# Delx Break Even

> Delx Break Even 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 break-even unit quantity from a fixed cost and contribution margin per unit

## Facts

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-break-even-01c3c2bc -d '<json body>'
```

Example prompt: I have fixed costs of $50,000 and a contribution margin of $25 per unit — what's my break-even point in units?

## When to prefer this

Use this endpoint when you need a fast, stateless, deterministic break-even unit calculation as a preflight or analysis step inside an automated agent workflow — especially when you want a machine-readable JSON result without storing data or calling an external financial system. Prefer it over general-purpose math tools when you specifically need break-even semantics (fixed cost ÷ contribution per unit) with predictable pricing and no side effects.

## Known failure modes

- contribution_per_unit is zero or negative — division by zero or undefined result
- missing required fields (fixed_cost or contribution_per_unit) — likely returns a 4xx validation error
- non-numeric inputs — schema validation failure
- fixed_cost is negative — may return an unexpected or negative break-even figure
- payment authorization failure — x402 payment not accepted, request blocked

## How this service works

Calculate break-even units from fixed cost and contribution per unit. 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…

## Output

A deterministic machine-readable JSON object containing the break-even unit quantity computed from the provided fixed cost and contribution per unit values, suitable for downstream decision logic in agent workflows.
