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.
Example use cases
SaaS unit economics health check
“We're spending $120 to acquire each customer and our average LTV is $360 — can you tell me if our LTV to CAC ratio is healthy and whether payback is achievable?”
Marketing budget sanity check
“Our latest campaign has a CAC of $200 and our LTV is $500. Is that ratio good enough or should we be worried about our marketing spend?”
Investor pitch prep
“I need to know if our unit economics look solid before my pitch — our CAC is $50 and LTV is $250. Is the ratio healthy and what should I be aware of?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/ltv-cac?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
