Returns the entry/visa options for a traveller of a given nationality (passport) going to a destination for a stated purpose and length of stay. Each option includes: visa/permit type, whether a visa is required, maximum stay, whether remote/on-site work is allowed, cost, processing time, and application/renewal notes — sourced from official immigration authorities. Use this for "what visa do I need / can I stay N days / can I work remotely here". To count days already spent against the 90/180 limit use departi_track_schengen; for the tax consequences of staying use departi_check_tax. Tip: nationality should be the traveller's most favorable passport — multi-nationals may have better entry on one passport.

Calculates Schengen 90/180 short-stay status from a list of stays. Returns: days used and days remaining in the rolling 180-day window, a status (safe | warning | critical | exceeded), the projected date the limit would be reached at the current pace, and — for residence/digital-nomad-permit holders — a count that excludes days in the permit-issuing country while still counting every other Schengen state (with a note of which country is excluded). Use for non-EU travellers tracking the 90-days-in-180 limit. Note: EU/EEA nationals have free movement (not counted); a residence permit exempts only its issuing country, not the rest of Schengen.

Assesses tax-residency risk and double-tax-treaty position for a traveller in a destination. Returns: whether the stay risks triggering destination tax residency (the day threshold and the country's day-counting method), the relevant treaty provisions between the traveller's tax-residence country and the destination (employment income, tie-breaker, social security, withholding), any special or digital-nomad tax regime, and — for US citizens — FEIE / Physical-Presence-Test context. Advisory only, not tax advice. Use for "will staying here make me tax resident / what does the treaty say / how are my days counted". Note: any US citizenship triggers worldwide/citizenship-based obligations regardless of residence or other passports.

Searches bookable accommodation in a destination for given dates and returns a ranked list of stays, each with: name, property type, nightly price (in the requested currency), star rating, guest rating, key facilities (e.g. wifi, kitchen), a persona/traveler-type fit score, and a booking deep-link. Curated and scored for the traveller's persona and trip type — e.g. long-stay nomad apartments with kitchen + fast wifi vs weekend hotels. Use when the user needs a place to stay; for getting there use departi_search_transport, for things to do use departi_search_experiences. Returns an empty list if no inventory matches.

Searches flights between two places and returns a ranked list of options, each with: carrier, price (in requested currency), cabin class, total duration, number of stops, departure & arrival times, and a booking deep-link. Flights are sourced across providers (Duffel + Travelpayouts) for broad full-service and low-cost coverage. Use for "how do I get from A to B by air". For where to stay use departi_search_accommodation; for things to do use departi_search_experiences. Prices are indicative — book via the returned link. Returns an empty list if no route is found. Ground/rail/bus is not offered through this tool.

Searches bookable tours, activities and local experiences in a destination and returns a ranked list, each with: title, category (cultural / culinary / adventure / wellness / nature), duration, price (in requested currency), a persona-fit score, and a booking deep-link. Matched to the traveller's persona/personality. Use for "what can I do in X". For a place to stay use departi_search_accommodation; to get there use departi_search_transport. Returns an empty list if nothing matches the filters.

Returns the authenticated user's Departi profile: nationalities, current tax residence, subscription tier, a travel-history summary, and a live compliance snapshot (current Schengen / tax-residency / US-clock status). Requires authentication (OAuth). Use to personalise the other tools' answers, or to answer "where do I stand right now". Read-only; takes no parameters.
