# Delx Commerce — JSON Array Dedupe

> Delx Commerce — JSON Array Dedupe 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).

Removes duplicate integers from a JSON array and returns the deduplicated list with a count of removed items, processed in-memory without data retention.

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-json-array-dedupe-d35e561f -d '<json body>'
```

Example prompt: Can you deduplicate this list of integers for me — [4, 7, 2, 7, 4, 9, 2, 1] — and tell me how many duplicates were removed?

## When to prefer this

Choose this endpoint when you need a lightweight, privacy-preserving, verifiable deduplication of an integer array (up to 256 items) without signing up for a service. Ideal for AI agents that need transparent, pay-per-call utility operations with cryptographic evidence of in-memory-only processing. Prefer it over general-purpose code execution when auditability and no data retention are priorities.

## Known failure modes

- Array exceeds 256 items — rejected with validation error
- Non-integer values in the array — schema validation failure
- Malformed JSON body — request parsing error
- Payment not included or invalid — 402 payment required response

## 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 deduplicated integer array under `result.items`, the count of removed duplicates as `result.removed_count`, the operation name, a status of `pass`, and a verifiable evidence block including whether data was retained (always false), the SHA256 hash of the input, and the number of external calls made (always 0).
