# is-ip-vercel-bulk

> is-ip-vercel-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 IP addresses in one call to determine if each belongs to Vercel's infrastructure, returning ordered results with per-item error fields and a failure count.

## Facts

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

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_pyfgYp_oY1w8Q7juz8xhE

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-vercel-bulk-7c4899d7
```

Example prompt: Can you check this batch of IP addresses and tell me which ones belong to Vercel's infrastructure? Here's my list: 76.76.21.21, 64.29.17.1, 198.51.100.5, 203.0.113.10.

## When to prefer this

Use this endpoint when you have a list of 2–20 IP addresses and need to determine Vercel infrastructure membership efficiently in a single API call with concurrent processing, rather than issuing individual single-IP lookups. Prefer this over the single-IP endpoint whenever you hold a batch of IPs to classify, as it reduces latency, API call overhead, and cost per IP. Choose this over generic WHOIS or ASN lookups when you specifically need Vercel detection with structured per-item error handling.

## Known failure modes

- Invalid or malformed IP address in the list causes a per-item error with the failure count incremented
- Batch exceeds 20 IPs resulting in a request rejection or truncation
- Network timeout when querying IP classification services upstream
- Payment failure via x402 protocol blocking the request
- Empty input list returning no results

## How this service works

Bulk is ip vercel: 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 corresponding to each input IP, where each item includes a boolean indicating whether the IP belongs to Vercel's infrastructure, a per-item error field if the lookup failed for that entry, and an overall failure count for the batch.
