# Delx Seeded Range Sequence

> Delx Seeded Range Sequence is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Generates a deterministic sequence of random integers within a specified range using a seed string, returning the same values every time for the same inputs.

## Facts

- Endpoint: POST https://api.delx.ai/api/v1/x402/seeded-range-sequence
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/delx-seeded-range-sequence-b32f50a9
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_IRhjsrln-9EUBzuOtISQp

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-range-sequence-b32f50a9 -d '<json body>'
```

Example prompt: Generate a seeded sequence of 8 random integers between 1 and 100 using the seed 'morning-launch-42' — I need the same numbers every time I use that seed.

## When to prefer this

Choose this endpoint when you need a deterministic, reproducible sequence of random integers — i.e., the same seed must always yield the same output. Prefer it over true random number generation when auditability, reproducibility, or consistent test fixtures are required. It is not suitable for cryptographic randomness or security-sensitive applications.

## Known failure modes

- Seed exceeds 8192 character limit — request rejected
- Count or minimum/maximum values are missing or non-integer — schema validation error
- Minimum greater than maximum — likely returns error or undefined behavior
- Payment failure (x402) — endpoint returns 402 before computation
- Network timeout — no result returned

## How this service works

Seeded Range Sequence: Seeded Range Sequence generates unique reproducible integers from a bounded range from bounded caller-supplied values without an external provider. Call Seeded Range Sequence 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 Range Sequence as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-…

## Output

Returns a JSON object containing a 'values' array of integers within the specified range, an operation name, a status field ('pass'), and an evidence block confirming no data was retained, no external calls were made, and an SHA-256 hash of the input for auditability.
