# Delx Seeded Schedule Offset

> Delx Seeded Schedule Offset 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 computes a time offset in seconds from a seed string and a window duration, using a reproducible hash-based calculation with no external calls or data retention.

## 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-seeded-schedule-offset-33f58412 -d '<json body>'
```

Example prompt: Compute a seeded schedule offset for the seed 'agent-42-prod' within a 3600-second window so I know when to stagger its polling start time.

## When to prefer this

Use this endpoint when you need a deterministic, reproducible time offset derived from a string seed — ideal for distributing scheduled tasks across a fleet of agents or workers without randomness, ensuring the same seed always produces the same offset. Prefer it over random jitter when reproducibility across restarts or deployments matters, or when you need audit-friendly offsets with a hash trail.

## Known failure modes

- Missing required 'seed' field returns a validation error
- Missing or non-integer 'window_seconds' returns a schema validation error
- Seed string exceeding 8192 characters is rejected
- Payment failure via x402 protocol prevents execution
- Malformed JSON body returns a parse error

## How this service works

Seeded Schedule Offset: Seeded Schedule Offset selects a reproducible offset inside a scheduling window from bounded caller-supplied values without an external provider. Call Seeded Schedule Offset 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 Schedule Offset as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First…

## Output

Returns a JSON object containing an offset_seconds integer (the computed time offset within the given window), the operation name, a status of 'pass', and an evidence block confirming no data was retained, no external calls were made, and providing a SHA-256 hash of the input for auditability.
