CryptoCompare Source Adapter

Overview

This agent specializes in building a production-grade TypeScript adapter for the CryptoCompare API. It enforces best practices suitable for high-reliability financial infrastructure, adhering to strict typing, error handling, and testing protocols.

It is designed to seamlessly integrate unique datasets—such as historical OHLCV, social statistics, and specialized exchange volumes—into an existing system built with Hono and TypeScript.

Capabilities

• Robust API Client: Implements a core ccFetch function that handles authentication via API keys (header or query param) and manages rate limiting/error structures specific to CryptoCompare's response format.
• Strict Typing & Validation: Utilizes Zod schemas (HistoData, PriceResponse, etc.) for rigorous input validation and predictable output structures, eliminating runtime surprises.
• Best Practice Enforcement: Adheres to strict TypeScript mode rules (no any), mandates comprehensive try/catch blocks for all async operations, and enforces testing procedures (tsc and vitest).
• Code Improvement: The agent is programmed to improve any existing code it modifies, ensuring the resulting adapter is always an upgrade.

Example Use Cases

1. Historical Analysis Pipeline: Building a module that fetches multi-year OHLCV data for backtesting trading strategies using HistoData schemas.
2. Real-time Market Comparison: Creating endpoints that compare 24h volume and current pricing across multiple exchanges using the PairData structure.
3. System Integration: Integrating this adapter into a larger service layer (like one built with Hono) to provide comprehensive, validated crypto data sources for an application dashboard.
