## 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 open-horizon-machine-revenue-preflight-decision-4adb8ec1 -d '<json body>'
```

Example prompt: Can you run a preflight decision on https://acme-supplier.com to check whether we should proceed with procurement — I want a buy-or-skip verdict with evidence and reason codes?

## When to prefer this

Choose this endpoint when an AI agent needs a structured, machine-verifiable pass/fail or buy/skip verdict on a specific URL — particularly for procurement screening, vendor risk scoring, API QA, or consumer purchase decisions — and needs evidence and reason codes rather than raw page content. It is preferable over general web scrapers when the agent needs an opinionated decision output rather than raw extraction.

## Known failure modes

- Missing required `site_url` or `urls` field returns a schema validation error
- Payment not fulfilled via x402 results in 402 Payment Required before any analysis
- Invalid or unreachable URL causes a fetch/resolution failure with no decision returned
- Objective string exceeding 500 characters is rejected
- More than 1 URL in the `urls` array violates maxItems constraint

## How this service works

Agent decision products for procurement, vendor risk, API QA and public-web buy-or-skip workflows. Strict x402 payment is required before fulfillment.

## Output

A structured JSON object containing a machine-verifiable decision (e.g. buy/skip, pass/flag), supporting evidence extracted from the evaluated URL, and human-readable reason codes explaining the verdict. The `machine_verifiable: true` field confirms the result is suitable for automated downstream processing.
