## 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 agentshelf-ipv6-regex-extractor-334aee44 -d '<json body>'
```

Example prompt: Can you extract all the IPv6 addresses from this server log text for me? Here's the log: '2001:db8::1 connected at 10:42, fe80::1%eth0 disconnected, and 2001:0db8:85a3:0000:0000:8a2e:0370:7334 attempted auth.'

## When to prefer this

Use this endpoint when you need to extract IPv6 addresses (and only IPv6 — not IPv4) from unstructured text without performing any network requests or DNS lookups. Prefer the free sandbox endpoint POST /v1/sandbox/regex-ipv6 for testing before spending $0.001 USDC per call. Choose this over a general regex service when you want a narrowly scoped, IPv6-specific extractor.

## Known failure modes

- Empty match list returned if no IPv6 addresses present in text (still billed)
- Cap of 20 matches — additional IPv6 addresses beyond 20 are silently dropped
- Input text exceeding 100,000 characters rejected
- Empty or missing text field rejected (minLength:1)
- Payment failure if USDC balance insufficient

## How this service works

Call when an agent needs IPv6 addresses extracted from text, capped at 20 matches. An empty match list is billed. No network. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/regex-ipv6 first.

## Output

Returns a list of up to 20 matched IPv6 addresses found in the input text. If no IPv6 addresses are present, an empty list is returned — and the call is still billed at $0.001 USDC.
