# Delx Seeded Load Spread

> Delx Seeded Load Spread is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Deterministically assigns a list of jobs to a list of workers using a seed value for reproducible, balanced load distribution.

## Facts

- Endpoint: POST https://api.delx.ai/api/v1/x402/seeded-load-spread
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402

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-seeded-load-spread-8a39879f -d '<json body>'
```

Example prompt: Distribute these 5 jobs — j1, j2, j3, j4, j5 — across workers w1 and w2 using the seed 'my-seed-42', so I get a reproducible assignment each time.

## When to prefer this

Choose this endpoint when you need reproducible, deterministic job-to-worker assignment — especially for retry-safe pipelines, auditable distributions, or any scenario where the same seed must produce the same mapping. Prefer it over random assignment when idempotency and debugging traceability matter. It processes entirely in memory with no data retention, making it safe for sensitive job identifiers.

## Known failure modes

- Missing or empty jobs/workers arrays may result in empty assignments or an error response
- Jobs or workers exceeding maxItems (256) or maxLength (8192) limits will be rejected
- Invalid seed format may cause non-deterministic behavior or an error
- Malformed JSON input returns a 400-level error

## How this service works

Seeded Load Spread: Seeded Load Spread assigns jobs reproducibly across workers with near-even counts from bounded caller-supplied values without an external provider. Call Seeded Load Spread when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Load Spread as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, st…

## Output

Returns a list of job-worker assignment pairs, where each job is assigned to exactly one worker. The response includes the assignment array, a status field ('pass'), evidence metadata (retained: false, input SHA-256 hash, zero external calls), and the schema identifier 'delx/util-seeded-load-spread/v1'.
