About
Hermes is an unofficial REST API and MCP server that tracks Ryanair flight prices over time, keeping every fare observation instead of only today's price, so it can show price history, price drops, and route data that Ryanair's own site does not expose. It covers over 5,200 routes across 224 airports and offers a free guest tier with 90 days of price history and no signup, plus six MCP tools for AI assistants to query fares directly.
Why it made the leaderboard
Exposes Ryanair fare history that Ryanair's own API doesn't provide, via a REST API and an MCP server, letting an AI assistant directly answer whether a fare is a good price.
