# Delx Commerce — EVM Multisend Recipient Check

> Delx Commerce — EVM Multisend Recipient 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).

Validates a list of EVM recipient addresses for a multisend transaction, detecting duplicates, unexpected addresses, and zero-address entries against an allowed list.

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-multisend-recipient-check-a4a81b60 -d '<json body>'
```

Example prompt: Before I send USDC to this batch of wallet addresses, can you run a preflight check to make sure there are no duplicates, zero addresses, or unexpected recipients not on my allowed list? Allowed list: [0xAAA...], recipients: [0x111..., 0x222..., 0x333...]

## When to prefer this

Use this endpoint when you need a lightweight, trustless, pay-per-call preflight check on EVM multisend recipient lists before executing a batch transfer — particularly when you need cryptographic evidence (SHA-256 input hash) that no data was retained, and when you need duplicate/unexpected/zero-address detection in a single atomic operation without a signup or subscription.

## Known failure modes

- Malformed or non-EVM address strings cause parsing errors
- Exceeding 256-item limit on allowed or recipients arrays returns a validation error
- Missing required arrays results in a schema error
- Network or payment (x402) failure prevents the call from completing

## 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 with a status (pass/fail), list of validated recipients, arrays of any duplicate or unexpected addresses found, a boolean flag for zero-address presence, and cryptographic evidence including an input SHA-256 hash confirming no data was retained externally.
