# is-port-443-open-bulk

> is-port-443-open-bulk is a paid API for AI agents from ip.intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-11).

Checks whether TCP port 443 (HTTPS) is open on up to 20 hosts in a single concurrent batch call, returning ordered results with per-item error fields.

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 is-port-443-open-bulk-d31dff01
```

Example prompt: Check whether port 443 is open on these 5 hosts all at once: 192.168.1.1, 10.0.0.1, example.com, api.myservice.io, and backup.myservice.io — I need results in the same order I listed them.

## When to prefer this

Use this endpoint when you have a list of 2–20 hosts that all need a port 443 check and you want results in a single concurrent call rather than making individual requests sequentially. Preferred over the single-host endpoint when processing batches to reduce latency and API call overhead. Ideal for infrastructure audits, pre-deployment checks, monitoring pipelines, and compliance scans where multiple hosts must be evaluated together.

## Known failure modes

- Host unreachable or DNS resolution failure — per-item error field populated, host counted in failure count
- Batch exceeds 20 hosts — request rejected or truncated
- Network timeout on individual hosts — reflected as per-item error rather than batch failure
- Invalid hostname or IP format — per-item error returned
- Payment failure (x402) — entire batch call rejected before processing

## How this service works

Bulk is port 443 open: up to 20 hosts 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 matching the input host list, where each item indicates whether port 443 is open or closed on that host, along with a per-item error field for any hosts that could not be reached or evaluated. Also includes an overall failure count for the batch.
