## 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-uceprotect-3-bulk-checker-c6f7bdc1
```

Example prompt: Can you check all 15 of our outbound mail server IPs against the UCEPROTECT Level 3 blacklist in one go and tell me which ones are listed and if any lookups failed?

## When to prefer this

Use this endpoint when you have a list of 2–20 IP addresses that all need to be checked against UCEPROTECT Level 3 simultaneously, rather than making separate single-IP calls. It is more cost-efficient and faster than sequential single lookups for batch workflows such as pre-campaign email deliverability audits, bulk onboarding vetting, or incident triage across an IP range. Prefer the single endpoint if you only need to check one IP at a time.

## Known failure modes

- Individual IP lookup fails — per-item error field is populated while other results remain valid
- More than 20 IPs submitted — batch limit exceeded, request rejected
- Invalid IP address format in list — item returns error
- UCEPROTECT-3 service unreachable — all items may return errors with high failure count
- Payment not fulfilled — x402 payment required error before processing begins

## How this service works

Bulk ip listed on uceprotect 3: 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

Returns an ordered array of results matching the input IP list. Each item contains the UCEPROTECT-3 blacklist status for that IP (listed or not), a per-item error field indicating if the individual lookup failed, and an overall failure count summarizing how many items could not be checked.
