> is-website-up-bulk is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Checks whether up to 20 URLs are online simultaneously, returning up/down status, HTTP status code, and response time for each URL in a single call.

## 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 is-website-up-bulk-9c7fa7c4
```

Example prompt: Can you check if all of these websites are currently up and online — example.com, myblog.org, shopsite.io, and 10 other URLs I have — and tell me which ones are down along with their HTTP status codes and response times?

## When to prefer this

Use this endpoint when you need to check the availability of multiple URLs (up to 20) in a single efficient call rather than making individual requests. It is preferable when you have a batch of URLs to validate simultaneously and want results in the same order as input with aggregated failure counts. It is faster and more cost-efficient than calling the single /is-it-up endpoint repeatedly.

## Known failure modes

- Invalid or malformed URLs return a per-item error with no status code
- More than 20 URLs in a single call may be rejected or truncated
- Timeouts on slow-responding servers may return down status even if site is technically available
- Private or firewalled URLs may appear as down
- DNS resolution failures result in per-item error

## How this service works

Bulk is website up: 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 /is-it-up endpoint (Is this website up? Checks if a URL is online right now and answers up/down with the HTTP status code, response time in ms, final URL after ). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of results matching the input URL order, each containing: up/down status, HTTP status code, response time in milliseconds, and the final URL after any redirects. A top-level failure count summarizes how many URLs are down or errored, and each item includes a per-item error field for any that could not be reached.
