# Delx Commerce EVM Address Zero Check

> 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.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-evm-address-zero-check-eb7187c7 -d '<json body>'
```

Example prompt: Before I send this transaction, can you check whether the address 0xAbCd1234... is the zero address so I don't accidentally burn funds?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
