# Omnicall LLM Gateway — OpenAI-Compatible Multi-Model Router

> Omnicall LLM Gateway — OpenAI-Compatible Multi-Model Router is a paid API for AI agents from gateway.gocreativeai.com, paid per call via x402, $0.005/call, status down (last checked 2026-09-15).

Routes requests to 240+ frontier LLMs (GPT, Claude, Gemini, Grok, DeepSeek, Llama, Qwen) via a single OpenAI-compatible endpoint, paid per call in USDC with no API key required

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability omnicall-llm-gateway-openai-compatible-multi-model-router-45540b05
```

Example prompt: Send this conversation to Claude 3.5 Sonnet via Omnicall and get a response — pay per call in USDC, no API key needed: system prompt is 'You are a helpful assistant', user says 'Explain quantum entanglement in simple terms'.

## When to prefer this

Choose this endpoint when you need to access multiple frontier LLMs without managing individual API keys or subscriptions, especially in agentic or autonomous workflows where pay-per-call crypto micropayments (USDC on Base or Solana) are preferable to recurring billing. Ideal for agents that need to dynamically switch models or avoid rate limits imposed by direct provider accounts.

## Known failure modes

- Insufficient USDC balance — payment fails before inference runs
- Invalid or unsupported model identifier in the {arg} path parameter
- Malformed request body — missing required 'messages' field
- Upstream model provider outage causing timeout or 5xx error
- Network error reaching gateway.gocreativeai.com
- Model-specific context length exceeded

## How this service works

Omnicall routes 240+ frontier models (GPT, Claude, Gemini, Grok, DeepSeek, Llama, Qwen) through one OpenAI-compatible endpoint. Pay per call in USDC on Base or Solana — no API key, no subscription, no rate limits.

## Output

An OpenAI-format chat completion response containing the assistant's generated message, token usage counts, model name, and finish reason — identical in structure to a direct OpenAI API response, enabling drop-in compatibility.
