The Zeretis REST API gives you programmatic access to the full solver engine. Send an expression, get back an exact symbolic result and step-by-step JSON. No approximations, no stochastic behaviour — deterministic every time.
The API exposes the full Zeretis solver engine. Any problem type supported in the web interface is also available via API — with JSON input and output.
Linear, quadratic, polynomial, and systems of equations. Returns all solutions symbolically.
Derivatives, integrals, limits, and series — exact symbolic results, not numerical approximations.
First and second order ODEs with initial conditions, solved symbolically where a closed form exists.
Matrix operations, determinants, eigenvalues, row reduction — all returned exactly.
Every response includes a structured steps array — perfect for building educational tools or audit trails.
Simple bearer token authentication. Keys scoped per project. Usage tracked per key in your dashboard.
One primary endpoint covers all problem types. The mode parameter selects the solver engine.
A minimum monthly charge covers your first 10,000 calls. Beyond that you pay per call. No setup fees, no contracts.
