Assumptions:

• I set timeout for each API request to .8 to keep my service live.
• I relayed on filesystem as a fallback s1-response.json, s2-response.json in case the APIs down or exceed the timeout limit, so the system can switch between fetching the data from the APIs to filesystem on runtime based on APIs' availabilities and timeout limit constrains.
• I used Symfony Service Tag to automatically inject advertisers who implement AdvertiserInterface. But if we have a lot of advertisers we can list them in DB.

Criteria/Filters Examples:

• example http://localhost:8001/api/rooms?sortByPrice=asc&maxPrice=160&minPrice=150
• minPrice /api/rooms?minPrice=150 requirements="\d+"
• maxPrice /api/rooms?minPrice=167 requirements="\d+"
• sortByPrice /api/rooms?sortByPrice=asc requirements="[a-z]+"
• code /api/rooms?code=FUBOD requirements="[a-z]+"
