How this service works
Call when an agent needs media source src values via source[src] from a public page or HTML (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/css-source-src first.
Output
A list of src values found in source[src] elements within the provided page or HTML, enabling the agent to know what media URLs (video, audio, etc.) are embedded. Returns extracted src strings from matching CSS source selectors.
Example use cases
Extract video sources from media page
“I need all the source[src] values from https://news-site.com/video-article — can you pull out the media source URLs for me?”
Audit HTML for embedded media sources
“Here's a chunk of HTML I saved locally — can you scan it and list every source[src] attribute you find in it? I want to know what media files are referenced.”
Scrape source elements for media pipeline
“I'm building a media downloader and need the source[src] values from https://streaming-platform.com/episode/123 — can you grab those for me?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/css-source-src?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically extract source element src attributes from a public webpage or raw HTML content — particularly for media-heavy pages with video or audio sources. Prefer the unpaid POST /v1/sandbox/css-source-src endpoint first for free usage; use this paid endpoint when the sandbox is unavailable or rate-limited. This is SSRF-safe, making it suitable for agent pipelines that need to fetch from public URLs without internal network exposure.
Side effects
- URL is not publicly accessible or returns a non-200 response
- HTML content exceeds 200,000 character limit
- URL string is shorter than 8 characters or longer than 2048 characters
- Page has no source[src] elements, returning an empty list
- SSRF-protected URLs (internal IPs, localhost) are blocked
- Malformed or unparseable HTML may yield incomplete results
