AlicenseAqualityAmaintenanceEnables AI agents to call paid APIs and settle HTTP 402 payment challenges with USDC on Base, without private keys ever being involved.7231 npmMIT- AlicenseNot gradedqualityAmaintenanceEnables AI agents to check their wallet address and USDC balance, preview the cost of an x402 call, and pay for API requests in USDC on Base without an account or API key. Spend caps, allow-lists and blocked contracts are enforced in code before anything is signed, so a prompt injection cannot bypass them.MIT
- AlicenseNot gradedqualityBmaintenanceEnables AI agents to make payments over x402-priced HTTP APIs using USDC on Monad testnet, with policy enforcement, budgets, and approval workflows, without exposing private keys.8AGPL 3.0
- AlicenseNot gradedqualityCmaintenanceEnables AI assistants to call pay-per-call x402 endpoints on Base mainnet using the caller's own USDC wallet, covering single and batch token risk checks, the latest BTC radar signal, project info, and a free health probe. Payments are EIP-3009 signed with a configurable per-call spending cap, and any quote with an unexpected payee, network, or asset is refused before payment.MIT
- AlicenseNot gradedqualityCmaintenanceEnables AI agents to make pay-per-call USDC payments on Base via x402 for headless page rendering, temporary file hosting, scheduled callbacks, and pump.fun launch and trend feeds.MIT
- AlicenseNot gradedqualityCmaintenanceEnables AI agents to autonomously pay for metered web APIs on a per-call basis, settling x402 v2 USDC micropayments via EIP-3009 authorization on Base Sepolia without human involvement. Spending is bounded by configurable per-call caps and host restrictions, and exposes tools to fetch paywalled URLs and inspect the agent wallet's address and balance.MIT

Scored across 4 tools
Each tool maps to a clearly distinct action: HTTP fetching, budget inspection, EVM transaction execution, and audit inspection. Although x402_fetch and x402_safe_tx both involve spending controls, their resources and outcomes are clearly separated.
All tools share the consistent x402_ prefix and use readable snake_case, but the verb pattern is slightly mixed: x402_fetch and x402_get_budget are verb-led, while x402_safe_tx and x402_audit_log are noun/adjective-led. The deviation is minor and still predictable.
Four tools is well-scoped for a focused firewall/payment-safety server. Each tool covers a distinct core capability without obvious padding or triviality.
The surface covers the main lifecycle: safe fetching, budget visibility, safe transaction execution, and audit review. Minor gaps exist around managing or updating spending caps and allowlists, but core firewall workflows are represented.
