How this service works
Call when an agent needs iframe sources via iframe[src] from a public page or HTML (SSRF-safe). Send JSON fields html (string). Exact $0.006 USDC on Base. Try unpaid POST /v1/sandbox/css-iframe-src first.
Output
A list of iframe src attribute values found in the page or HTML provided, extracted using the CSS selector iframe[src]. Returns all matching src URLs as strings.
Example use cases
Audit embedded iframes on a page
“Can you scan https://news-site.com/article/123 and give me a list of all iframe sources embedded on that page? I want to see what third-party content they're loading.”
Extract iframes from raw HTML snippet
“I have this HTML from a webpage — can you parse it and pull out all the iframe src values? Here's the HTML: <html><body><iframe src='https://player.vimeo.com/video/123'></iframe><iframe src='https://ads.example.com/banner'></iframe></body></html>”
Detect third-party embeds on landing page
“Check https://marketing-agency.com/landing and tell me all the iframe sources it contains — I'm auditing what external services they've embedded.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-iframe-src?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically extract iframe src attributes from a page or HTML blob in an SSRF-safe environment. Prefer the free sandbox endpoint POST /v1/sandbox/css-iframe-src when available; use this paid endpoint when the sandbox is unavailable or rate-limited. Choose this over full HTML scrapers when you only need iframe sources, not general DOM extraction.
Side effects
- URL is unreachable or returns non-200 — extraction fails with an error
- HTML exceeds 200,000 character limit — request rejected
- URL shorter than 8 characters or not a valid URL — validation error
- No iframe[src] elements found — returns empty list
- SSRF-protected URLs (private IPs, localhost) are blocked — returns an error
- Malformed HTML may cause incomplete extraction
