## 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 diogo-ai-condition-verification-3c8ad452 -d '<json body>'
```

Example prompt: Check whether this product page at https://example.com/product-123 meets these three conditions: it shows a price below $50, it says 'in stock', and it lists free shipping — give me a clear yes/no decision with the evidence you found.

## When to prefer this

Use this endpoint when you need a structured, evidence-backed yes/no decision about whether a specific public web page satisfies a defined checklist of conditions — rather than a general-purpose summary or analysis. It is particularly useful for compliance checks, price/availability monitoring, fact verification, and any scenario where you need auditable evidence that a page meets stated criteria. Prefer it over generic web scraping when conditions can be expressed as concrete boolean statements.

## Known failure modes

- URL is inaccessible, private, or returns a non-200 status — verification cannot proceed
- Page is JavaScript-rendered and content cannot be retrieved statically
- Conditions are ambiguous or contradictory — may produce uncertain results
- Page content has changed since crawl — evidence may be stale
- Too many conditions supplied (max 10) — request rejected
- Invalid URL format — request rejected with validation error

## How this service works

Verifica se uma página web pública cumpre condições concretas e devolve uma decisão com evidência.

## Output

Returns a structured decision indicating whether the web page satisfies each specified condition, along with evidence (excerpts or observations from the page) supporting the decision for each condition. Includes an overall pass/fail verdict.
