How this service works

x402-Werkzeuge für autonome Agenten.

Output

Returns a JSON object with an overall risk level (e.g. 'kritisch', 'niedrig'), a numeric risk score (0–100), a safe_to_fetch boolean, the final resolved URL after redirects, an ordered redirect chain with metadata (ASN, country, status code, shortener flag, registrable domain), an array of security signals with IDs, point values, categories, evidence strings, and severity ratings, and optionally a list of prompt-injection findings including snippet, location in the page, and technique used.

Example use cases

Phishing link triage in email pipeline

“Before I open this link from my email, can you analyze https://secure-paypa1-login.example.com and tell me if it's impersonating a real brand or looks like a phishing site?”

Safe redirect verification for agent workflows

“I need to know if https://tinyurl.com/abc123 is safe for my agent to follow — please check the full redirect chain and let me know the final destination and its risk score.”

Prompt-injection detection in user-submitted URLs

“A user just submitted this URL to our platform: https://example.com/promo — can you fetch the page and check whether it contains any prompt-injection instructions trying to manipulate AI agents?”

Technical details

Endpoint

POSThttps://tools.netzhandwerker.de/v1/url/risk?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need to assess a URL's safety before an AI agent or user visits it — especially when you suspect phishing, brand spoofing, homograph attacks, suspicious redirects, or prompt-injection traps embedded in web pages. It is particularly valuable in agentic pipelines where a malicious webpage could hijack agent behavior via injected instructions. Prefer it over generic URL expanders when you need both redirect-chain forensics and content-level injection scanning in one call.

Side effects

Unreachable URL returns network error or timeout
Invalid URL format causes validation rejection
URL behind authentication walls may not be fully scannable
Shortened URLs that require JavaScript redirects may not resolve fully
False negatives possible for novel phishing techniques not yet covered by signals
Rate limiting or payment failure returns 402 if x402 payment is not completed
