 ### Sender Chain Pattern
 
@@ -41,44 +39,48 @@ Each sender adds specific functionality (authentication, retries, headers, etc.)
 
 - **ClientBuilder**: Fluent API for configuring and building API-specific clients. Accepts either `StaticCredentials` (server-side: auth-id + auth-token) or `SharedCredentials` (client-side: embedded key).
 
-- **Lookup classes**: Each API has a `Lookup` that holds both input parameters and results after the API call. Located in `src/<api_name>/Lookup.js`.
+- **Lookup classes**: Each API has a `Lookup` that holds both input parameters and results after the API call. Located in `src/<api_name>/Lookup.ts`.
 
 - **Batch**: Container for up to 100 lookups. Single lookups use GET requests; batches with 2+ lookups use POST.

 ### API Modules
 
 Each API follows the same structure in `src/<api_name>/`:
-- `Lookup.js` - Input/output container
-- `Client.js` - Request/response handling
-- `Candidate.js`, `Result.js`, or `Suggestion.js` - Response data structures
+
+- `Lookup.ts` - Input/output container
+- `Client.ts` - Request/response handling
+- `Candidate.ts`, `Result.ts`, or `Suggestion.ts` - Response data structures
 
 Supported APIs: `us_street`, `us_zipcode`, `us_autocomplete_pro`, `us_extract`, `us_enrichment`, `us_reverse_geo`, `international_street`, `international_address_autocomplete`, `international_postal_code`
 
 ### Credentials
 
 Three credential types, each implementing a `sign(request)` method used by `SigningSender`:
-- **StaticCredentials** (TS) - Server-side: adds `auth-id` + `auth-token` query params
-- **SharedCredentials** (TS) - Client-side/browser: adds embedded `key` param + `Referer` header. Cannot be used with POST (batch) requests.
-- **BasicAuthCredentials** (TS) - Adds HTTP Basic Auth `Authorization` header

 Tests use Mocha + Chai (`expect` style). Test files are prefixed with `test_` and mirror the source structure under `tests/`.

 - `MockSender` - Captures the request for inspection
 - `MockSenderWithResponse` - Returns a fixed payload/error
 - `MockSenderWithStatusCodesAndHeaders` - Iterates through status codes (useful for retry tests)
 
 ## Code Style
 
 - Uses Prettier: tabs, double quotes, 100 char line width, trailing commas
-- Mixed JS/TS: Business logic (clients, lookups, results) in JS; infrastructure (credentials, senders, types) in TS
+- All source and test files are TypeScript with ES module syntax (`import`/`export`)
+- Import paths use `.js` extensions (TypeScript resolves `.js` to `.ts`)
