How this service works
Call when an agent needs script sources via script[src] from a public page or HTML (SSRF-safe). Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/css-script-src first.
Output
A JSON array or structured list of script[src] attribute values found within the page or HTML, representing all external and inline JavaScript source URLs referenced in script tags. The response is SSRF-safe, meaning server-side request forgery vectors are mitigated by the provider.
Example use cases
Third-party script audit for security
“I need to audit the external scripts loaded by https://shop.acme.com — can you extract all the script src URLs so I can check for any suspicious or unexpected third-party JavaScript?”
JavaScript dependency discovery from raw HTML
“I have this HTML snippet from a competitor's page and I want to know which JavaScript libraries they're using — can you parse out all the script src attributes from it?”
CSP policy generation preparation
“I'm building a Content Security Policy for https://myblog.example.com and need a full list of every script source the page currently loads — can you get those for me?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-script-src?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically extract script[src] URLs from a public webpage or arbitrary HTML string in an SSRF-safe way. It is purpose-built for JavaScript source discovery rather than general HTML parsing. Prefer the free POST /v1/sandbox/css-script-src endpoint first if available; fall back to this paid endpoint at $0.007 USDC when the sandbox is unavailable or rate-limited. Choose this over a full-page scraper when you only care about script sources, not full page content.
Side effects
- URL is unreachable or returns non-200 status — endpoint may return an error or empty result
- HTML input exceeds 200,000 character limit — request rejected
- URL string shorter than 8 characters or longer than 2,048 characters — validation error
- Page has no script[src] tags — returns empty list
- SSRF-restricted URL (private IP ranges, localhost) — blocked by safety filter
- Malformed HTML — parser may miss some tags or return partial results
