## 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 bizintel-api-visa-rules-lookup-2609181d -d '<json body>'
```

Example prompt: Does someone with Indian nationality need a visa to work in the US, and if so what visa class applies?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call programmatic check on visa requirements between two countries without maintaining an API key or subscription. It is well-suited for HR tech agents screening international hires, relocation workflows, or travel pre-authorization checks. Prefer it over manually consulting embassy websites when you need machine-readable output with a confidence score and visa class label. For legal certainty, always follow up with a qualified immigration attorney as the response itself recommends.

## Known failure modes

- Invalid or unsupported 2-character country code returns an error or unsupported flag
- Uncommon origin-destination pairs may return low confidence or incomplete data
- Missing required fields (origin_country or destination_country) causes a 400-level validation error
- Payment failure via x402/USDC results in a 402 Payment Required response
- Data may be stale for rapidly changing visa regimes despite the data_as_of timestamp

## How this service works

Resolves business/work permit requirements and visa rules by nationality and destination country.

## Output

A JSON object indicating whether visa entry is supported/documented, the required visa class (e.g. H-1B, L-1, tourist visa), confidence level (high/medium/low), the data currency date, any warnings, and a legal disclaimer reminding the user this is informational only and not legal advice.
