API Guardrails is a free compliance checker that scans your AI API usage against provider Terms of Service. Paste your code or config and instantly see if you are violating rate limits, data retention policies, or usage restrictions for OpenAI, Anthropic, Google, Groq, and more. Built for developers who ship fast but need to stay compliant.

Most AI prompts are full of filler. "In order to" is 4 tokens — "to" is 1. "Due to the fact that" is 6 tokens — "because" is 1. You're paying for words that add nothing. TokenShrink strips the fluff. Paste any prompt on the web, or npm install tokenshrink for your codebase. Every replacement is verified against GPT-4's tokenizer so it never increases your token count. 12-15% savings on typical system prompts. No AI calls. No API keys. No sign-up. Just cleaner prompts.
