How this service works
Bulk extract h4 as json: up to 20 urls in one call, processed concurrently, results in input order with a per-item error field and a failure count. Same answer per item as the single endpoint. Batch enrichment for agents that hold a list. $0.10 per batch.
Output
Returns a JSON array with one entry per input URL, each containing the extracted H4 heading elements as a JSON array (matching the single-URL endpoint output), a per-item error field if the page failed to load or parse, and a top-level failure count summarizing how many URLs encountered errors.
Example use cases
SEO audit across competitor pages
“I have a list of 12 competitor landing pages — pull all the H4 headings from each one and return them as JSON so I can compare how they structure their content.”
Content inventory for site migration
“Here are 18 URLs from our old website — extract every H4 heading from each page and give me the results in order with any failures noted, so I can map the content structure.”
Research aggregation from article list
“I've got 20 blog post URLs I want to analyze — can you batch-fetch all the H4 subheadings from each article and return the JSON results with a count of how many pages failed?”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/bulk/page/h4/json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have a list of 2–20 URLs and need H4 headings from all of them efficiently. It processes URLs concurrently and returns results in input order, making it far more efficient than calling the single-URL endpoint repeatedly. Ideal for batch SEO audits, content inventories, or any workflow where an agent holds a list of pages to enrich.
Side effects
- URL unreachable or returns non-200 status — per-item error field populated, failure count incremented
- Page has no H4 elements — returns empty array for that item
- More than 20 URLs submitted — request may be rejected or truncated
- Malformed URL in input list — per-item error field populated
- Network timeout on a specific URL — per-item error reported, others still processed
