We require a computer algebra system that is capable of solving math equations, along with steps. The system should be capable of solving most high school and university topics excluding applied mathematics.
The system should be an API service type that
will be installed in linux servers and accept HTTP requests and return results in MathML and/or other formats.
is on other server with reasonable pay per request billing
The system should be robust and highly scalable.
There are some similar system out there but they all have their drawbacks:
Sage - No RESTful API, does not show steps.
Wolfram Alpha - Proprietary, Unrealistic costs that no revenue model in existence could cover ($60 for 1000 calls)
Of course it is unrealistic to create such system from scrach, hence we are looking for modification to existing system or there may be some software with exact features that we overlooked. In the end you might just suggest the right software for us to try and you will get paid!
Please describe your proposed system to achieve our requirement in detail through PM, or your bid will be ignored.
