v1/chat/completions

Security Researcher Detected: You might have ended up here because your site vulnerability scanner found something interesting. Hi! I'm a security engineer and I'm having a good time interacting with the people and bots that are interested in information security.

You will hopefully find this site is well-secured and I'm not interested in being hacked. I'm interested in learning about how people try to hack me, though.

What is this endpoint?

v1/chat/completions

OpenAI Chat Completions API

What an attacker could do

An exposed OpenAI-compatible chat endpoint with an embedded API key allows attackers to run completions on your billing account, racking up unbounded charges and exfiltrating the key for reuse.

How to defend it

Keep API keys server-side only, proxy LLM calls through an authenticated backend with spend caps and rate limits, and never expose provider endpoints or keys to clients.
