# Delx Commerce — Seeded Load Spread

> Delx Commerce — Seeded Load Spread 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 distributes a list of jobs across a list of workers using a seed value for reproducible, verifiable assignment

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-load-spread-44f94b1f -d '<json body>'
```

Example prompt: Distribute these 5 jobs — j1, j2, j3, j4, j5 — across workers w1 and w2 using the seed 'my-fixed-seed-123', and give me the reproducible assignment for each job.

## When to prefer this

Choose this endpoint when you need deterministic, reproducible job-to-worker assignment with verifiable evidence (SHA256 of input, no data retention, zero external calls) and want to pay per result with no signup. Prefer it over stateful scheduling services when auditability and reproducibility across runs matter, or when operating in an agent context that benefits from on-chain micropayment settlement.

## Known failure modes

- Jobs or workers array exceeds 256-item limit — request rejected
- Seed or job/worker strings exceed 8192 character limit — validation error
- Malformed JSON body — 400 error
- Empty jobs or workers array — may return empty assignments or error
- Payment failure via x402 — 402 response requiring USDC payment on Base or Solana

## 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 an assignments array mapping each job to a specific worker, the schema version, a pass/fail status, and an evidence block containing the input SHA256 hash, a flag confirming no data retention, and a count of zero external calls — enabling full verifiability of the computation.
