Zephyr Data Factory

Overview

Zephyr Data Factory is the API layer for Zephyr's curated datasets. Instead of downloading static files, subscribe to programmatic access — always up-to-date, always consistent.

Built on Cloudflare Workers for global low-latency delivery, with built-in authentication, rate limiting, and usage-based billing via Polar.sh.

Planned Features

• REST API — Query OHLCV data by chain, symbol, timeframe, and date range
• Incremental Updates — Daily delta endpoints so you never re-download
• Multiple Formats — JSON, Parquet, CSV output options
• Usage Billing — Pay only for what you query, with monthly caps
• API Keys — Secure authentication with scoped access tokens
