openrouter is the standard choice here . they aggregate basically everything (gpt4 , claude 3.5 , llama etc) and take crypto via coinbase commerce . api is openai-compatible so easy to swap in existing scripts .
if u need truly uncensored stuff tho (nsfw / blackhat gen) , public aggregators still filter heavy prompts sometimes . for that u better rent a gpu pod on vast.ai or runpod (both take crypto) and spin up a local endpoint with vllm . bit more setup but zero filters and cheaper at scale .
