# ip-listed-on-psbl-bulk

> ip-listed-on-psbl-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 PSBL (Passive Spam Block List) DNSBL in a single concurrent call, returning ordered results with per-item error fields and a failure count.

## Facts

- Endpoint: GET https://ip.intel.rallylive.ca/bulk/ip/blacklist/psbl?utm_source=zero.xyz
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/ip-listed-on-psbl-bulk-79d971f9
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Argn4rBqx5h3GXNQIx1ZC

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 ip-listed-on-psbl-bulk-79d971f9
```

Example prompt: Check all of these IPs against the PSBL spam blacklist in one go: 192.168.1.1, 10.0.0.1, 203.0.113.5, 198.51.100.7, and 185.220.101.1 — tell me which ones are listed and flag any errors.

## When to prefer this

Choose this endpoint when you have a list of 2–20 IPv4 addresses to check against PSBL and want to minimize API round-trips and cost. It processes items concurrently so total latency is roughly the same as a single lookup. Prefer the single-IP endpoint when you have just one address. Use this over the watch variant when you want a one-time snapshot rather than change detection.

## Known failure modes

- Exceeding 20 IPs per batch returns an error or truncates results
- Individual IP lookup failures are surfaced per-item rather than failing the whole batch
- Malformed IP addresses in the input produce per-item error responses
- DNSBL upstream timeouts may cause per-item failures with non-zero failure count
- GET method required; other HTTP methods rejected

## How this service works

Bulk ip listed on psbl: 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 results matching the input IP list, where each item contains the PSBL listing status (same detail as the single-IP endpoint), a per-item error field if the lookup failed, and an overall failure count for the batch.
