## 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-list-deduplication-df3ada17 -d '<json body>'
```

Example prompt: I have a list of Ethereum wallet addresses that probably has duplicates — can you deduplicate them and tell me how many were removed? The addresses are: 0x1111111111111111111111111111111111111111, 0x2222222222222222222222222222222222222222, 0x1111111111111111111111111111111111111111.

## When to prefer this

Use this endpoint when you need a fast, verifiable, privacy-respecting deduplication of EVM wallet addresses without storing input data. The endpoint processes entirely in-memory with no retention, provides a SHA256 hash for audit purposes, and costs only $0.001 USDC per call with no signup required — ideal for agent workflows that need lightweight, pay-per-use address preprocessing before on-chain actions.

## Known failure modes

- Input array exceeds 256 items — request rejected
- Individual address string exceeds 8192 characters — validation error
- Malformed JSON body — parse error
- Payment not included or insufficient USDC — 402 Payment Required

## 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 deduplicated array of EVM addresses, the count of removed duplicates, a status field ('pass'), an operation identifier, and an evidence block containing a SHA256 hash of the input, confirmation that data is not retained, and a count of zero external calls made.
