11. Would it be nice?
All APIs descriptions in one place
Documented in one format
Anyone can add/improve API description

12. What APIs.guru do?
Filter out private and non-reliable APIs.
Convert different formats into Swagger 2.0
Fix mistakes, ~80% of spec have them
Add additional data, like: logo, categories, …

14. Any-API.com

15. SDKs.io

16. CenitSaaS.com

17. commandcar

18. DataFire.io

19. Why not Hypermedia?
Cool technology, but doesn’t help iPaaS:
Can access metadata only after first call
Metadata only for particular entities
Require API owner to change implementation

20. Far Far Future: Synergy

21. Data incompatibility
{
“First name”: “John”,
“Surname”: “Smith”
}
{
“Name”: “John”,
“Surname”: “Smith”
}
{
“Full name”: “John Smith”
}

22. Schema incompatibility
{
“properties”: {
“First name”: {
“type”: “string”
},
“Surname”: {
“type”: “string”
}
}
}
{
“properties”: {
“Name”: {
“type”: “string”
},
“Surname”: {
“type”: “string”
}
}
}{
“properties”: {
“Full name”: {
“type”: “string”
}
}
}

23. Stage 1: Scalar types
{
“properties”: {
“First name”: {
“type”: “string”
}
“Surname”: {
“type”: “string”
}
}
}
{
“properties”: {
“First name”: {
“$ref”: “http://apis.guru/types/name#”
}
“Surname”: {
“$ref”: “http://apis.guru/types/surname#”
}
}
}

24. Stage 2: Complex types
{
“properties”: {
“First name”: {
“$ref”: “http://apis.guru/types/name#”
},
“Surname”: {
“$ref”: “http://apis.guru/types/surname#”
}
}
}
{
“$ref”: “http://apis.guru/types/fullname/15#”
}

25. Stage 3: type converters
function (data) {
return {
“Full name”: data[“First name”] + data[“Surname”]
};
}
{
“First name”: “John”
“Surname”: “Smith”
}
{
“Full name”: “John Smith”
}
