# ip-listed-on-spamrats-noptr-bulk

> ip-listed-on-spamrats-noptr-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 2026-10-13).

Bulk-checks up to 20 IPv4 addresses against the SpamRATS NOPTR DNSBL in a single concurrent call, returning per-IP listing status and a failure count.

## 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 ip-listed-on-spamrats-noptr-bulk-afc73814
```

Example prompt: I have a list of IPs — 198.51.100.1, 203.0.113.5, 192.0.2.44, and 10.0.0.2 — can you batch check all of them against the SpamRATS NOPTR blacklist and tell me which ones are listed?

## When to prefer this

Prefer this endpoint when you have a list of 2–20 IPv4 addresses to check against SpamRATS NOPTR and want to minimize API calls and latency by processing them concurrently in one batch. Use the single-IP endpoint if you have only one address to check. Choose this over generic IP reputation services when you specifically need SpamRATS NOPTR (no-PTR-record spam source) classification.

## Known failure modes

- DNS resolution timeout for one or more IPs — item-level error field is populated, failure count incremented
- Invalid IP address format in input — per-item error returned
- Batch exceeds 20 IPs — request may be rejected or truncated
- Network connectivity issue to DNSBL server — failure reflected in per-item error
- Payment of 0.10 USDC not completed — 402 Payment Required response returned before any lookups

## How this service works

Bulk ip listed on spamrats noptr: up to 20 ips 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 per-IP results matching the input list order, each containing whether the IP is listed on the SpamRATS NOPTR DNSBL, a per-item error field indicating any lookup failure, and a top-level failure count summarizing how many items could not be resolved.
