# Delx Seeded Nonce Decimal

> Delx Seeded Nonce Decimal 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 decimal nonce within a specified integer range using a seed string, returning the same value for the same inputs every time.

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-nonce-decimal-b86ced20 -d '<json body>'
```

Example prompt: Generate a seeded decimal nonce using the seed 'my-agent-run-42' with a minimum of 1 and a maximum of 1000000 — I need the same number every time for that seed.

## When to prefer this

Choose this endpoint when you need a deterministic, reproducible decimal integer from a seed — meaning the same seed and range always produces the same nonce. It is ideal for agent workflows requiring idempotent random selection, consistent bucket assignment, reproducible tie-breaking, or auditability via input hashing. It is NOT cryptographically secure and should not be used for security-sensitive randomness; prefer a true random source for those cases.

## Known failure modes

- Seed string exceeds 8192 character limit — request rejected
- Minimum greater than or equal to maximum — invalid range error
- Missing required fields — validation error returned
- Non-integer minimum or maximum values — schema validation failure
- Network timeout or service unavailability — HTTP 5xx error

## How this service works

Seeded Nonce Decimal: Seeded Nonce Decimal derives a reproducible non-security decimal nonce inside bounds from bounded caller-supplied values without an external provider. Call Seeded Nonce Decimal 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 Nonce Decimal as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-…

## Output

Returns a JSON object containing: a decimal integer nonce within the requested bounds, a flag indicating whether the output is cryptographically secure (always false), the operation name, a SHA-256 hash of the input for auditability, confirmation that no data was retained, and a count of external calls made (always 0).
