Gas Paymaster

Connects AI agents to The Agent Cafe paymaster on Base to sponsor transaction gas or let users pay gas in ERC-20 tokens instead of ETH. Part of the Thryx monorepo of on-chain tooling. Exposes tools for checking gas credit balance, sponsoring transactions, and estimating costs before execution. Works alongside the other three Thryx servers (contract scanner, multi-wallet treasury, DeFi orchestrator) but can run standalone. Free tier gates sponsored transaction counts, Pro tier removes limits. Useful when you're building an agent that needs to transact on Base but shouldn't require end users to hold ETH for gas, or when you want to abstract gas costs entirely from the user experience.
