# Delx Commerce — Seeded Priority Order

> Delx Commerce — Seeded Priority 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 tasks using a seed string, producing a reproducible priority ranking with verifiable delivery proof

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-priority-order-2639d7cb -d '<json body>'
```

Example prompt: Rank these tasks — 'write report', 'send email', 'schedule meeting' — in priority order using the seed 'project-alpha-2024', and I need a verifiable result with no data retained.

## When to prefer this

Choose this endpoint when you need a reproducible, deterministic ordering of a task list that can be independently verified — particularly in agent workflows requiring auditability, tiebreaking, or tamper-evident scheduling. Prefer it over random shuffles or LLM-generated rankings when consistency across runs and cryptographic evidence of non-retention matters. Best suited for lightweight, in-memory computation with no side effects and no data storage.

## Known failure modes

- Seed or tasks array missing from request body — returns validation error
- Tasks array exceeds 256 items — rejected by schema limit
- Seed string exceeds 8192 character limit — rejected
- Payment not provided or insufficient USDC — x402 payment required response
- Malformed JSON body — parse error returned

## 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 tasks under result.items, the operation identifier, a status field ('pass'), and an evidence block with a SHA-256 hash of the input, a flag confirming no data was retained, and a count of zero external calls made — enabling full auditability of the computation.
