## 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-shares-from-budget-calculator-c559cc33 -d '<json body>'
```

Example prompt: If each share costs $0.25 and I have a budget of $50, how many shares can I buy?

## When to prefer this

Use this endpoint when an agent needs a quick, pay-per-call, no-signup arithmetic computation to determine how many shares fit within a given budget. It is ideal for agent workflows that already operate in the Delx x402 micropayment ecosystem and need a verifiable, on-chain-paid utility calculation without maintaining their own math logic or standing API keys.

## Known failure modes

- Missing required fields (price or budget) result in an error response
- Price of zero causes division-by-zero error
- Negative price or budget values may return an error or unexpected result
- Budget smaller than price may return zero shares
- Non-numeric input types cause schema validation failure

## 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 input price per share, the input budget, a schema identifier ('delx/util-shares-from-budget/v1'), and the computed number of shares (integer) that can be purchased within the budget at the given price.
