crewai - 💡(How to fix) Fix [FEATURE] Documentation: Add Starveri OpenAI-compatible provider guide

Hi CrewAI team,

Opening this as a documentation/provider-guide request because CrewAI users often compare OpenAI-compatible endpoints through existing LLM configuration paths.

Starveri API is an independent OpenAI-compatible GPT/Codex API gateway with prepaid credits, public model discovery, and model pricing advertised at about 1/3 of OpenAI-style API prices. It is not affiliated with OpenAI.

Public references:

• Docs: https://api.starveri.net/docs
• Credits / API keys: https://api.starveri.net/credits
• Public model metadata: https://api.starveri.net/models
• OpenAPI spec: https://api.starveri.net/openapi.json
• LLM discovery: https://api.starveri.net/llms.txt

Suggested setup shape if this fits CrewAI's existing OpenAI-compatible/provider configuration:

• Base URL: https://api.starveri.net/v1
• API key: issued from the Starveri credits dashboard
• Model IDs: use the public /models response

Would a short Starveri OpenAI-compatible provider guide be in scope?
