# Delx Iota

> Delx Iota is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Generates a sequential integer array from 0 to n-1, returning the values list and count.

## Facts

- Endpoint: POST https://api.delx.ai/api/v1/x402/iota
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/delx-iota-df17f062
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Y0k8ukwT70PGO4wW71X6l

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-iota-df17f062 -d '<json body>'
```

Example prompt: Can you generate an index array of 10 integers starting from 0 for me?

## When to prefer this

Use this endpoint when you need a simple, deterministic zero-based integer sequence without any external dependencies, keys, or data retention. Ideal for agent workflows that require index arrays, slot labeling, or grid mapping on-demand with minimal cost ($0.001 USDC). Prefer over custom code generation when operating in constrained agent environments where local computation isn't available.

## Known failure modes

- Missing or invalid n (non-integer or negative value) may result in a 400 error or empty result
- n of 0 returns an empty list with count 0
- Payment failure over x402 protocol blocks the response
- Extremely large n values may time out or be rejected

## How this service works

Generate 0..n-1 integers. Call when you need simple index arrays for agent maps. Returns values list and count for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.

## Output

Returns a JSON object containing a list of sequential integers from 0 to n-1 and the count of values generated (equal to n).
