● degraded javascript-typescript

Non-custodial buyer SDK for x402 + MCP. Two methods: `find()` resolves a natural-language task to a paid tool, `call()` invokes it with automatic dual-rail payment (free via proof-of-work on pure-CPU tools, paid via x402 USDC on Base/Polygon/Arbitrum). Built-in caching, idempotent retries (`Idempotency-Key`), and Bazaar-shape 402 challenge handling. Works against any Agent402-compatible server.
