Lyrics

[Verse 1]
Building bridges for your data flow
APIs connect what users need to know
REST is simple, HTTP's way
Get and post and put all day
URLs that make sense when you read
Resources mapped to what you feed

[Chorus]
Design it right from the very start
Version control is API art
REST for web, GraphQL for queries precise
gRPC when speed is worth the price
Test your contracts, keep them strong
APIs that last and serve you long

[Verse 2]
GraphQL gives you power to choose
Fetch exactly what you'll use
No more over-fetching pain
Single endpoint, data gain
Schema first, then build your way
Types defined for every day

[Chorus]
Design it right from the very start
Version control is API art
REST for web, GraphQL for queries precise
gRPC when speed is worth the price
Test your contracts, keep them strong
APIs that last and serve you long

[Bridge]
When you need to change your mind
Version numbers help you find
Backward compatibility
Forward thinking strategy
Headers tell the client which
Version makes the perfect switch

[Verse 3]
gRPC for systems talking fast
Binary protocol built to last
Service definitions clear and bright
Protocol buffers done just right
Contract testing every call
Catch the breaks before they fall

[Chorus]
Design it right from the very start
Version control is API art
REST for web, GraphQL for queries precise
gRPC when speed is worth the price
Test your contracts, keep them strong
APIs that last and serve you long

[Outro]
Document well and test with care
APIs that developers love to share
Three approaches, one simple goal
Connect the world, API soul
