Connects to Simpson Strong-Tie's structural connector catalog (C-C-2024) with nine specialized tools for construction engineering lookups. You can search 400+ connector models, verify load capacities against ASD requirements, size holdowns for uplift, match hurricane ties to lateral loads, and get corrosion protection recommendations. It handles seismic design category classification per ASCE 7-22 and maps IBC/IRC code sections to products. Built as an agent-to-agent service using the x402 payment protocol with USDC on Base L2. Most queries cost $0.01 to $0.03 per call. Reach for this when you need programmatic access to structural connector specifications and code-compliant product selection without parsing PDFs or catalogs manually.
Agent-to-Agent MCP + REST Service — No Human UI
Complete Simpson Strong-Tie structural connector catalog (C-C-2024) exposed as a headless service. Agents call it, agents pay for it, agents get engineering answers.

x402 protocol — USDC on Base L2. Include X-Payment-Hash header with transaction hash after sending payment.
Internal Hive services: use X-API-Key header.
Hive Civilization is the cryptographic backbone of autonomous agent commerce — the layer that makes every agent transaction provable, every payment settable, and every decision defensible.
