# HTTPayer MCP

> Use this tool when you need to access x402-gated APIs without directly handling blockchain payments, and instead utilize a central credit balance to simplify transactions. It solves problems related to payment complexity and data fetching from restricted endpoints, providing inputs such as API requests and outputs like usage balances and transaction costs. Ideal for use cases requiring seamless interaction with payment-gated services, abstracting away underlying blockchain intricacies.
