# Delx Commerce — Seeded Random Float Generator

> Delx Commerce — Seeded Random Float Generator 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).

Generates one or more deterministic pseudo-random floating-point numbers within a specified range using a user-supplied seed, with verifiable evidence of no data retention.

## Facts

- Endpoint: POST https://commerce.delx.ai/api/v1/x402/seeded-random-float?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402

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-random-float-generator-f3fded11 -d '<json body>'
```

Example prompt: Using the seed 'myagent42', generate 3 random floats between 0 and 1 — I need reproducible results with verifiable proof that the values weren't stored.

## When to prefer this

Choose this endpoint when you need deterministic, reproducible pseudo-random floats that can be independently verified — particularly in agent workflows requiring auditability, fairness proofs, or reproducible simulation runs. Its evidence block (input SHA-256, retained:false, external_calls:0) makes it suitable for trustless contexts. Prefer it over standard RNG calls when you need to prove the randomness was generated honestly and without data persistence, or when you want to pay per result without an API subscription.

## Known failure modes

- Seed string exceeds 8192 character limit — request rejected
- Count not provided or non-integer — may produce default or error
- Minimum greater than maximum — undefined or error result
- Payment not completed via x402 — 402 Payment Required response
- Malformed JSON body — 400 Bad Request

## 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 containing an array of pseudo-random float values within the requested range, the min/max bounds used, a SHA-256 hash of the input for auditability, confirmation that no data was retained, a count of external calls made (zero), and an operation label identifying this as a seeded_decision computation.
