## Description
**Barikoi APIs** is the official TypeScript/JavaScript SDK for [Barikoi Location Services](https://barikoi.com). Built on auto-generated code from the official OpenAPI specification, it provides a modern, type-safe interface for accessing a wide range of location-based services including search, geocoding, reverse geocoding, routing, and more.
This SDK is optimized for modern web applications including React, Next.js, Vue.js, and vanilla JavaScript projects.
## Features
- **Auto-generated with @hey-api/openapi-ts** - Always synchronized with OpenAPI specification
- **100% TypeScript Inference** - Zero type imports required, full IntelliSense everywhere
- **Built-in Validation** - Automatic Zod schema validation with clear error messages
- **Runtime API Key Management** - Update API keys dynamically without reinitializing the client
- **Modern Async/await** - Promise-based API with configurable timeouts
- **Custom Error Classes** - ValidationError, BarikoiError, TimeoutError
- **Multiple Build Formats** - ESM, CommonJS, IIFE, UMD and TypeScript declarations
- **Tree-shakeable** - Import only what you need for optimal bundle size
- **CDN Ready** - Use directly in browsers via unpkg or jsDelivr

### Autocomplete
Search for places with autocomplete suggestions. Returns matching places with
addresses in `English` and `Bangla`, coordinates, and place details. Use for search
boxes, address forms, and location pickers.
```typescript
const result = await barikoi.autocomplete({
q: 'Dhaka',
bangla: true,
})
const places = result.data?.places || []
```
---
Type Definitions
```typescript
export type AutocompleteParams = {
/** Search query string (required)
* @minLength 1
*/
q: string
/** Include Bangla language fields
* @default true
*/
bangla?: boolean
}
export type AutocompleteSuccess = {

### Reverse Geocoding
Convert coordinates to human-readable addresses with administrative details (district, division, thana) in `English` and `Bangla`. Use for displaying user location, delivery
addresses, and location tagging.
**IMPORTANT:** ⚠️ Enabling all optional parameters triggers multiple API calls, consuming more credits. Request only essential parameters.
```typescript
const result = await barikoi.reverseGeocode({
latitude: 23.8103,
longitude: 90.4125,
district: true,
bangla: true,
})
const place = result.data?.place
