# paramount.x402.fi

This host serves agents that need to programmatically complete a one-time $100 Paramount+ subscription checkout using on-chain USDC payment on Solana mainnet. It is a narrow, transactional endpoint — not a subscription management platform — and is purpose-built for the x402 exact-price payment scheme. Agents must supply all required payment fields (asset, payTo, amount, scheme, network, feePayer) to execute the purchase.

## When to use this host

Use this host when an agent needs to complete a single $100 Paramount+ subscription purchase and can settle in USDC on Solana mainnet via the x402 exact-price scheme. Do not use it for partial payments, subscription renewals, billing management, or cancellations — those require a dedicated billing or subscription management API. Do not use it for purchasing any other digital goods or streaming services; route those to the appropriate storefront. If the agent requires a different payment amount, currency, or network, this host cannot accommodate that and an alternative payment endpoint must be used.
