What it does

Provides a curated, searchable list of 134+ free‑tier LLM API endpoints and keys from 40+ providers so founders can plug cheap or no‑cost AI models into their apps.

When to use it

•You need a quick, cost‑free LLM for a prototype and don’t want to sign up for a paid OpenAI plan.
•Your product must support multiple model vendors (e.g., Gemini, NVIDIA NIM, Groq) to avoid vendor lock‑in.
•You want to benchmark several free LLMs side‑by‑side before choosing a paid provider.

Ready-to-paste prompt

curl https://generativelanguage.googleapis.com/v1beta/models/gemini-pro:generateContent?key=$GEMINI_API_KEY \
  -H 'Content-Type: application/json' \
  -d '{"contents":[{"role":"user","parts":[{"text":"Write a 2‑sentence elevator pitch for an AI‑powered resume reviewer."}]}]}'

Heads up: Most “free” keys are rate‑limited and may expire after a few weeks; you must re‑register for a new key or switch providers when you hit the quota.
