Tool strategy

What this tool gives you

Generate or transform OpenAI SDK snippets to unlimitedcodex base URL, keys, and scopes. The tool is useful before checkout because it helps buyers make one specific OpenAI-compatible API access decision without sharing private secrets.

Best fit

Implementation prep when the buyer needs a usable config, snippet, payload, scope plan, or receiver scaffold.

Output

A copyable starter artifact the buyer can adapt to the delivered base URL, API key, and model IDs.

Next step

Apply the generated artifact, verify it with the relevant docs, then request setup delivery through a paid package.

Input boundary

Use only non-secret planning inputs. Do not paste raw API keys, bearer tokens, full auth headers, private logs, customer data, or billing screenshots. Generated snippets should use placeholders for BASE_URL, API_KEY, model IDs, webhook secrets, and environment variables.

Result use cases

Produce starter configuration, request, webhook, scope, or migration artifacts.
Use placeholders that can be replaced with the delivered base URL, API key, and model IDs.
Give implementation teams a concrete next step without exposing private credentials.

Output

// Use delivered ucx_test_... key in UCX_API_KEY
const response = await fetch("https://unlimitedcodex.com/v1/chat/completions", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.UCX_API_KEY}`,
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
  "model": "gpt-5.5",
  "messages": [
    {
      "role": "user",
      "content": "Validate this request shape before production cutover."
    }
  ]
})
});

if (!response.ok) {
  const error = await response.json();
  throw new Error(error.error?.message ?? "Request failed");
}

const result = await response.json();
console.log(result);

Migration checklist

Swap base URL to unlimitedcodex /v1 (or NEXT_PUBLIC_API_BASE_URL).
Keep OpenAI request shapes for chat, embeddings, and images.
Replace API keys with delivered ucx_live_ or ucx_test_ credentials.
Assign least-privilege scopes: chat:write, embeddings:write, images:write, usage:read.
Store keys server-side only — never in browser bundles or mobile apps.
Handle stream: true as unsupported (501 streaming_not_enabled).
Parse x-unlimitedcodex-quota-state on successful responses.
Branch 429 handling: rate_limit_exceeded vs quota_exceeded codes.
Review healthy → warning → urgent → blocked thresholds before launch.
Use separate keys for development, staging, and production.
