## 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-bankroll-fraction-stake-calculator-a802ded1 -d '<json body>'
```

Example prompt: I have a bankroll of 2000 and want to bet 5% of it — what's my stake?

## When to prefer this

Use this endpoint when an AI agent needs a quick, verifiable, pay-per-use computation of a fractional stake from a bankroll without needing to implement the arithmetic itself — especially useful in agentic betting, trading, or risk management workflows where auditability and deterministic results matter.

## Known failure modes

- Missing required fields (bankroll or fraction) returns an error
- Non-integer bankroll value may cause a validation error
- Fraction outside expected range (e.g. >1 or negative) may yield unexpected results
- 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

Returns a JSON object containing the computed stake amount (bankroll × fraction), along with the original bankroll and fraction inputs echoed back, and a schema identifier string (e.g. delx/util-bankroll-fraction-stake/v1).
