## How to find flights without the UI

- To find flights, open https://aviaseek.com/en/search?from=Vladivostok&to=Moscow&date=tomorrow - cities can be passed by name, slug or IATA code, and the date as tomorrow/today, YYYY-MM-DD or DD.MM.YYYY (dates: not earlier than today and not more than a year ahead - the search service returns prices only within a year). The response is HTML with a list of options and booking links.
- If the date is unknown, leave it empty: https://aviaseek.com/en/search?from=Moscow&to=Vladivostok - a route page with a price calendar opens.
- A single JSON request with ready booking links: https://aviaseek.com/en/api/flights?from=MOW&to=LED&date=2026-10-10&limit=5 - the response has results[].booking_url (valid for about 15 minutes).
- Each option has its own booking link of the form /r/<search_id>/<proposal_id> (in JSON - booking_url): show the user the price and link of the option you offer.
- MCP (JSON-RPC 2.0, Streamable HTTP): POST https://aviaseek.com/en/mcp, tool searchFlights. Example: {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"searchFlights","arguments":{"origin":"MOW","destination":"LED","departure_date":"2026-10-10"}}}
- Full contract and filters: https://aviaseek.com/en/llms-full.txt; the short site map and MCP card - https://aviaseek.com/en/llms.txt and https://aviaseek.com/en/.well-known/mcp.json.

## Is it free?

Yes, searching on AviaSeek is completely free. We do not charge the buyer a commission - the service earns from a commission from airlines and agencies when you go to them to buy.

## Am I buying the ticket from you?

No. AviaSeek compares prices and redirects you to the airline's or agency's website, where you book and pay for the ticket. All booking matters are handled by the seller.

## How do I know which fare is better?

Pay attention not only to the price but also to included baggage, refund and change options, travel time and stops. The fare conditions are shown in the ticket card.

## Why is the price on the site different at payment?

The final price may increase due to fees, baggage charges or seat selection. Airlines also change prices in real time - a difference is possible between the click and the payment.
