REST API Tax Code Fetch

I need a small, well-structured REST call that receives basic product details and a U.S. delivery address, then returns the correct sales-tax code in JSON. The third-party tax provider’s documentation and keys are already available; the job is to create the wrapper endpoint (or lightweight micro-service) that talks to that provider, forwards the request parameters, parses the response, and hands my application only the tax code we need. Key points • Data handled: product details supplied in the request body or query. • Action required: fetch the appropriate U.S. tax code from the existing tax API for the given destination. No create, update, or delete operations are needed. • Response format: strictly JSON. Deliverables 1. Clean, commented source (Node.js, Python, or another modern language you’re comfortable with). 2. A single endpoint specification (URI, verb, expected parameters, sample request/response). 3. Brief setup instructions plus a Postman collection or curl examples for quick testing. 4. Error handling that propagates provider issues back as clear JSON messages. The task is focused and should be quick for someone familiar with RESTful design and third-party API integration. The product being updated is IFS ERP software, using a workflow will be the ideal solution.
