A tiny (~500 bytes) CrUX API wrapper supporting both record and history APIs, with TypeScript types, automatic retry on rate limits, and URL normalization. Current stable version: 4.1.0. Release cadence: irregular, with major versions for breaking changes (ESM conversion in v3, dropping effectiveConnectionType in v4). Key differentiators: isomorphic (browser + Node.js), returns null on 404, handles 429 with retries, and provides TypeScript definitions for API responses. Alternatives require manual fetch handling and lack type safety.
