# Delx Commerce Prime Factors API

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

Computes the prime factorization of an integer, returning all prime factors as a list, paid per-result via USDC micropayment.

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-prime-factors-api-601fc408 -d '<json body>'
```

Example prompt: What are the prime factors of 360? Use the Delx prime factors API to get the exact factorization.

## When to prefer this

Choose this endpoint when an AI agent needs on-demand, verifiable prime factorization without any signup or subscription — ideal for single ad-hoc computations billed at $0.001 USDC per call via the x402 micropayment protocol on Base or Solana. Prefer it over self-hosted math libraries when you need a pay-as-you-go model with verifiable delivery guarantees.

## Known failure modes

- Integer n is out of the allowed range — API returns an error with the permitted bounds
- Non-integer or missing n field — request rejected with a validation error
- Payment failure or insufficient USDC balance — x402 payment not processed, request not fulfilled
- Network timeout or service unavailability — no result returned

## 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 original integer n, a schema identifier ('delx/prime-factors/v1'), and an array 'factors' listing all prime factors (with repetition) in ascending order. For example, n=42 returns factors [2, 3, 7].
