# Delx Commerce — IOTA Sequence Generator

> Delx Commerce — IOTA Sequence Generator is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Generates an integer sequence from 0 to n-1 (iota) and returns it as a verifiable array, paid per-call via USDC on Base or Solana using the x402 protocol.

## Facts

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-iota-sequence-generator-b0901ac3 -d '<json body>'
```

Example prompt: Can you generate a sequential integer array of length 5, starting from 0, using the Delx iota utility?

## When to prefer this

Use this endpoint when you need a verifiable, pay-per-call integer sequence utility with no signup overhead and on-chain payment via USDC. Ideal for agent pipelines that need a simple, auditable range/iota array and want to avoid spinning up their own utility logic. Not suitable if you need floating-point ranges, non-zero-based sequences, or large bulk generation.

## Known failure modes

- Missing or invalid 'n' parameter returns a validation error
- Non-integer or negative value for 'n' may result in a 400 error
- Payment failure or insufficient USDC balance via x402 results in a 402 Payment Required response
- Network timeout if the x402 payment flow is not completed in time

## 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 the count of values, a schema identifier ('delx/util-iota/v1'), and a 'values' array of integers from 0 to n-1. For example, n=4 yields {count: 4, schema: 'delx/util-iota/v1', values: [0,1,2,3]}.

## Request schema (JSON Schema)

```json
{
 "type": "object",
 "properties": {
  "n": {
   "type": "integer",
   "description": "Input field: n."
  }
 }
}
```

## Response schema (JSON Schema)

```json
{
 "type": "json",
 "example": {
  "count": 4,
  "schema": "delx/util-iota/v1",
  "values": [
   0,
   1,
   2,
   3
  ]
 }
}
