Does anyone have an API that maintains a list of all model versions for a provider? I hand-update OpenAI into a JSON file that I use for cost reporting in my apps (and in an npm package called llm-primitives).

Here's the current version:

    const pricesPerMillion = {
        "o1-2024-12-17": { input: 15.00, output: 60.00 },
        "o1-mini-2024-09-12": { input: 1.10, output: 4.40 },
        "o3-mini-2025-01-31": { input: 1.10, output: 4.40 },
        "gpt-4.5-preview-2025-02-27": { input: 75.00, output: 150.00 },
        "gpt-4o": { input: 5.00, output: 15.00 },
        "gpt-4o-2024-08-06": { input: 2.50, output: 10.00 },
        "gpt-4o-2024-05-13": { input: 5.00, output: 15.00 },
        "gpt-4o-mini": { input: 0.15, output: 0.60 },
        "gpt-4o-mini-2024-07-18": { input: 0.15, output: 0.60 },
        "gpt-4-0613": { input: 30.00, output: 60.00 },
        "gpt-4-turbo-2024-04-09": { input: 10.00, output: 30.00 },
        "gpt-3.5-turbo": { input: 0.003, output: 0.006 },
        "gpt-4.1": { input: 2.00, output: 8.00 },
        "gpt-4.1-2025-04-14": { input: 2.00, output: 8.00 },
        "gpt-4.1-mini": { input: 0.40, output: 1.60 },
        "gpt-4.1-mini-2025-04-14": { input: 0.40, output: 1.60 },
        "gpt-4.1-nano": { input: 0.10, output: 0.40 },
        "gpt-4.1-nano-2025-04-14": { input: 0.10, output: 0.40 },
        "gpt-4o-audio-preview-2024-12-17": { input: 2.50, output: 10.00 },
        "gpt-4o-realtime-preview-2024-12-17": { input: 5.00, output: 20.00 },
        "gpt-4o-mini-audio-preview-2024-12-17": { input: 0.15, output: 0.60 },
        "gpt-4o-mini-realtime-preview-2024-12-17": { input: 0.60, output: 2.40 },
        "o1-pro-2025-03-19": { input: 150.00, output: 600.00 },
        "o3-pro-2025-06-10": { input: 20.00, output: 80.00 },
        "o3-2025-04-16": { input: 2.00, output: 8.00 },
        "o4-mini-2025-04-16": { input: 1.10, output: 4.40 },
        "codex-mini-latest": { input: 1.50, output: 6.00 },
        "gpt-4o-mini-search-preview-2025-03-11": { input: 0.15, output: 0.60 },
        "gpt-4o-search-preview-2025-03-11": { input: 2.50, output: 10.00 },
        "computer-use-preview-2025-03-11": { input: 3.00, output: 12.00 }
    };

I would love to replace this with an API call.
