I will integrate an API into your existing app or software
Leo S
About this gig
Connect one documented API to your existing app or software.
Basic covers ONE API, ONE agreed operation or data flow, and ONE existing project. Examples include fetching data into a screen, sending a form to an API, or calling an AI API and displaying its result.
Please contact me before ordering with your platform/framework, source structure, API documentation, sanitized request/response examples, and acceptance criteria. I will review compatibility and confirm the exact scope first.
You receive:
- The agreed API integration in your existing project
- Basic input validation and API error handling
- Modified source code and setup/run instructions
- One revision within the agreed scope
AI API integration is optional and must fit the confirmed scope. Full authentication/OAuth systems, payments, multiple providers, blockchain contracts, complete apps, deployment, and ongoing maintenance require separate scope and pricing.
You supply the API account/access and pay API and hosting fees. Configure credentials in your own environment; do not send secret keys or passwords in messages. The $35 Basic package covers the agreed integration only, not a complete software system.

I develop Android, iOS, web, backend, HarmonyOS, desktop and automation software. I can work in any programming language, with feasibility confirmed before ordering. I work solo using AI-assisted development, managing requirements, implementation, testing and handoff. My projects include an AI documentation tool, an Excel review workflow and a JLPT Japanese learning app. I also consider scoped blockchain requests after reviewing the requirements and code. We agree the platform, deliverables, acceptance criteria and price before starting.

FAQ
What does the Basic package cover?
One documented API, one agreed operation or data flow, and one existing project. We confirm the request, response, expected behavior, and acceptance criteria before you order. Additional APIs or operations need separate scope.
Can you integrate an AI API?
Yes, I can assess one documented AI API flow in an existing project. You provide the provider account and pay usage fees. Model training, a complete AI platform, or multiple providers are outside Basic.
Are login, OAuth, payments, or blockchain contracts included?
No. Basic uses existing API access configured in your environment. Building full authentication/OAuth systems, payment flows, blockchain contracts, or complete apps needs separate scope and pricing. Deployment is not included.
What do I receive and what does a revision cover?
Modified source code, setup/run instructions, and the agreed integration. One revision adjusts that integration to its acceptance criteria. New operations or providers are scope changes. API and hosting fees are yours.
