does-site-use-imgix-bulk

Use this endpoint when you have multiple domains (up to 20) to check for imgix usage and want to avoid making 20 sequential single-domain calls. It processes concurrently, returns results in input order, and handles per-item failures gracefully, making it ideal for bulk enrichment workflows, tech stack audits, or sales prospecting pipelines. Prefer the single endpoint for one-off checks; prefer this batch endpoint when throughput and efficiency matter across a list.

• Domain unreachable or times out — per-item error field is populated, failure count incremented
• Invalid or malformed domain in input — item returns error, rest of batch still processed
• Batch exceeds 20 domain limit — request rejected
• Network-level block or bot protection on target site — may produce false negative
• Empty input list — request rejected or returns empty results
