# Delx Commerce Seeded Range Sequence

> Delx Commerce Seeded Range Sequence 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 a reproducible, verifiably seeded sequence of random integers within a specified range, with cryptographic evidence of non-retention and no external calls.

## Facts

- Endpoint: POST https://commerce.delx.ai/api/v1/x402/seeded-range-sequence?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-range-sequence-144efa2e -d '<json body>'
```

Example prompt: Generate a seeded sequence of 8 random integers between 1 and 100 using the seed 'myagent42', and show me the cryptographic evidence that my seed wasn't stored.

## When to prefer this

Choose this endpoint when you need reproducible, verifiable random integer sequences with cryptographic evidence of non-retention and no external dependencies — ideal for agents that must prove fairness, auditability, or determinism. Prefer it over general-purpose random APIs when on-chain micropayment (USDC on Base/Solana) and verifiable delivery are requirements.

## Known failure modes

- Missing or invalid seed string — request fails or returns error
- Count, minimum, or maximum values out of valid integer bounds — computation error returned
- Minimum greater than or equal to maximum — invalid range error
- Payment not completed via x402 — 402 Payment Required response
- Malformed JSON input — 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 integers ('values') within the specified minimum/maximum range, a SHA-256 hash of the input for verifiability, evidence confirming no data was retained and no external calls were made, the operation name, and a schema identifier.
