How this service works
Call when an agent needs src attributes of //source via //source/@src from a public page or HTML (SSRF-safe). Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/xpath-source-src first.
Output
Returns a list of `src` attribute values extracted from all `//source` elements found via XPath in the given webpage or HTML. Each value is a URL string pointing to a media resource referenced in a source tag.
Example use cases
Extract video source URLs from media page
“Go to https://video-site.com/watch?id=abc123 and pull out all the src attributes from the source elements on that page — I want to know what video file URLs are being served.”
Parse HTML snippet for audio sources
“I have this chunk of HTML from a podcast player page — can you extract all the src attributes from the source elements in it? Here's the HTML: <video><source src="/ep1.mp3" type="audio/mpeg"><source src="/ep1.ogg" type="audio/ogg"></video>”
Audit media sources on a public article
“Check https://news-site.com/article/456 and tell me all the src values from any source elements — I'm trying to audit what media files they're loading.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/xpath-source-src?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract `src` attributes specifically from `//source` HTML elements on a public page or from a known HTML string, without writing your own XPath or web-fetching logic. Prefer the free `/v1/sandbox/xpath-source-src` variant first for testing. Choose this over generic scraping tools when you only need source-element src values and want a lightweight, SSRF-safe, paid API call at a fixed $0.008 USDC cost.
Side effects
- URL is unreachable or returns a non-200 status — extraction fails with an error
- SSRF protection blocks the URL if it resolves to a private/internal IP range
- HTML is malformed or contains no source elements — returns an empty list
- HTML string exceeds the 200,000 character limit — request rejected
- URL or HTML not provided — schema validation error
- Page requires authentication or JavaScript rendering — content may be incomplete
