## 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 alion-company-visa-sponsor-lookup-540e036c
```

Example prompt: Does Stripe sponsor H-1B visas? Look up their visa sponsorship data — I want to know how many H-1B and green card filings they made in the last 12 months and what the median offered wage is.

## When to prefer this

Use this endpoint when you need structured, quantitative H-1B and green card sponsorship data for a specific company — including filing counts, wage data, and licensed sponsor status. Prefer this over general web search when you need machine-readable data suitable for comparison, filtering, or downstream processing. Ideal for job seekers evaluating visa sponsorship prospects, immigration attorneys, and recruiters benchmarking compensation.

## Known failure modes

- Company not found in Alion database — returns empty or null visa array
- Missing or invalid API key — returns 401 Unauthorized
- Insufficient credits — returns 402 Payment Required with x402 payment offers
- Ambiguous company name with no domain/URL provided — may return wrong entity
- Company exists but has no visa filing history — visa array returns empty
- Invalid query parameter types — returns 400 Bad Request

## How this service works

Plain-HTTP twin of the Alion MCP server. Every tool is also a GET/POST endpoint. Send "Authorization: Bearer <key>" (a key from https://alion.io/developers/keys); calls are paid from the account's credits. Or pay a paid tool per call in USDC with x402 (https://x402.org), no account: call it without a key, sign one of the offers in the PAYMENT-REQUIRED header of its 402 and repeat the call with the PAYMENT-SIGNATURE header; or with MPP (https://paymentauth.org): answer a WWW-Authenticate: Payment challenge with Authorization: Payment <credential> (USDC on Base or Solana, a transfer you sign or have sent).

## Output

Returns a JSON object containing the company's name, domain, website, industry, size band, and headquarters location, plus a visa array with per-country sponsorship data including H-1B filing count in the last 12 months, green card filing count, median offered wage in USD, and whether the company is a licensed sponsor.
