# is-ip-heroku-bulk

> is-ip-heroku-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).

Checks up to 20 IPv4 addresses in a single concurrent batch call to determine whether each is announced by Heroku's ASN, returning ordered results with per-item errors and a failure count.

## Facts

- Endpoint: GET https://ip.intel.rallylive.ca/bulk/ip/is/heroku?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/is-ip-heroku-bulk-74303ead
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_wK_FPo_0Faa9RvhUBCacc

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-ip-heroku-bulk-74303ead
```

Example prompt: Check this batch of IPs for me — 54.236.1.1, 50.19.100.200, 23.21.77.44, 54.144.5.9, and 107.21.214.90 — and tell me which ones are Heroku addresses, along with any that couldn't be checked.

## When to prefer this

Choose this endpoint when you have 2–20 IPv4 addresses to check for Heroku hosting and want to minimize round-trips and cost compared to calling the single-IP endpoint repeatedly. It is ideal for log enrichment pipelines, security triage workflows, or any agent that accumulates a list before processing. For a single IP, prefer the single endpoint; for more than 20, split into multiple batch calls.

## Known failure modes

- Invalid or malformed IPv6/non-IPv4 addresses in the batch return per-item errors
- Batch size exceeding 20 IPs may be rejected or truncated
- Individual IPs that time out during ASN resolution contribute to the failure count
- Payment failure (x402) prevents the entire batch from being processed
- Network errors contacting Team Cymru DNS for specific IPs result in per-item error fields

## How this service works

Bulk is ip heroku: 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 same Heroku ASN detection answer as the single-IP endpoint, plus a per-item error field if that check failed; also includes a top-level failure count indicating how many items encountered errors.
