How this service works
LLM cost scout: send your monthly OpenAI API spend in USD and get back the flat ChatGPT/Codex subscription tier that absorbs it through the ProxyLLM gateway, the exact new monthly total and savings, the live model catalog, and machine-readable signup steps an agent can complete autonomously (email OTP, no browser).
Output
Returns the recommended subscription plan name, plan cost in USD, ProxyLLM flat fee ($129), equivalent API capacity per month in USD, calculated monthly savings, new monthly total, a live catalog of available models at the gateway, and machine-readable signup steps (email OTP-based, no browser required) that an agent can execute autonomously.
Example use cases
Example prompt
“I'm spending about $420 a month on OpenAI API calls — can you check ProxyLLM's cost scout to see which subscription tier would cover that, how much I'd save, and walk me through the signup steps?”
