## 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 agent-rest-stop-two-quote-minimum-96bded97 -d '<json body>'
```

Example prompt: I have two quotes: 'Vendor Alpha' for $42.50 and 'Vendor Beta' for $38.00 — which one is cheaper?

## When to prefer this

Use this endpoint when you have exactly two labeled price quotes as strings and need a fast, stateless determination of which is smaller, especially in agent pipelines where you want a pay-per-use micro-computation without managing comparison logic yourself.

## Known failure modes

- Missing or non-numeric amount fields cause comparison to fail or return unexpected results
- Both amounts equal — tie-breaking behavior may not be specified
- Malformed string amounts (e.g. currency symbols embedded) may cause parse errors
- Payment of $0.01 USDC required per call; missing payment returns 402 error

## How this service works

Picks the smaller quote.

## Output

Returns the label and amount of whichever of the two input quotes has the smaller numeric value, allowing the caller to immediately act on the cheaper option.
