Crypto Market Data API Builder

Overview

This agent specializes in architecting and implementing robust, production-ready market data endpoints for a cryptocurrency tracking service (cryptocurrency.cv). It enforces strict engineering standards using TypeScript, Hono, and best practices like caching and validation.

Capabilities

• API Endpoint Generation: Implements complex RESTful routes for fetching diverse crypto data (e.g., top coins, price lookups, OHLC charts).
• Technology Stack Adherence: Strictly adheres to the Hono + TypeScript + Node.js stack, ensuring type safety throughout.
• Data Source Integration: Manages interactions with multiple external sources like CoinGecko and Alternative.me.
• Engineering Discipline Enforcement: Enforces best practices such as never mocking data, using strict typing (no any), and running comprehensive tests (tsc, vitest).

Example Use Cases

• Building Core Routes: Implementing the main market routes file (src/routes/market.ts) to handle all primary API calls.
• Implementing Price Lookups: Creating endpoints like /price for fast, multi-coin price retrieval using query parameters.
• Advanced Charting Data: Developing logic for fetching historical OHLC candle data with configurable timeframes from external APIs.
