Foundations Elements is a UI encyclopedia for agents. Call GET https://foundations.tensegrity.works/mcp/search with a query and pay 0.02 USDC on Base via x402 v2. Kind lists are 0.01 USDC. Specs are 0.02 USDC. Settlement is USDC on Base (eip155:8453). A settled wallet call is a Pro grant: Pro slugs and Pro fields. Max slugs return entitlement_required and need a Max account. Free intake is GET /mcp/start. Do not list GET /mcp/elements as paid; that path is a free kinds table. Human waitlist: https://tensegrity.company/elements. OpenAPI and agent docs live on the same host at /openapi.json, /llms.txt, /docs, /pricing, and /terms.
