## Project Overview I need a developer to build an **AWS Lambda function (Python 3.14)** that programmatically retrieves vehicle inspection history (VTV) from the Buenos Aires Province system. The public page is: [https://vtv.gba.gob.ar/consultar-vtv](https://vtv.gba.gob.ar/consultar-vtv) The actual API endpoint being called is: [https://vtv-web-api.transporte.gba.gob.ar/api/historialvtvs/patente/Af839du](https://vtv-web-api.transporte.gba.gob.ar/api/historialvtvs/patente/Af839du) The API request requires a valid **Cloudflare Turnstile token** to be sent in the header: ``` X-Turnstile-Token: <token> ``` ## Objective Create a production-ready Lambda function that: * Accepts a vehicle plate as input (example: `Af839du`) * Obtains and solves the Cloudflare Turnstile challenge (using Anti-Captcha or similar) * Calls the protected API endpoint with the required headers * Returns structured JSON output * Is fully deployable on AWS Lambda (Linux x86_64 runtime) --- ## Required Headers (as observed) The request must replicate browser behavior, including headers such as: ``` sec-ch-ua-platform: "macOS" User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/145.0.0.0 Safari/537.36 sec-ch-ua: "Not:A-Brand";v="99", "Google Chrome";v="145", "Chromium";v="145" DNT: 1 Content-Type: application/json sec-ch-ua-mobile: ?0 Accept: */* Sec-Fetch-Site: same-site Sec-Fetch-Mode: cors Sec-Fetch-Dest: empty host: vtv-web-api.transporte.gba.gob.ar X-Turnstile-Token: <generated_token> ``` The Lambda must properly handle: * Session initialization * Cookies * Turnstile token generation * Proper header injection --- ## Deliverables 1. `lambda_function.py` (production-ready) 2. `requirements.txt` 3. Deployment-ready ZIP including dependencies 4. `build.sh` (Docker-based build for Lambda compatibility) 5. README with: * Environment variable setup * Deployment steps * Example test event * Troubleshooting notes --- ## Environment Variables The solution must use environment variables for: * `ANTICAPTCHA_API_KEY` * `TARGET_BASE_URL` * Optional proxy configuration (if IP consistency is required) --- ## Lambda Input Example ```json { "plate": "Af839du" } ``` --- ## Expected Output Structured JSON including: * timestamp * requestId * payload * metadata * result (raw API response) --- Budget: 25usd
