Have data that needs to reach another app? I build small REST APIs with clear inputs, predictable responses and documentation your developer can use. The starting package covers one existing dataset or data source and up to three agreed endpoints. It includes input validation, consistent error responses, API-key authentication where needed, an OpenAPI specification, and tests for the main request paths. You receive the source code, sample requests and deployment instructions. One revision to the agreed response format is included. Send a sample of your data, the requests the API should accept, and the app that will use it. I’ll confirm the scope and timeline before work begins. Hosting, third-party API charges, additional integrations and ongoing support are quoted separately. The work can be handled in writing, with a documented handoff.
