How this service works
Call when an agent needs JSON-LD @type Course extracted from a public page or HTML (SSRF-safe). Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/profile-jsonld-course first.
Output
Returns the extracted JSON-LD @type Course object(s) from the page, containing fields such as name, description, provider, url, courseCode, hasCourseInstance, and other schema.org Course properties found in the page's structured data markup.
Example use cases
Scrape course metadata from Coursera
“Grab the JSON-LD Course schema from https://www.coursera.org/learn/python — I need the course name, description, and who offers it according to the page's structured data.”
Extract course schema from raw HTML
“I have the HTML of an online course page — can you extract any JSON-LD @type Course objects from it and give me the structured data?”
Aggregate course details from edX
“Pull the JSON-LD Course structured data from https://www.edx.org/course/introduction-to-computer-science — I want to see whatever schema.org Course metadata is embedded in that page.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-jsonld-course?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract schema.org Course structured data specifically from a public webpage or HTML blob, and you want an SSRF-safe, paid extraction service. Prefer the free sandbox endpoint POST /v1/sandbox/profile-jsonld-course first; fall back to this paid endpoint when the sandbox is unavailable or rate-limited. Choose this over general-purpose scrapers when you specifically need the JSON-LD Course type and want structured, typed output rather than raw HTML or unstructured text.
Side effects
- URL is unreachable or returns non-2xx HTTP status
- Page contains no JSON-LD @type Course markup — returns empty result
- HTML exceeds 200,000 character limit
- URL is blocked due to SSRF safety rules (private/internal addresses)
- Malformed HTML that cannot be parsed
- Both url and html fields absent or too short
