A Rust CLI that acts as a payment layer for HTTP, wrapping tools like curl and AI agents (Claude, Codex, Goose) to automatically handle HTTP 402 payment challenges via x402 and MPP protocols using Solana stablecoins. It includes a built-in MCP server, a local wallet-approval flow, and a payment gateway server for API providers.

Use cases

• pay for paid APIs from the command line without accounts or API keys
• let AI agents make paid API calls with human wallet approval
• wrap curl or claude to handle HTTP 402 payment challenges automatically
• monetize an API with pay-per-request stablecoin payments
• discover and call metered paid API endpoints from an agent
• run a payment gateway in front of an existing API

When to choose

• you want agents or scripts to pay per-request for APIs using stablecoins on Solana
• you need x402 or MPP 402 challenge handling in CLI or agent workflows
• you want human-in-the-loop wallet approval for agent spending
• you are an API provider adding pay-per-use pricing without accounts

When to avoid

• you need payments on chains other than Solana or in fiat
• you prefer traditional API keys, subscriptions, or card-based billing
• you need a fully autonomous agent payment flow without local user authorization
• your stack requires a managed payment processor like Stripe
