## 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 roster-job-offer-comparison-ac418d90 -d '<json body>'
```

Example prompt: I have two job offers — one from a fintech startup paying $140k with equity and one from a big tech company paying $160k with no equity — can you compare them and tell me which one looks better overall?

## When to prefer this

Use Roster when you need a quick, pay-per-request job offer comparison without setting up subscriptions or API keys. It's ideal for agents that occasionally need to evaluate competing employment packages on behalf of users, especially when USDC micropayment infrastructure is already in place via x402.

## Known failure modes

- Missing offer_a or offer_b fields returns a validation error
- Malformed or empty offer objects may result in incomplete analysis
- Ambiguous or missing compensation fields could reduce comparison accuracy
- Payment failure via x402 (insufficient USDC) returns 402 Payment Required

## How this service works

## Output

Returns a structured JSON object with a success flag and a data object containing the comparison results between offer_a and offer_b, likely including relative rankings, compensation analysis, and a recommended choice.
