## 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-1-bulk-checker-c3c564c6
```

Example prompt: Can you check all 15 of these IP addresses against the UCEPROTECT Level 1 blacklist at once and tell me which ones are listed and if any lookups failed?

## When to prefer this

Choose this endpoint when you have a list of 2–20 IP addresses and need to check all of them against UCEPROTECT Level 1 in a single API call rather than making individual requests. It is more efficient and cost-effective than chaining single-IP lookups, and is ideal for batch enrichment workflows, pre-send email deliverability checks, and periodic reputation audits of IP pools.

## Known failure modes

- Batch exceeds 20 IPs — only up to 20 IPs are supported per call
- Invalid IP format in the input list causes per-item error for that entry
- UCEPROTECT DNS lookup timeout results in a per-item error and increments failure count
- Missing or malformed input array causes full request failure
- Payment not provided or insufficient USDC results in 402 rejection

## How this service works

Bulk ip listed on uceprotect 1: 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 order, each containing the UCEPROTECT Level 1 blacklist status (listed or not), a per-item error field indicating any lookup failure, plus a top-level failure count summarizing how many items errored across the batch.
