# is-port-636-open-bulk

> is-port-636-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).

Bulk-checks whether TCP port 636 (LDAPS) is open on up to 20 hosts in a single concurrent API call, returning per-host results in input order with error details and a failure count.

## Facts

- Endpoint: GET https://ip.intel.rallylive.ca/bulk/ip/port/636?utm_source=zero.xyz
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/is-port-636-open-bulk-86818b3e
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Qly0qGs2hFz3c-v9o6OOg

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-636-open-bulk-86818b3e
```

Example prompt: Can you check whether port 636 is open on all 15 of our LDAP servers — here's the list of IPs — and tell me which ones are reachable and which ones failed?

## When to prefer this

Use this endpoint when you need to check port 636 (LDAPS) status on multiple hosts (2–20) in a single call instead of making repeated single-host requests. Ideal for batch enrichment workflows, infrastructure audits, or compliance scans where concurrency and ordered results matter. Prefer the single-host endpoint only when checking one IP at a time.

## Known failure modes

- Input list exceeds 20 hosts — batch limit enforced
- Individual host unreachable or DNS resolution failure — per-item error field populated
- Invalid host format causes item-level error without failing the whole batch
- Network timeout on a specific host returns error in that item's slot
- Payment failure (x402) blocks the entire call

## How this service works

Bulk is port 636 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 list of per-host results matching the input order, each containing whether port 636 is open or closed, a per-item error field if the probe failed, and an aggregate failure count across the batch.
