How reAPI works
reAPI is a model-name rewriting proxy. It sits between your client and your upstream AI provider, translating the model names your client sends into the model names your provider understands.
The problem it solves
Claude Desktop and the Claude for Office add-in validate model names against a claude-* pattern. They will only send requests for models named claude-something. If you want to use a different provider — DeepSeek, Qwen, or any Anthropic-compatible API — you can't just change the model name in the client. reAPI accepts the claude-* name your client sends and rewrites it to whatever upstream model you've configured.
The rewrite mechanic
Your client sends a request with model: claude-opus-4-5. reAPI looks up your mapping for that name, finds the upstream URL and model you configured, rewrites the model field, and forwards the request. The upstream responds; reAPI streams the response back to your client unchanged. Your client never knows the model name was rewritten.
Short codes as identity
There is no account, no username, no password. Your short code is your identity. It's an 8-character string issued when you create a code. It appears in your BYOK base URL and is used as the API key in Hosted mode. Save it — if you lose it, it can't be recovered.
Common questions
- Q.01
Does reAPI ever see my prompts or responses?
No. Request and response bodies are forwarded upstream and streamed back to your client. reAPI logs only metadata — model name, token counts, timestamps — and never persists prompt or response content.
- Q.02
Which clients work with reAPI?
Any client that speaks the Anthropic API protocol. Claude Desktop and the Claude for Office add-in are the two with screenshot-level setup guides. Any other Anthropic-compatible client works the same way.
- Q.03
Is the short code permanent?
The code itself doesn't expire, but your access depends on your mode. Your key mode requires an active subscription or PAYG enabled. Hosted mode requires a wallet balance. If neither condition is met, requests are rejected — but the code and your mappings are preserved. Top up or subscribe to resume.
