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.

Enables AI coding assistants and agents (Cursor, Claude Code, Windsurf) to access 19 native MCP tools and 400+ deterministic sub-30ms edge APIs—web-to-markdown, TokenSlimmer (-70% LLM cost cutter), prompt security shield, SEPA IBAN VoP, and EU DORA/AI Act compliance—via https://topaigateway.com

One endpoint in front of 950+ data APIs — SEO and AI visibility, finance, social, web search, sales and agent mail. tools/list returns five meta tools, not 580, so the catalogue never lands in a context window. Most clients can point straight at https://mcp.aisa.one/mcp; this package is the stdio bridge for the ones that only spawn a local command. OAuth, nothing to paste.
