## 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 heading-audit-bulk-e6532dee
```

Example prompt: Can you run a bulk H1 heading audit on these 15 URLs for me and tell me which ones have missing, duplicate, or malformed H1 tags, along with any errors?

## When to prefer this

Choose this endpoint when you have a list of 2–20 URLs that all need heading structure audits and you want to minimize round trips and processing time. It is strictly better than calling the single /site/h1-audit endpoint repeatedly when working with multiple URLs, and returns results in deterministic input order with per-item error isolation so a single bad URL does not block the rest.

## Known failure modes

- Individual URL fetch failure returns a per-item error rather than crashing the batch
- URLs that time out or return non-200 responses are flagged in the error field
- More than 20 URLs submitted may be rejected or truncated
- Malformed URL input may cause item-level errors
- Pages with no H1 tags will be reported as such rather than as errors

## How this service works

Bulk heading audit: up to 20 urls in one call, processed concurrently, results returned in input order with a per-item error field and a count of failures. Same answer per item as the single /site/h1-audit endpoint (Heading structure audit). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of per-URL heading audit results matching the input list, each containing the same H1 structure audit data as the single-URL endpoint, a per-item error field indicating any fetch or parse failures, and a summary count of total failures across the batch.
