OnAPI vs Code Converter

OnAPI is a unified API gateway that lets developers call GPT, Claude, Gemini, Sora, Veo, and Google's Nano Banana image model through a single key. Swap your SDK base URL to OnAPI's endpoint, plug in an OnAPI key, and keep the rest of your integration unchanged.

The gateway speaks OpenAI-compatible and Anthropic-compatible protocols, so chat completions, Anthropic messages, streaming, function calling, and long-context requests work without a rewrite. OnAPI says new upstream models typically appear within 24 hours of release.

Two routing channels share the same account. The economy channel bills at a 1:1 rate multiplier for everyday volume. The official channel routes through paid keys tied directly to provider accounts at a 1:7.5 multiplier when you need a straighter path to upstream APIs.

OnAPI is aimed at builders shipping AI products, especially where direct provider billing is inconvenient. Top-ups run through Alipay, WeChat, USDT, and USDC. Account balance does not expire, and the site states there is no minimum spend.

The service runs on the open-source New API project (based on One API), which handles model aggregation and cross-format conversion between provider APIs.

Code Converter translates code snippets between programming languages in a browser editor. Pick a source language like JavaScript or Python, paste your code, choose a target language, and get converted output with syntax highlighting and copy-to-clipboard export.

Traditional porting means rewriting by hand or running brittle regex scripts. Code Converter uses AI models to map syntax across 20 plus languages including Rust, Go, Kotlin, and COBOL, and it stores conversion history when you log in so you can revisit past translations.

The free account allows up to 5 conversions per day across supported languages. PRO at $4.99 per month removes the daily cap, unlocks advanced model selection, and expands the context window, with a 7-day free trial on the pricing page.

Code Converter fits developers maintaining multi-language projects, students comparing language syntax, and teams migrating legacy code who need a quick first pass before manual review.
