## 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 lilambd-pet-entry-rules-lookup-cd45926c
```

Example prompt: What do I need to bring my dog from the US to Germany — we're arriving in 30 days and his vaccines were done here in the US?

## When to prefer this

Use this endpoint when you need authoritative, country-specific pet import rules for dogs, cats, or ferrets, especially when the origin country and time-to-arrival are known. It handles EU member state normalization (any EU ISO2 maps to EU rules) and US vaccination origin distinctions, making it more precise than generic travel advice for pet owners crossing international borders.

## Known failure modes

- Missing required 'to' parameter returns an error
- Unsupported destination country ISO2 code may return no results or an error
- Invalid species value (not dog, cat, or ferret) may return an error or empty rules
- Insufficient days value may cause unexpected routing of requirements
- Payment failure via x402 protocol returns 402 Payment Required

## How this service works

A crossing for play, feeling, language, science and computation — creating states that do not have names yet.

## Output

A JSON object containing the pet entry requirements for the specified destination country, including required vaccinations, documentation, waiting periods, quarantine rules, and any species- or origin-specific conditions (e.g. US-vaccinated vs foreign-vaccinated animals).
