Delx Commerce EVM Address Zero Check
x402
Delx Commerce EVM Address Zero Check is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Checks whether a given EVM address is the zero address (0x0000000000000000000000000000000000000000) — a common preflight validation before executing on-chain transactions.

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the echoed input address, a boolean `is_zero` flag indicating whether it equals the EVM zero address, a schema identifier, an advisory status, and evidence metadata including whether any data was retained and a SHA256 hash of the input — no external calls are made and no data is stored.
Example use cases
Pre-transaction burn address guard
“I'm about to send 500 USDC to 0x0000000000000000000000000000000000000000 — can you confirm whether that's the zero address before I proceed?”
Smart contract deployment validation
“We're about to deploy a contract and the constructor takes an address argument — can you check if 0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe is the zero address so we catch any misconfiguration early?”
DeFi protocol input sanity check
“Our agent is about to call a DeFi protocol with recipient address 0x0000000000000000000000000000000000000001 — can you run a zero-address check on it so we know it's safe to continue?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/evm-address-zero-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, trustless, pay-per-use preflight check to detect the EVM zero address with no signup or API key required — ideal for agent pipelines needing verifiable, evidence-backed validation with an immutable audit trail (SHA256 input hash) before executing on-chain transactions.
Side effects
- Malformed or non-hex address string may result in validation error
- Address exceeding 8192 character limit will be rejected
- Network or payment failure via x402 protocol will prevent result delivery
- Ambiguous or checksummed vs non-checksummed address differences may need normalization before submission
