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 — payable via invoice, card subscription, or native agent-to-agent payment, depending on how you're calling it.

MCP Tools (Built, Deployment In Progress)

• list_chains — List all available chains with row counts and date ranges
• query_ohlcv — Query OHLCV data by chain, symbol, timeframe, and date range
• get_stats — Aggregated statistics (min/max/avg price, volume, outlier count)
• DuckDB Engine — Direct Parquet querying, zero ETL, sub-second response

Roadmap

• Cloudflare Worker — Global edge deployment for low-latency access
• MCP Protocol — Native Claude/Cursor integration via MCP stdio
• Daily Updates — Automated incremental data refresh via GitHub Actions

Payment Options

Three ways to pay, matched to how you're using Data Factory — human subscriber, AI agent caller, or enterprise procurement.
