How to use OMA — 5 minutes, no jargon

OMA is one account for 21 AI models from many providers, paid your way. You do not need to be a developer or a crypto person to start. This is the whole site, in order. Developers: the API docs are your fast lane.

1. 01Try it free — no account needed

   Open the chat playground and send a message. Guests get 20 free messages a day across the three OMA-AI website-chat models, and 100 a day once you sign in. No credit card, nothing to install. The free set currently includes DeepSeek V4 Flash, MiniMax M2.7, and GLM-5.3 Flash.
2. 02Sign in with email or wallet

   Head to login. Choose email magic link (simplest — we email you a secure sign-in link, no password to remember) or connect wallet if you already use web3 apps. Signing in increases your free chat allowance and lets you create API keys and fund credits for paid models. Conversations are saved in this browser.
3. 03Create an API key

   In your dashboard, click "Create Key". It will look like oma_sk_.... Copy it and treat it like a password. You use this one single key to talk to any of the models OMA supports. You can easily revoke it later if you need to.
4. 04Add a little credit

   Go to Buy credits to see the available funding methods and deposit limits. Use USDC on Base or card checkout when available. Credits never expire while your account is active; how far they go depends on the model and the length of each request and response.
   
   Autonomous Agent option: If you are writing software agents, you can use our x402 settlement flow to verify and settle USDC into credits, then spend with an API key.
5. 05Make your first API call

   In an app, library, or script that supports OpenAI-compatible chat completions, set the base URL to https://www.oma-ai.com/api/v1, use your new API key, and choose an available model from our catalog. Check its capabilities before using tools or image inputs. Try the examples below, or jump to the developer quickstart.

curl https://www.oma-ai.com/api/v1/chat/completions \
	-H "Authorization: Bearer $OMA_KEY" \
	-H "Content-Type: application/json" \
	-d '{
		"model": "deepseek-v4-flash-0731-openbroker",
		"messages": [{"role": "user", "content": "Say hello in one short sentence"}],
		"max_tokens": 64
	}'
