Pricing

Solrouter is metered per API call. Prepay in USDC or $ROUTER from your Solana wallet — no subscription, no credit card, no email required.

Most AI platforms make you commit before you build: a monthly subscription, a credit card on file, an email to verify. Solrouter does none of that. You pay per API call from a balance you fund yourself, so you only ever spend what you use.

The setup is short. Connect a Solana wallet at solrouter.com/sdk, fund your balance with USDC or $ROUTER, generate an API key, and start building. Every product — the Privacy SDK, Agent Privacy API, MCP server, and chat app — draws from that same prepaid balance.

There are no hidden fees. You pay per call from your prepaid balance. When the balance reaches zero, calls stop — nothing is billed retroactively.

Payment methods

You can fund your balance two ways. Both cost the same per call; the difference is what each one means for you and for the token.

USDC

Pay with USDC from your Solana wallet. As a stablecoin pegged to the dollar, its value stays put — so you carry no price risk between top-ups. Top up at any time from solrouter.com/sdk.

$ROUTER

Pay with the native $ROUTER token at the same per-call price as USDC. Every fee you pay in $ROUTER feeds the buyback-and-burn model — see $ROUTER buyback and burn below.

x402 keyless payments

An autonomous agent often has no human around to sign up for an account or manage an API key. x402 solves that: it lets an agent pay for each call on its own, with no registration at all.

x402 is a standard for HTTP-native micropayments — payments built directly into the web request itself — settled in USDC on Solana mainnet and facilitated by Coinbase. Any x402-aware agent can discover the payment manifest and start paying immediately.

Discovery: /.well-known/x402 — the x402 paywall manifest listing available endpoints and pricing.
Endpoint: POST /api/v1/x402/chat/completions — Arcium-encrypted prompt in, encrypted response out.
Price: $0.005 per call, settled on-chain before the request is processed.
Best for: autonomous agents that self-fund their own inference costs without a human managing API keys.

Going keyless costs you no privacy. The x402 path runs the same end-to-end encrypted inference as the API-key path: your prompt is still encrypted with RescueCipher before it reaches Solrouter's backend.

Managing your balance

You can read your current balance straight from the SDK, so an agent or app can check funds before it spends and top up when it runs low.

const { balance, balanceFormatted } = await client.getBalance();
console.log(`Balance: ${balanceFormatted}`);

To add funds, visit solrouter.com/sdk and connect your Solana wallet. Deposit USDC or $ROUTER in any amount — there is no minimum.

$ROUTER buyback and burn

Here is what your fees do for the token. The model is deliberately simple and mechanical: no emissions, no staking curves, no tiered discount programs — just supply that tightens as the network is used.

100% of USDC revenue flows into buying back $ROUTER on the open market.
50% of each buyback is permanently burned, reducing total supply.
50% of $ROUTER fees paid directly are burned at the time of payment.

Every call you make — whether you pay in USDC or $ROUTER — tightens supply. See /docs/payments/tokenomics for the full token mechanics, supply schedule, and vesting details.
