How this service works
Bulk extract h1 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
A JSON array of results in the same order as the input URLs, where each item contains the extracted H1 text and a per-item error field (null on success). The response also includes an overall failure count indicating how many URLs could not be processed.
Example use cases
SEO audit of competitor pages
“Here are 18 competitor landing page URLs — extract the H1 heading from each one and return them as JSON so I can compare how they're titling their pages.”
Content pipeline URL enrichment
“I'm building a content database and I have a batch of 20 article URLs — grab the H1 from each page concurrently and give me the results in order, noting any that couldn't be fetched.”
Broken heading detection across site
“Can you check these 12 URLs from our staging site and extract the H1 from each one? I want to see which pages are missing a heading or returning an error.”
Technical details
Endpoint
GEThttps://page.intel.rallylive.ca/bulk/page/h1/json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have a list of 2–20 URLs and need H1 headings from all of them efficiently in a single API call. It is preferable over calling the single-URL endpoint in a loop because it processes concurrently, returns results in input order, and handles per-item failures gracefully without aborting the entire batch. Ideal for SEO pipelines, content enrichment workflows, or any agent task where heading data from multiple pages is needed at once.
Side effects
- URL unreachable or returns non-200 status — per-item error field populated, counted in failure count
- Page has no H1 element — per-item result may be null or empty
- Exceeding 20 URL limit — request may be rejected or truncated
- Network timeout on a specific URL — that item fails gracefully while others succeed
- Malformed URL in list — per-item error field indicates parse failure
