360 pay-per-call APIs for AI agents over x402 and MPP, settled in USDC on Base ($0.001-$0.25 a call, no account or API key). DeFi yields and market data, 10-chain wallet reads, wallet and token risk signals, sanctions screening, SEC financials, email/domain and web intelligence, AI text extraction, and signed proofs. Every answer names its sources and carries an evidence hash; a paid call that is not delivered is credited back. Built and run by UnyKorn LLC.
Check before your agent installs, connects or pays. install_check: before installing an npm or PyPI package, a GitHub repo, a skill or an MCP server, it answers allow / hold / block (known malicious packages from OSV, typosquats of official MCP servers, names that do not exist, install scripts, maintainer changes). check_service: live status, real price and payTo vs the catalogue listing for any x402 endpoint or MCP server, OFAC and stablecoin-freeze screening, uptime, tool-set changes, on-chain payers, an open Trust Score. preflight_payment decides allow / hold / block right before an x402 payment is signed; payment_status prevents paying twice; dispute_evidence builds a signed evidence pack. Every answer is signed into a public transparency log. Free, no account. Claude Code plugin: alalanet-guard.
