Zero Address Detector
x402
Zero Address Detector is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-19).
Detects whether an EVM address is the zero address (0x0000...0000), returning a boolean and normalized address for validation use cases.

How this service works
Detect the zero EVM address used as empty/burn/default sentinel. Call when validating recipients or detecting unset address fields safely. Returns boolean is_zero plus normalized address as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
Returns a deterministic JSON object with a boolean field `is_zero` indicating whether the input is the EVM zero address, plus the normalized form of the input address. No external calls are made; result is computed locally from pure math.
Example use cases
Pre-transfer recipient validation
“Before I send tokens, can you verify that 0xAbCd1234000000000000000000000000DeadBeef is not the zero address so I don't accidentally burn them?”
Smart contract default address check
“I just read an address field from a contract and got 0x0000000000000000000000000000000000000000 — can you confirm if that means the field is unset or zero?”
DeFi pipeline address guard
“My DeFi agent is about to call a swap with recipient 0x0000000000000000000000000000000000000000 — can you check if that's a zero address and flag it before we proceed?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/address-is-zero?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, deterministic, no-RPC check to confirm whether an EVM address is the zero/burn/sentinel address (0x000...000) before using it as a recipient or validating contract state. Ideal for agents that need a cheap ($0.001 USDC), side-effect-free, API-key-free validation step in a larger workflow.
Side effects
- Invalid or malformed address string returns an error response
- Missing address field in request body results in validation error
- Non-hex or improperly checksummed addresses may not parse correctly
