I integrate a public or private REST API into your website or web app and deliver clean, tested, documented code.

Included: • One API integration with up to three endpoints • Authentication setup with client-provided test credentials • Data fetching, parsing, validation, error handling, and clear UI or JSON output • Source code in JavaScript or Python • Setup notes and one revision

Please send the API documentation, current code or tech stack, required endpoints, and expected output. I keep secrets out of public code and test the result before delivery.
