# does-site-use-jsdelivr-bulk

> does-site-use-jsdelivr-bulk is a paid API for AI agents from site.intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-02).

Batch-checks up to 20 domains concurrently to detect whether each site uses the jsDelivr CDN, returning results in input order with per-item error fields and a failure count.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 does-site-use-jsdelivr-bulk-f014f5f8
```

Example prompt: Can you check this list of domains — shopify.com, stripe.com, vercel.com, netlify.com, and github.com — and tell me which ones are using jsDelivr CDN?

## When to prefer this

Choose this bulk endpoint over the single-domain endpoint when you have 2–20 domains to check simultaneously and want results in a single API call with concurrent processing. It is more efficient and cost-effective for batch workflows, tech-stack audits, or enriching a dataset of domains. Use the single endpoint only when checking one domain at a time or when you need to integrate into a loop with per-domain error handling outside of this service.

## Known failure modes

- Domain unreachable or times out — per-item error field populated, counted in failure total
- Invalid domain format causes per-item error
- Batch exceeds 20 domain limit — request rejected
- CDN fingerprint match may produce false negatives if site conditionally loads jsDelivr
- Payment failure (x402) prevents request from being processed

## How this service works

Bulk does site use jsdelivr: up to 20 domains 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 an ordered array of results corresponding to each input domain, where each item contains a boolean indicating jsDelivr usage (matching the single-domain endpoint's answer), a per-item error field if the check failed, and an overall failure count for the batch.
