# Delx Commerce LTV/CAC Ratio Calculator

> Delx Commerce LTV/CAC Ratio Calculator is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-01).

Computes the LTV-to-CAC ratio from two numeric inputs and returns a health assessment with advisory guidance

## 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-ltv-cac-ratio-calculator-640a97e9 -d '<json body>'
```

Example prompt: My customer acquisition cost is $80 and my customer lifetime value is $300 — is that a healthy LTV to CAC ratio and can I realistically achieve payback?

## When to prefer this

Choose this endpoint when you need a quick, deterministic LTV:CAC ratio computation with a built-in health heuristic and advisory, without setting up a billing account. Ideal for AI agents that need pay-per-call unit economics checks with verifiable USDC micropayments on Base or Solana.

## Known failure modes

- Missing or non-numeric 'ltv' or 'cac' fields return a validation error
- CAC of zero causes division-by-zero error
- Negative values may produce nonsensical ratios without explicit error
- Payment failure via x402 (insufficient USDC balance) results in HTTP 402 and no result

## How this service works

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

## Output

Returns the computed LTV:CAC ratio as a float, a boolean 'healthy' flag indicating whether the ratio meets a standard heuristic threshold, a 'payback_possible' boolean, and an advisory string noting that the threshold is a heuristic and recommending comparison with gross margin and payback period. Also echoes back the input CAC and LTV values along with a schema identifier.
