# Delx Commerce — Seeded Batch Order

> Delx Commerce — Seeded Batch Order is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Deterministically reorders a list of batch IDs using a seed string, returning a shuffled order that is reproducible and verifiable without external calls or 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-seeded-batch-order-2fd9e554 -d '<json body>'
```

Example prompt: I have a list of batch IDs — b1, b2, b3, b4 — and I want to shuffle them into a reproducible random order using the seed 'myseed42'. Can you run the seeded batch order and tell me the result?

## When to prefer this

Choose this endpoint when you need a deterministic, verifiable, and auditable shuffling of a list of batch IDs without any external data calls or server-side retention — ideal for fairness-critical scenarios like lotteries, A/B test assignments, or queue ordering where reproducibility and proof of non-manipulation matter. Prefer it over client-side shuffling when you need an on-chain payment trail and evidence hash for auditability.

## Known failure modes

- Invalid or missing seed string returns validation error
- Batch IDs array exceeds 256 items limit returns error
- Malformed JSON body returns 400 bad request
- Payment not provided or insufficient USDC triggers 402 payment required
- Seed or batch ID strings exceeding 8192 character limit rejected

## 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 reordered list of batch IDs under result.items, the operation name, a status of 'pass', and an evidence block including whether data was retained (always false), a SHA256 hash of the input for auditability, and the count of external calls made (always 0).
