Access of LLaMA-2-7b-chat-hf Model

I was trying to connect
$url = ‘/static-proxy?url=https%3A%2F%2Fapi-inference.huggingface.co%2Fmodels%2Fmeta-llama%2FLLaMA-2-7b-chat-hf%3C%2Fa%3E%E2%80%99%3Cbr%3E with PHP code using API key

but it gives
[error] => Model requires a Pro subscription; check out
Hugging Face – Pricing to learn more. Make sure to include your HF token in your query.

Please suggest any solution
