I Got Tired of Rewriting AI API Wrappers, So I Built a Gateway

Description and use

Developers building side projects often have to write separate wrappers for each AI provider, manage multiple keys, and deal with confusing billing. Apiarium consolidates all services into a single API gateway with one key, credit‑based billing, and a unified error format, simplifying development.

Problem

Developers building side projects repeatedly write separate wrappers for each AI provider, manage multiple API keys, and face confusing billing across providers.

Outcome

Developers can now use a single API key to access multiple AI services with predictable, credit‑based billing and consistent error handling, eliminating the need to maintain separate wrappers.

Workflow

• Create an Apiarium account and obtain an API key
• Add the key to your .env file as APIARIUM_KEY
• Use the /llm endpoint with desired model, e.g. "gpt-4o-mini" or "claude-haiku"
• Use the /image, /tts, or /transcribe endpoints similarly
• Monitor credit usage via the Apiarium dashboard
• Add new providers by implementing a single adapter without changing the API contract
