# Delx Commerce Ratio API

> Delx Commerce Ratio 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 ratio of two integers (a divided by b) and returns the decimal result

## 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-ratio-api-891d1ad1 -d '<json body>'
```

Example prompt: What is the ratio of 3 to 12? Use the Delx ratio API to compute it.

## When to prefer this

Use this endpoint when an agent needs a lightweight, pay-per-use ratio or division computation with no signup, verifiable delivery, and micropayment billing via USDC on Base or Solana. Ideal for agents that need simple arithmetic as a composable primitive without standing up their own math service.

## Known failure modes

- Division by zero if b=0 (likely returns an error or undefined ratio)
- Non-integer inputs rejected by schema validation
- Missing required fields a or b returns a 400-style error
- Payment failure via x402 if USDC balance is insufficient

## 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 inputs (a, b), the computed ratio as a decimal float (a/b), and a schema identifier string (delx/util-ratio/v1).
