# Website Evidence Pack

> Website Evidence Pack is a paid API for AI agents from website-evidence-pack.blissful.chatgpt.site, paid per call via x402, $0.08/call, status unknown (last checked 2026-09-15).

Audits a public website URL and returns source-linked facts, conversion checks, and claim-safety notes for AI agents to use safely.

## 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 website-evidence-pack-397225db -d '<json body>'
```

Example prompt: Can you audit the homepage at https://acmecorp.com — pull out all the source-linked facts, check whether there's a clear call-to-action, and tell me what claims are safe to make about them?

## When to prefer this

Choose this endpoint when an AI agent needs grounded, source-linked facts about a website before writing copy, making claims, or doing due diligence — especially when claim safety is important. It is preferable over generic web scrapers because it explicitly outputs claim_safety guidance and conversion checks alongside raw evidence, reducing hallucination risk. Best suited for single-site audits of up to 4 pages; not designed for bulk crawling or deep site indexing.

## Known failure modes

- URL is not publicly accessible or returns non-200 status — crawl may return empty evidence
- robots.txt disallows crawling — endpoint respects robots and may return limited data
- URL points to a non-HTML resource (PDF, image) — parsing fails or returns minimal results
- max_pages exceeds maximum of 4 — validation error returned
- Malformed or non-absolute URL — schema validation rejects the request
- Site uses heavy JavaScript rendering — static crawl may miss dynamically loaded content
- Payment of $0.25 USDC not received — x402 payment required error before audit begins

## How this service works

Focused x402 tools for website CRO audits, public company contacts, exact claim evidence checks, and source-linked research. From $0.02 USDC on Base.

## Output

Returns a structured JSON object containing: an overall trust score (0-100), a list of evidence items with direct quotes and source URLs, conversion check results (pass/fail/severity/fix), claim_safety guidance listing safe hooks and things not to claim, business metadata (name, services, contacts), technical signals (HTTPS, H1 count, canonical, structured data), and crawl metadata including pages audited.
