Checks and signals

Each line is separate evidence, not a trust score.

  • Passed Endpoint answered the live check ·
  • Passed Official MCP Registry namespace is tied to canienter.com ·
  • Passed Endpoint is on the registry namespace domain ·
  • Availability 1 of 1 checks passed in 30 days

What you can do with it

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Stateless visa/entry-requirements lookups. check_entry_requirements is rate limited on the free tier; for unlimited access pay per request via x402 on the HTTP API (see the llms.txt of this host). Advisory information for trip planning — not a boarding, immigration, or legal decision. Rules change frequently; verify with the destination country's official sources before travel.

check_entry_requirements — Check entry requirements
Advertised by the server during the last successful anonymous check.
Advertised read-only

Whether a passport holder can enter a destination country: visa-free, visa on arrival, e-visa, eTA, or visa required — with allowed stay, official application portal, extended rules (passport validity, onward ticket, yellow fever, transit-without-visa) and source citations. Free tier: rate limited per caller (see /auth.md to register for a larger quota, or use the x402-paid HTTP API for unlimited access).

evaluate_trip — Evaluate a full trip (paid)
Advertised by the server during the last successful anonymous check.
Advertised read-only

Premium evaluation of a whole trip in one call: multiple passports (best passport per leg), documents held, multi-leg itineraries with transit legs, dates and purpose — with structured why[] explanations, conditions[], and verification states per decision. PAID endpoint: the call returns HTTP 402 x402 payment instructions unless the request carries an x402 payment header; any x402-capable client settles in USDC on Base and retries.
