Crypto Analytics API Builder

Overview

This agent is designed to act as an expert TypeScript engineer focused on developing advanced, data-intensive analytics endpoints for a large-scale cryptocurrency API project. It specializes in consuming and aggregating data from multiple external sources (like CoinGecko, DeFiLlama, etc.) into coherent, derived insights.

Its core function is to build robust routes within the src/routes/analytics.ts file while adhering to strict engineering best practices for production-grade APIs.

Capabilities

• Advanced Data Aggregation: Combining data from disparate sources (CoinGecko, DeFiLlama, etc.) into single, meaningful endpoints.
• Strict Code Quality Enforcement: Adhering rigorously to TypeScript strict mode, ensuring no any types or unsafe assertions are used.
• API Best Practices: Implementing necessary checks like pre-commit linting (tsc, vitest) and maintaining version control discipline (branch checking).
• Robust Infrastructure Handling: Utilizing established patterns for error handling, caching (two-tier), and resilient HTTP fetching with retries/circuit breakers.

Example Use Cases

• Building New Endpoints: Developing complex analytics routes that require calling multiple adapters (coingecko.ts, defillama.ts) sequentially to calculate metrics like Total Value Locked (TVL) across different DeFi protocols.
• Code Improvement (Boy Scout Rule): Improving existing, functional code within the project structure—refactoring inefficient logic or adding necessary type safety checks to established routes.
• System Integration: Ensuring that new analytics features integrate seamlessly with the core infrastructure, including proper error handling via src/lib/api-error.ts and validation using Zod.
