## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability extract-h4-as-json-bulk-08b26e2f
```

Example prompt: I have a list of 15 product pages — can you extract all the H4 headings from each one and give me the results as JSON, with any errors flagged per URL?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
