Includes a free, no-wallet preview of price and coverage plus hard per-call and per-session spend caps, while misses and ambiguous matches cost nothing.

Enables static security audit of Solidity smart contracts by analyzing source code or deployed bytecode for vulnerabilities, providing risk scores and detailed findings.

Quick-scan a smart contract for rug, honeypot, or centralization risk before sending funds. It combines verified source, live on-chain state, and heuristic Solidity analysis to return a SAFE/CAUTION/HIGH-RISK verdict.

Universal x402 buyer agent — discover, pay for, and call any x402 paid API endpoint from Claude Desktop, Cursor, or Claude Code with automatic USDC payment via AgentCash.

Enables an AI assistant to read token bonding curves, quote trades with fee breakdowns, monitor graduation progress, and optionally launch, buy, sell, or rescue tokens on Arc via arcnow.io.

MCP server that scores the behavioral risk of a wallet on Base before sending it money. Provides a risk score, verdict, and explainable flags based on USDC payment history.

Hashlock Markets — sealed-bid intent-based crypto trading via MCP for AI agents. Atomic cross-chain settlement (Ethereum, Bitcoin, Sui) using HTLC. Six MCP tools for RFQ price discovery without information leakage and HTLC settlement without escrow or bridges. Canonical npm: @hashlock-tech/mcp.

Pay-per-call data and tools for AI agents over x402, by UnyKorn. 360 endpoints: DeFi and market data, multi-chain wallet reads, wallet and token risk signals, SEC filings, web and domain intel, and AI text tools. Settled per call in USDC on Base ($0.001-$0.25). No API keys or subscriptions; unpaid calls return the exact quote first.
