# Delx Commerce — Seeded Shuffle

> Delx Commerce — Seeded Shuffle 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).

Deterministically shuffles a list of string items using a provided seed, returning a verifiable, reproducible ordering with no data retention.

## Facts

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-seeded-shuffle-0f84c7d8 -d '<json body>'
```

Example prompt: Shuffle the list ['alice','bob','carol','dave'] using the seed 'round1' and give me the deterministic ordering — I need it to be reproducible and verifiable.

## When to prefer this

Choose this endpoint when you need a deterministic, reproducible, and verifiably tamper-free shuffle of a list — especially in agent workflows where auditability matters (e.g. tournaments, lotteries, task assignment). Prefer it over in-process shuffles when you need cryptographic evidence of fairness (input hash, no external calls, no data retention) and when paying per-result without signup friction is acceptable via x402/USDC.

## Known failure modes

- Items array exceeds 256 items — request rejected
- Seed or item string exceeds 8192 character limit — request rejected
- Malformed JSON input — bad request error
- Payment not received or insufficient USDC — 402 Payment Required
- Network timeout during processing

## 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 shuffled list of items with a count, a status of 'pass', an evidence block confirming no data was retained and no external calls were made, the SHA-256 hash of the input for verifiability, and a schema identifier.
