# ip-listed-on-mailspike-bulk

> ip-listed-on-mailspike-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 2026-10-12).

Batch checks up to 20 IPv4 addresses against the Mailspike DNSBL blacklist in a single concurrent call, returning per-item results in input order.

## 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-mailspike-bulk-3b2ef820
```

Example prompt: Check all 15 IPs in my list against the Mailspike blacklist at once and tell me which ones are flagged and how many checks failed: 192.168.1.1, 10.0.0.1, 203.0.113.5 ... (up to 20 IPs).

## When to prefer this

Use this endpoint when you have a list of 2–20 IPv4 addresses to check against Mailspike and want to minimize round-trips and cost — one $0.10 batch call instead of multiple single-IP calls. Prefer the single-IP endpoint only when checking one address at a time in real-time.

## Known failure modes

- One or more IPs exceed the 20-item batch limit, causing rejection
- Malformed IP addresses cause per-item errors with that item's error field populated
- DNSBL upstream timeout increases the failure count for affected items
- Payment of 0.10 USDC not provided or declined, resulting in 402 response
- Empty input list returns an error

## How this service works

Bulk ip listed on mailspike: 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, each containing the Mailspike blacklist status (listed/not listed) and any per-item error. Also includes a top-level failure count indicating how many individual checks encountered errors.
