# Delx Seeded Random Float

> Delx Seeded Random Float 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 one or more deterministic pseudo-random floats within a specified range from a given seed string.

## Facts

- Endpoint: POST https://api.delx.ai/api/v1/x402/seeded-random-float
- 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-random-float-67dcf46a
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_W53tutDvurdNgUlT4ejkJ

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-random-float-67dcf46a -d '<json body>'
```

Example prompt: Generate 5 seeded random floats between 0.0 and 1.0 using the seed 'myproject42'.

## When to prefer this

Choose this endpoint when you need deterministic, reproducible pseudo-random floats — i.e., the same seed must always produce the same sequence. Prefer it over true random endpoints when you need replay-ability, auditability, or consistent test fixtures. It is ideal for agent workflows where randomness must be traceable and verifiable, and where you need to confirm no external state was modified (evidenced by the `retained:false` and `external_calls:0` fields in the response).

## Known failure modes

- Invalid or missing seed parameter returns an error
- Count value of zero or negative integer may return an empty array or error
- Minimum value greater than maximum value may result in a validation error
- Excessively long seed string beyond 8192 characters will be rejected
- Non-numeric minimum or maximum values will cause a schema validation failure

## How this service works

Seeded Random Float: Seeded Random Float returns reproducible floats inside caller bounds from bounded caller-supplied values without an external provider. Call Seeded Random Float 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 Random Float as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, m…

## Output

Returns a JSON object containing an array of pseudo-random float values deterministically derived from the provided seed, along with the minimum and maximum bounds used, a status indicator, and an evidence block confirming no external calls were made and no input was retained.
