2s.io SDK
Client SDK + MCP server for 2s.io — the (most) everything API. One pay-per-call API giving AI agents ground-truth data across hundreds of endpoints, paid per call in USDC on Base or Solana via x402.
This repo ships SDKs for every major agent-development language plus an MCP server for any MCP-aware host:

No accounts. No API keys. No credit cards. Buyers sign an EIP-3009 USDC authorization (Base) or an SPL USDC transfer (Solana) on-the-fly, the facilitator verifies + settles in ~2 seconds on mainnet, and the API returns typed data. Prices start at $0.001/call.
