# Delx Commerce LCM (Least Common Multiple) API

> Delx Commerce LCM (Least Common Multiple) API 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).

Computes the least common multiple (LCM) of two integers, paid per-result via USDC on Base or Solana using x402.

## Facts

- Endpoint: POST https://commerce.delx.ai/api/v1/x402/lcm?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-01
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/delx-commerce-lcm-least-common-multiple-api-65d396f4
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_b55DH-C4LRSm3K-bDkgcz

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-lcm-least-common-multiple-api-65d396f4 -d '<json body>'
```

Example prompt: What is the least common multiple of 18 and 24?

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call, no-signup computation for LCM with verifiable delivery and on-chain micropayment via USDC. Prefer it over building custom arithmetic logic in agent code when you want an auditable, externally-resolved math result, especially in x402-compatible payment pipelines.

## Known failure modes

- Missing or non-integer inputs return a validation error
- Zero as an operand may produce undefined or zero result since LCM(0, n) is mathematically 0
- Payment failure via x402 if USDC balance on Base/Solana is insufficient
- Network or service unavailability returns a 5xx error

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

A JSON object containing the two input integers (a, b), their computed least common multiple (lcm), and a schema identifier string ('delx/lcm/v1').
