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.
Example use cases
Switch models mid-workflow dynamically
“I need you to try this prompt on three different models — GPT-4o, Claude 3.5 Sonnet, and Gemini 1.5 Pro — using Omnicall so I don't need separate API keys. Pay per call in USDC on Base. System prompt: 'You are a concise technical writer', user message: 'Summarize the key differences between REST and GraphQL'. Show me all three responses so I can pick the best one.”
Run DeepSeek without signing up
“Use Omnicall to send this to DeepSeek-R1 — no API key, just pay per call in USDC. System prompt: 'You are an expert mathematician', user message: 'Walk me through how to solve a system of three linear equations using matrix elimination'. I don't want to create a DeepSeek account.”
Autonomous agent picks best LLM
“My agent needs to route this coding question to whichever frontier model is best for code generation right now — use Omnicall to call Qwen or Llama through the OpenAI-compatible endpoint, paying in USDC on Solana. System prompt: 'You are a senior software engineer', user message: 'Write a Python function that detects duplicate entries in a list of dictionaries by comparing a specific key'.”
Technical details
Endpoint
GEThttps://gateway.gocreativeai.com/v1/ai/eco/%7Barg%7DWhen to prefer
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.
Side effects
- 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
