Mahshar is an API marketplace paid per call in USDC. Sellers list endpoints and set a per-call price; buyers discover APIs and pay via x402 nanopayments settled through Circle Gateway, with each 402 response advertising both Arc Testnet and Base mainnet. A Next.js proxy layer (src/lib/proxy.ts and the /api/proxy routes) injects seller credentials server-side, keeps real endpoints hidden from buyers, and records on-chain call receipts through src/lib/memo.ts. Groq-powered routes handle listing review with live endpoint tests (/api/ai/score) and natural-language API matching (/api/ai/match), while /api/agent/discover serves a machine-readable catalog for autonomous buyers. Seller credentials rest under AES-256-GCM encryption in src/lib/crypto.ts, backed by the Supabase schema in supabase/schema.sql.
