The layer between you and the model

Zero-latency pass-through to your provider. MSGF evaluates optimizations in the background and records projected savings — switch to enforcement mode when the ROI is credible.

1. Start a free trial — we mint your shadow-mode key. The 7-day clock starts on your first call (unused keys expire in 14 days).
2. Point OpenAI or Anthropic SDK baseURL at MSGF with x-msgf-mode: shadow.
3. Watch the proof ledger on your trial dashboard; get the email report when the window ends, then start 3-day Individual Pro full access.

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.OPENAI_API_KEY,
  baseURL: "https://elphiesgatedai.elphiesyntax.com/api/v1",
  defaultHeaders: {
    "x-msgf-mode": "shadow",
    "x-msgf-key": process.env.MSGF_LIVE_KEY!,
  },
});

import Anthropic from "@anthropic-ai/sdk";

const client = new Anthropic({
  apiKey: process.env.ANTHROPIC_API_KEY,
  // SDK appends /v1/messages — use /api (not /api/v1) as baseURL.
  baseURL: "https://elphiesgatedai.elphiesyntax.com/api",
  defaultHeaders: {
    "x-msgf-mode": "shadow",
    "x-msgf-key": process.env.MSGF_LIVE_KEY!,
