# Delx LTV CAC Ratio Calculator

> Delx LTV CAC Ratio Calculator is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).

Calculates the LTV-to-CAC ratio and returns a bounded health heuristic as deterministic machine-readable JSON

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-ltv-cac-ratio-calculator-2d97263d -d '<json body>'
```

Example prompt: Can you calculate the LTV-to-CAC ratio and give me a health score for a business where LTV is $450 and CAC is $120?

## When to prefer this

Use this endpoint when you need a fast, stateless, deterministic computation of LTV-to-CAC ratio with a bounded health heuristic score as part of an agent workflow — especially as a preflight check before commercial, policy, or resource allocation decisions. Prefer it over building custom ratio logic when you need a standardized advisory score with no side effects, no data retention, and predictable JSON output for $0.003 per call.

## Known failure modes

- Missing or zero CAC value causing division-by-zero or invalid ratio
- Non-numeric input for LTV or CAC fields
- Negative values for LTV or CAC producing nonsensical ratios
- Payment failure via x402 protocol blocking execution
- Malformed request body missing required fields

## How this service works

Calculate LTV-to-CAC ratio with a bounded health heuristic. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorization and production…

## Output

Returns a deterministic JSON object containing the computed LTV-to-CAC ratio and a bounded health heuristic score, suitable for machine consumption in agent workflows as an advisory preflight or analysis step.
