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

> Omnicall LLM Gateway — OpenAI-Compatible Multi-Model Chat is a paid API for AI agents from gateway.gocreativeai.com, paid per call via x402, $0.02/call, status down (last checked 2026-09-15).

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

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-chat-89f84f55 -d '<json body>'
```

Example prompt: Use Omnicall to send a chat completion request to Claude — ask it to summarize the following paragraph in three bullet points: 'The global economy is shifting rapidly as AI adoption accelerates across industries, creating both new opportunities and significant displacement risks for workers worldwide.' Pay per call in USDC, no API key needed.

## When to prefer this

Prefer this endpoint when an AI agent needs to call frontier LLMs without managing multiple API keys or subscriptions, especially in crypto-native or autonomous agent contexts where per-call USDC payment on Base or Solana is desirable. Ideal for agents that need to dynamically switch between GPT, Claude, Gemini, Grok, DeepSeek, Llama, or Qwen through a single OpenAI-compatible interface.

## Known failure modes

- Insufficient USDC balance — payment fails before request is processed
- Invalid or unsupported model name — returns 400 or model-not-found error
- Malformed request body — missing required messages field returns 422
- Model provider outage — upstream model temporarily unavailable, returns 503
- Rate limit or timeout on upstream model provider side
- Network error reaching gateway.gocreativeai.com

## 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

Returns an OpenAI-compatible chat completion JSON object containing the generated text from the selected frontier model, including message content, model name, token usage, and finish reason.
