# Delx Commerce — Seeded Partition

> Delx Commerce — Seeded Partition 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 assigns a list of items to named partitions using a seed string, returning verifiable, reproducible partition assignments.

## 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-partition-c371c837 -d '<json body>'
```

Example prompt: Partition these three jobs — job-a, job-b, and job-c — across two buckets called p0 and p1 using the seed 'sprint-42', and make sure the assignment is deterministic and verifiable.

## When to prefer this

Choose this endpoint when you need deterministic, reproducible assignment of items to named partitions and need a verifiable audit trail confirming no data retention and no external calls. Prefer it over random assignment when repeatability across runs matters, or over custom hashing when you want a managed, pay-per-call primitive without signup overhead. It is ideal for agent orchestration scenarios where task-to-worker routing must be consistent and auditable.

## Known failure modes

- Items or partitions list exceeds 256 entries — request rejected
- Seed string exceeds 8192 characters — validation error
- Malformed request body — 400-class error
- Payment not provided or insufficient USDC — 402 Payment Required
- Network timeout or service unavailability — 5xx error

## 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 a list of assignment objects pairing each item to its assigned partition, the partition names, an operation identifier, a status of 'pass', and an evidence block with the SHA-256 hash of the input, a flag confirming no data retention, and a count of zero external calls.
