Application programming interface scoring, ranking and selection
A method for ranking a set of APIs for multiple software applications executing on respective servers, including initializing, by a first computer, respective ranking scores for the APIs, and receiving, from a plurality of second computers, multiple API calls to the APIs in the set. For each given API call to a given API in the set received from a given second computer, a given server executing a given software application including the given API is identified, the given API call is forwarded to the identified server, a response to the given API call is received from the identified server, performance metrics with respect to the given API call and response are computed, and the ranking score for the given API are updated based on the computed performance metrics. The APIs can be provided to the second computers responsively to the ranking scores, as updated in response to the requests.

computing, based at least on the responses, respective performance metrics for the APIs; and
ranking the APIs based on the computed performance metrics; and
at a second time subsequent to the first time period:
receiving, in the computer, a request to execute the specific operation; and
executing the specific operation by automatically selecting, based on the rankings, a given API, and conveying an API call to the selected API.
2. The method according to claim 1 , wherein computing respective performance metrics for the APIs comprises computing respective performance metrics for the API calls, and wherein ranking the APIs in the set comprises ranking the API calls based on the computed performance metrics.
3. The method according to claim 1 , and comprising receiving, from the selected one or the servers, a response to the conveyed API call to the selected API.
4. The method according to claim 3 , wherein the computer comprises a first computer and wherein the instruction to execute the specific operation is received from a second computer, and comprising forwarding, by the first computer to the second computer, the received response to the API call to the selected API.
5. The method according to claim 3 , and comprising computing, based at least on the response to the API call to the selected API, updated respective performance metrics for the selected API, and re-ranking the APIs in the set based on the updated computed performance metrics.
6. An apparatus, comprising:
a memory; and
a processor configured:

to compute, based at least on the responses, respective performance metrics for the APIs, and
to rank, in the memory, the APIs based on the computed performance metrics; and
at a second time subsequent to the first time period:
to receive a request to execute the specific operation, and
to execute the specific operation by automatically selecting, based on the rankings, a given API, and conveying an API call to the selected API.
7. The apparatus according to claim 6 , wherein the processor is configured to compute respective performance metrics for the APIs by computing respective performance metrics for the API calls, and wherein the processor is configured to rank the APIs in the set by ranking the API calls based on the computed performance metrics.
