XAFare

XAFare is a modular software framework for calculating fares in transportation and logistics applications. It provides a configurable fare engine, rate cards, and pricing rules to support ride-hailing services, taxi fleets, delivery operations, and transit integrations.

The architecture centers on a pluggable fare engine that translates trip attributes (distance, duration, location, vehicle type) into a price. Key components include a rate-card system for base fares and multipliers, a rule engine for discounts, surcharges, taxes, tolls, and currency handling, and a data layer that ingests maps, traffic data, and external pricing sources. An API layer enables integration with mobile apps, dispatch systems, and partner platforms.

Pricing capabilities include dynamic and time-based pricing, demand-based surges, zone-based pricing, promotions, loyalty discounts, and tax and toll calculation. The framework emphasizes multi-tenant deployment, localization support for currencies and units, and testability through sandbox environments and simulated trips.

Deployment and interoperability: XAFare can be used as an embedded library within client applications or deployed as a standalone microservice. It exposes REST and gRPC interfaces and supports common data formats, authentication methods, and auditing. The project emphasizes clear pricing rules, versioning of rate cards, and extensible integration points for regional regulations.

Impact and reception: Since its release, XAFare has been adopted by several mobility and logistics platforms seeking a standardized pricing foundation. It is maintained by an open-source community and documented with examples and reference implementations. See also: dynamic pricing, rate card, toll calculation.
