OmniaKey — Claude, GPT, Gemini, and Grok for coding agents

OmniaKey is a coding-first LLM gateway. One API key gives your coding agent — Claude Code, Cursor, Codex, Cline, aider — access to curated Claude, GPT, Gemini, and Grok models from Anthropic, OpenAI, Google, and xAI. You pay per token against a prepaid balance, with no monthly fee and no plan tiers.

One key, three native protocols

OmniaKey speaks each vendor’s protocol on a single host — https://api.omniakey.com. Point your tool at the protocol it already uses; no SDK changes required.

Protocol	Base URL	Use it with
OpenAI-compatible	`https://api.omniakey.com/v1`	Codex, Cursor, Cline, aider, OpenAI SDKs
Anthropic-native	`https://api.omniakey.com`	Claude Code, Anthropic SDKs
Gemini-native	`https://api.omniakey.com/v1beta`	Google Gen AI SDKs

Claude, GPT, Gemini, and Grok ids are reachable over the OpenAI-compatible Chat Completions endpoint (/v1/chat/completions), so most tools need only that one base URL. Reach for a vendor’s native protocol when your tool already speaks it (Claude Code → Anthropic, Google Gen AI SDK → Gemini). See the API Reference for per-protocol curl and SDK examples plus the full protocol × vendor matrix.

The Anthropic SDK appends /v1/messages itself, so its base URL is the bare host. The OpenAI and Gemini SDKs use the /v1 and /v1beta suffixes above.

Quick example

Point Claude Code at OmniaKey with two environment variables:

export ANTHROPIC_BASE_URL="https://api.omniakey.com"
export ANTHROPIC_AUTH_TOKEN="your-omniakey-api-key"
claude

Or use any OpenAI-compatible SDK by changing the base URL:

from openai import OpenAI

client = OpenAI(
    api_key="your-omniakey-api-key",
    base_url="https://api.omniakey.com/v1",
)

response = client.chat.completions.create(
    model="claude-opus-4-8",
    messages=[{"role": "user", "content": "Refactor this function for readability."}],
)

print(response.choices[0].message.content)
