# is-port-993-open-bulk

> is-port-993-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 993 (IMAPS) is open on up to 20 hosts concurrently in a single API call, returning ordered results with per-item error fields and a failure count.

## Facts

- Endpoint: GET https://ip.intel.rallylive.ca/bulk/ip/port/993?utm_source=zero.xyz
- Price: $0.1/call
- Payment: x402
- Status: unknown

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_24iQVifcflBZ1HdbeGO0O

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-993-open-bulk-5ef137c4
```

Example prompt: Check whether port 993 (IMAPS) is open on all 20 of these mail server hostnames at once and tell me which ones are reachable and which failed.

## When to prefer this

Choose this endpoint when you have a list of 2–20 hosts and need port 993 status for all of them in a single round-trip rather than making sequential single-host calls. It processes concurrently and preserves input order, making it ideal for batch enrichment pipelines, fleet audits, or any workflow where latency savings from parallelism matter.

## Known failure modes

- Host unreachable or DNS resolution failure returns a per-item error with closed/unknown status
- Batch exceeds 20 hosts — request rejected or truncated
- Network timeout at Cloudflare edge returns error for that item
- Invalid hostname format causes per-item error
- Payment failure (x402) prevents the call from executing

## How this service works

Bulk is port 993 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

An ordered array of results matching the input host list, where each item contains the open/closed status of port 993, a per-item error field if the check failed, and an overall failure count for the batch.
