# Delx Commerce — Seeded Jitter Ms

> Delx Commerce — Seeded Jitter Ms is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Computes a deterministic, seed-based jitter offset in milliseconds applied to a base delay, returning the final delay and jitter values with verifiable evidence.

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-jitter-ms-331b2101 -d '<json body>'
```

Example prompt: Calculate a seeded jitter for me: use seed 'agent-retry-42', a base delay of 1000ms, and a jitter fraction of 0.2 — I need the final delay and jitter values.

## When to prefer this

Choose this endpoint when you need a deterministic, reproducible jitter value derived from a known seed — especially in distributed or multi-agent systems where multiple agents must independently arrive at the same delay without coordination, or when you need an auditable evidence trail showing inputs were not retained and no external calls were made.

## Known failure modes

- Missing required fields (seed, base_ms, jitter_fraction) result in validation error
- Seed string exceeding 8192 characters may be rejected
- Invalid types (e.g. non-integer base_ms) cause schema validation failure
- Payment failure via x402 prevents call from completing

## 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 the computed delay_ms (base plus jitter) and jitter_ms (the signed offset), plus an evidence block containing a sha256 hash of the input, confirmation that no data was retained, and the count of external calls made (always 0), enabling verifiable and reproducible results.
