US work-visa (H-1B and related) applications filed by a public company, sourced from Department of Labor LCA disclosures. Pass ticker and optionally a from/to window (YYYY-MM-DD; defaults to ~2 years); returns each application with job title, SOC code, visa class, case status, wage range, worksite city/state, employment dates, and case number. Use it as a hiring/headcount signal. Data by Finnhub.
/api/stocks/h1b-visasPAYMENT-SIGNATURE.The h1b visas API is a pay-per-call stocks endpoint built for AI agents and autonomous software. US work-visa (H-1B and related) applications filed by a public company, sourced from Department of Labor LCA disclosures.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in h1b visas data source for an agent tool-use loop, an MCP host, or a backend that needs stocks data on demand without onboarding to yet another vendor portal.
