcoin returns an error
- Address string exceeds maxLength of 128 characters returns schema validation error
- Network unavailable when check_code=true (eth_getCode on Base) may cause timeout or partial result
- Duplicate request_id with different body may return cached result rather than recomputing
Input

| chain | string | |
| address | string | Address to validate |
| check_code | boolean | When chain is evm, call eth_getCode on Base to set type eoa|contract |
| request_id | string | Optional idempotency key. Echoed back; a credit-pack redemption with the same request_id and body is charged once. |
