P2Pay Market is a multi-rail Bitcoin P2P offer index. It aggregates public order books across peer-to-peer trading rails, normalizes pricing per fiat currency, and exposes a stable UI and API for spread and liquidity analysis.

This project is designed as an infrastructure layer for settlement-first payment flows. In the long run, the APIs published here will be consumed by p2pay-core to detect which market is the most liquid at any given moment and route payment intent toward that rail (best availability, best execution), instead of hard-coding a single provider.

If you are building payment systems that must work across countries, currencies, and inconsistent rails, this index helps you observe real market conditions — liquidity and spreads — and make routing decisions based on data rather than assumptions.
