Pay for LLM APIs with crypto.
Stablecoin top-ups. No bank card required.
Router One accepts USDT and USDC on six networks. Top up, get a wallet balance in USD, and call any of 25+ LLM models through an OpenAI-compatible endpoint — built for developers whose local card flow is unreliable but whose stablecoin wallet already works.

Supported networks
USDT and USDC on six chains. Pick the network that matches your wallet — Router One credits your balance in USD regardless of which chain you used.
| Network | Tokens | Typical confirmation | Gas economics |
|---|---|---|---|
| Tron (TRC-20) | USDT, USDC | ~30s | Cheapest — pick for small top-ups |
| BSC (BEP-20) | USDT, USDC | ~5s | Very cheap |
| Polygon | USDT, USDC | ~5s | Very cheap |
| Base | USDC | ~3s | Cheap |
| Arbitrum | USDT, USDC | ~1s | Cheap |
| Ethereum (ERC-20) | USDT, USDC | ~30s–3min | Most expensive — use only for top-ups over $500 |
Billing scope and compliance
- Account records
- For standard self-serve accounts: email (for receipts and password reset) and the payment-chain address you send from (publicly visible by nature of any on-chain transaction).
- Treasury workflow
- Crypto top-ups are built for teams that prefer stablecoin treasury workflows or non-card billing. Enterprise contracts, invoicing, abuse reviews, or legal requirements may require additional information.
- Compliance boundary
- A crypto top-up is not permission to bypass laws, sanctions, export controls, or upstream model-provider terms. You are responsible for using the service lawfully in your jurisdiction.
How the wallet works
- Top up
- From your dashboard, pick a network. Scan the QR or paste the deposit address. Send USDT or USDC from your wallet. Tron and BSC are cheapest on gas; Ethereum mainnet is slowest and most expensive.
- Settle
- Tron, BSC, Polygon, Base, Arbitrum settle in seconds. Ethereum mainnet can take a few minutes. Once the network confirms, your balance updates.
- Wallet currency
- Accepted stablecoin deposits are credited into a USD wallet balance at receipt time according to the checkout terms shown before payment. After credit, your balance is plain USD.
- Spend
- Every API call deducts the per-model rate from your USD wallet at posted rates on /models. The same rate applies regardless of whether you topped up in RMB, USD, or stablecoin.
Who actually uses this
- Developer in Istanbul
- Local bank cards are unreliable for USD API credits. Tops up Router One with USDT on BSC and calls GPT-5.5 + Claude Opus 4.7 through one endpoint.
- Developer in Buenos Aires
- Peso volatility makes prepaid USD budgeting painful. Pays Router One in USDC pay-as-you-go from a Polygon wallet and runs market-data analysis jobs on Claude Sonnet 4.6.
- Developer in Karachi
- Cross-border card approvals are inconsistent for developer tools. Uses USDT on Tron via a local OTC desk and ships a customer support bot on Gemini 3.1 Pro.
Minimums and fees
- Minimum top-up
- Crypto top-ups start at the equivalent of 50 USDT/USDC. WeChat Pay, Alipay, and Stripe top-ups start at $5 USD equivalent.
- Network fee
- Network gas is paid by you to the chain. Any Router One or channel-side fees, if applicable, are shown before checkout. Pick Tron or BSC for small top-ups to keep gas low.
- Router One markup
- API calls deduct from your USD wallet at the posted model rates. Pricing methodology and the revenue model are documented on /pricing-methodology.
Why Router One specifically
- vs OpenAI / Anthropic direct
- Direct provider billing may require a supported card or USD billing setup. Stablecoin top-ups are not part of their standard self-serve API billing flows.
- vs OpenRouter
- OpenRouter supports cards, crypto, bank transfers, and enterprise invoicing. Router One's distinction is China-friendly routing plus WeChat Pay, Alipay, and six-chain USDT/USDC top-ups in the same gateway.
- vs informal API resellers
- Cheap relay stations can obscure the actual model or provider serving a call. Router One publishes per-request traces showing the upstream provider and rate that served each call — see /routing-methodology and /security.
FAQ
- Do I need a US credit card to use Router One?
- No. Top up with USDT or USDC on any of six chains (Tron, BSC, Ethereum, Polygon, Base, Arbitrum). The resulting USD wallet works against every model on /models.
- Who is crypto billing for?
- Crypto billing is for global teams and developers that prefer stablecoin treasury workflows or non-card billing. Enterprise contracts, invoicing, abuse reviews, or legal requirements may require additional information.
- Which chain is cheapest for a $50 top-up?
- Tron (TRC-20) and BSC (BEP-20) have the cheapest gas — typically well under $1 per transaction. Ethereum mainnet only makes sense for top-ups over $500 where the gas is amortized.
- What happens if I send the wrong token or wrong chain?
- Funds sent on a chain Router One does not list, or in a token not supported on that chain, may be unrecoverable. Always match the token and network shown on the deposit page exactly. This is a universal property of any on-chain deposit, not a Router One restriction.
- Can I withdraw my wallet balance back to crypto?
- Wallet balance is non-refundable and cannot be withdrawn. Top up only what you plan to consume through API usage. Wallet balance never expires.
- Is my deposit address shared with anyone?
- Your deposit address is unique to your account. The transaction itself is on-chain and publicly visible by nature of how blockchains work; Router One does not share or sell wallet associations.
