Current US State Department travel advisories. Omit country for the full list (every country with an active advisory), or pass country (name, case-insensitive substring) for one. Each entry returns the country, the advisory level (1 Exercise Normal Precautions, 2 Exercise Increased Caution, 3 Reconsider Travel, 4 Do Not Travel) with its label, a plain-text summary of the reasons (crime, terrorism, unrest, kidnapping, health, etc.), the official advisory link, and the published date. Sourced live from the official travel.state.gov RSS feed (US government, public domain). For trip planning, duty-of-care, and travel-risk screening.
/api/travel/advisoryPAYMENT-SIGNATURE.The advisory API is a pay-per-call travel endpoint built for AI agents and autonomous software. Current US State Department travel advisories.
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 advisory data source for an agent tool-use loop, an MCP host, or a backend that needs travel data on demand without onboarding to yet another vendor portal.
