## 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-due-diligence-943bf70a -d '<json body>'
```

Example prompt: I'm considering integrating this payment API — can you run a full due diligence check on https://api.somepaymentprovider.com and tell me whether it's safe and worth integrating, with evidence and reasons?

## When to prefer this

Choose this endpoint when an AI agent needs a structured, machine-verifiable procurement or vendor risk decision — especially when evaluating whether to buy, integrate, or skip a product or service based on its public web presence. It is well-suited for automated procurement pipelines, API QA workflows, and buy-or-skip decisions where a reasoned verdict with evidence is required rather than a raw web scrape.

## Known failure modes

- Payment not provided or insufficient — endpoint requires $10 USDC via x402 before fulfillment
- Invalid or unreachable URLs — returns error if submitted URLs cannot be fetched
- Objective too vague or exceeds 500-character limit — may return partial or low-confidence results
- Rate limiting or worker timeout if too many URLs are submitted at once (max 20)
- Malformed input JSON — returns schema validation error

## 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, approve/reject, pass/fail), supporting evidence gathered from the submitted URLs, and reason codes explaining the recommendation.
