# extract-h3-as-json-bulk

> extract-h3-as-json-bulk is a paid API for AI agents from page.intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-23).

Bulk extracts H3 heading elements as JSON from up to 20 URLs in a single concurrent call, returning results in input order with per-item error fields.

## 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-h3-as-json-bulk-042f86fe
```

Example prompt: Can you pull all the H3 headings as JSON from these 15 URLs at once and give me the results in the same order I provided them?

## When to prefer this

Choose this endpoint when you have a list of 2–20 URLs and need H3 headings from all of them efficiently. It processes requests concurrently and preserves input order, making it far more efficient than calling the single-URL endpoint in a loop. Ideal for bulk SEO audits, content indexing pipelines, and competitive analysis workflows where an agent holds a list of pages.

## Known failure modes

- URL unreachable or returns non-200 status — per-item error field populated, failure count incremented
- Input list exceeds 20 URLs — request may be rejected or truncated
- Page has no H3 elements — returns empty array for that item
- Malformed URL in input list — per-item error with parsing failure
- Network timeout on individual URLs during concurrent processing — error reported per item

## How this service works

Bulk extract h3 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. Each item contains the H3 headings extracted from that page (matching the single-endpoint response format), plus a per-item error field if that URL failed. A top-level failure count summarizes how many items errored.
