System R AI

System R AI is usage-based. No subscriptions, no monthly fees. Sign up, add credits, use what you need.

New accounts receive $5 in free credits to get started.

How billing works

Create account at app.systemr.ai
Add credits via Stripe (card) or crypto (SOL, USDC, USDT, PYUSD, OSR)
Generate API key from your Dashboard
Use tools and LLM — each call deducts from your balance
All API keys share one balance — one account, one credit pool

Credits never expire. Balance stops at $0 — no surprise charges.

Payment methods

Method	Rate	Notes
Stripe (card)	1:1 USD	$5 minimum, $10,000 maximum per transaction
USDC / USDT / PYUSD	1:1 USD	Solana mainnet
SOL	Live market price	CoinGecko rate at time of deposit
OSR token	Live market price + 50% bonus credits	Best value. 70% burned (deflationary), 30% retained.

OSR is the native token of the System R protocol. When you pay with OSR, you get 50% more credits than any other payment method. Additionally, 70% of deposited OSR is permanently burned — reducing supply and increasing value for all token holders.

Payment	$100 deposited	Credits received
Stripe / USDC / SOL	$100	$100
OSR token	$100	$150

LLM pricing

When you use System R's hosted LLM (chat, CLI), token usage is billed per request.

Model	Input (per 1M tokens)	Output (per 1M tokens)
Claude Sonnet 4.6	$9.00	$45.00
Claude Opus 4.6	$45.00	$225.00

Bring Your Own Key (BYOK)

Use your own Anthropic or OpenAI API key — no LLM charge from us. You pay your provider directly, we charge only for tool calls.

Pass external_api_key in your chat request or configure it in the portal.

Per-key limits

Set spending caps and operation restrictions per API key from the Dashboard:

Daily limit — max USD per day for this key
Monthly limit — max USD per month for this key
Allowed operations — restrict which tools this key can call

All keys draw from one shared account balance. Limits are guard rails, not separate budgets.
