# Regulavita Web Source Snapshot

> Regulavita Web Source Snapshot is a paid API for AI agents from evidence.regulavita.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).

Fetches a public HTTPS web page (HTML, JSON, XML, or text), returns normalized agent-ready text with optional literal-match excerpts, a content hash, and an Ed25519-signed receipt — no API key required.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 regulavita-web-source-snapshot-45304b17 -d '<json body>'
```

Example prompt: Fetch the current content of https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=AAPL&type=10-K&dateb=&owner=include&count=5 and give me a signed snapshot with the full normalized text so I have a verifiable record of what it says right now.

## When to prefer this

Choose this endpoint when you need not just the content of a public web page but also cryptographic proof (Ed25519 signature + content hash) that the content was retrieved at a specific time — ideal for audit trails, compliance evidence, agent accountability chains, or any workflow where you must later prove what a public source said. Prefer it over generic web scrapers when tamper-evidence and signed receipts are required, and over browser automation when a simple normalized-text extraction of a static public page suffices.

## Known failure modes

- Non-HTTPS or non-public URLs rejected — endpoint only serves public HTTPS sources
- Timeouts if the target page is slow or unreachable, returning an error with no receipt
- Pages behind authentication, CAPTCHAs, or JavaScript-only rendering may return empty or partial content
- Very large pages may be truncated before normalization
- Target URL returning non-200 status causes an error response with no signed receipt
- Requested literal-match strings not found in content are reported as absent rather than causing failure

## How this service works

Fetch one public HTTPS HTML, JSON, XML, or text source and return normalized agent-ready text, optional literal-match excerpts, a content hash, and an Ed25519-signed receipt. No account or API key.

## Output

Returns normalized plain text of the fetched page, optional excerpts where requested literal strings appear, a SHA-256 or similar content hash, and an Ed25519-signed receipt that cryptographically attests to the URL, timestamp, and content hash — enabling downstream verification that the content was genuinely retrieved at a specific moment.
