Swift Bot Labs EVM Address Validator
x402
Swift Bot Labs EVM Address Validator is a paid API for AI agents from x402-toolbox.swiftbotlab.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-31).
Validates an Ethereum/EVM address and returns its canonical lowercase, ERC-55 checksummed form, zero-address flag, and whether it already had a valid checksum.

How this service works
62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.
Output
A JSON object with: ok (boolean), tool name, and a result object containing valid (boolean), isZero (boolean), lowercase (all-lowercase address string), checksummed (ERC-55 mixed-case checksum address string), and hadChecksum (boolean indicating if the input already carried a valid checksum).
Example use cases
Pre-send wallet address sanity check
“Before I send that USDC transfer, validate this recipient address for me: 0xdAC17F958D2ee523a2206206994597C13D831ec7 — is it a real valid EVM address and what's the correct checksummed form?”
Smart contract address normalization
“I've got this contract address in all lowercase — 0x7a250d5630b4cf539739df2c5dacb4c659f2488d — can you normalize it to the proper ERC-55 checksum format and confirm it's valid?”
Zero address detection in user input
“A user just submitted the address 0x0000000000000000000000000000000000000000 as their withdrawal destination — is that a valid EVM address and is it flagged as the zero address?”
Technical details
Endpoint
GEThttps://x402-toolbox.swiftbotlab.workers.dev/v1/evm/address?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call, no-signup EVM address validator that also normalizes to ERC-55 checksum format in a single call. Ideal for agents that only occasionally need address validation and don't want to maintain API keys or subscriptions. Prefer over on-chain or web3.js validation when a pure HTTP utility call is simpler in context.
Side effects
- Missing required 'address' query parameter returns an error response
- Non-hex or completely malformed input may return valid:false rather than an error
- Payment failure via x402 protocol blocks the call entirely before address processing
- Network/worker timeout for edge cases
