Example Queries

// Get all terminals
const terminals = await client.callTool("get-terminals");

// Find routes from Chiclayo to Trujillo
const schedules = await client.callTool("get-departure-schedules", {
  departureTerminalId: "002",
  arrivalTerminalId: "001",
  date: "14/07/2025", // DD/MM/YYYY format

🛡️ API Integration

Supported Endpoints

• Terminals: GET /Home/GetSucursales
• Destinations: GET /Home/GetSucursalesDestino
• Schedules: POST /Home/GetItinerario (JSON)
• Tickets: POST /Consulta/PostConsulta (Form-encoded)
• FAQs: GET /Home/GetPreguntasFrecuentes

Data Handling

• JSON APIs: Direct deserialization for structured data
• HTML Scraping: Cheerio-based parsing for ticket information
• Date Formats: Peru timezone (America/Lima) with DD/MM/YYYY format
• Error Handling: Graceful degradation with JSON error responses

🧪 Development

Code Formatting

# Format code with Biome
bun run format

# Check formatting without writing
bunx biome check

Type Safety

• Strict TypeScript configuration with noUncheckedIndexedAccess
• Zod schemas for runtime validation
• Exact API field mapping in type definitions
