Hi I can develop you a Python script to automate data query from SRI website, for user provided list of RUC/ID numbers, and extract required data into JSON format. I will provide you README instructions to setup and run the program on your end. I'm available to start right away. Abdul H.

@techplusintl

Hi there, I understand that you need to automate the querying of the SRI website to retrieve specific information based on RUC or cédula numbers. This includes fields such as the taxpayer's status, business name, ghost taxpayer indicator, and main economic activity. I will develop a script that allows you to manually execute queries with a list of RUCs, ensuring that the output is formatted as JSON for each identification consulted. I will implement random waits and user-agent rotation to prevent blocking, adhering to your acceptance criteria. My approach focuses on writing clear, well-commented code without unnecessary dependencies, ensuring reliability and ease of use. I will also provide a brief README with installation and usage instructions. I prioritize effective communication and quality in my work, and I am confident that I can deliver this project within the estimated timeframe. Looking forward to the opportunity to work together. Best regards, Burhan Ahmad from TechPlus

@intelliresponse

With over 13 years of experience, I bring a wealth of expertise in Python web automation and scraping that would be extremely valuable for your project. Having developed tailored solutions for similar data extraction projects, I understand the criticality of timely and accurately retrieving information from governmental portals while bypassing potential blockages or captchas. Adhering to your core requirements, I'll create a script that can be manually executed with your list of RUCs as input. I believe what differentiates me is not just my ability to efficiently get the work done, but the quality and clarity of my deliverables. Your JSON requirement will be met without adding any unnecessary dependencies. Moreover, I am familiar with employing techniques like random waits and user-agent rotation to maintain reasonable query time. Since you require the script rather than a service, you can expect clean, commented code emphasizing efficiency and robustness delivered within the agreed timeframe. My experienc

Your SRI scraper will fail if you don't handle their CAPTCHA and session token rotation correctly. I've seen three freelancers deliver broken scripts for this exact portal because they ignored the anti-bot middleware that kicks in after 5 requests. Before I architect the solution, I need clarity on two things: 1. Does your RUC list contain 50 identifications or 5,000? The approach changes completely - small batches can run sequentially with random delays, but high volume needs proxy rotation and distributed requests. 2. Are you running this from Ecuador or internationally? SRI blocks non-EC IPs aggressively, which means you'll need residential proxies or a VPS in Quito to avoid instant 403 errors. Here's the technical approach: - PYTHON + SELENIUM: Headless Chrome with undetected-chromedriver to bypass Cloudflare fingerprinting and handle dynamic JavaScript rendering that blocks basic requests library calls. - CAPTCHA HANDLING: Integrate 2Captcha API for automated solving when SRI triggers challenges (happens randomly every 10-15 requests). Falls back to manual intervention if budget is tight. - SESSION MANAGEMENT: Rotate user-agents and maintain cookie persistence across requests to mimic human behavior. Implements exponential backoff when rate limits hit. - JSON OUTPUT: Structured schema with error logging - if a RUC returns "No encontrado" or times out, it logs the failure reason instead of breaking the entire batch. - RETRY LOGIC: Automatic retry with 3-5 second delays for network failures or temporary blocks, then marks the RUC as "requires manual review" after 3 attempts. I've scraped 4 Latin American government portals including SUNAT (Peru) and AFIP (Argentina) where anti-bot measures are similar. The key difference with SRI is their session tokens expire every 8 minutes, so the script needs to refresh the base URL periodically. I don't take projects where the client expects 100% success rate on government scrapers - there will always be 2-5% that need manual verification due to portal downtime or CAPTCHA failures. Let's discuss your volume and timeline so I can give you a realistic delivery estimate instead of promising something that breaks in production.

Hola, He revisado los detalles de su proyecto y definitivamente puedo ayudarle con la automatización de la consulta en la página del SRI. Tengo más de 10 años de experiencia en desarrollo de scripts para scraping web, utilizando herramientas efectivas en Python, PHP y C#. Mi enfoque es crear un código claro y eficiente que cumpla con sus requisitos y evite bloqueos mediante técnicas de espera aleatoria y alternancia de user-agents. Primero, crearé un script que reciba una lista de RUCs y devuelva un archivo JSON con los campos que ha mencionado. Además, incluiré un README con instrucciones detalladas para la instalación y uso del script. Aquí está mi portafolio: https://www.freelancer.in/u/ixorawebmob Estoy muy interesado en su proyecto y me encantaría discutir más detalles. ¿Me podría indicar si tiene alguna preferencia en cuanto a la tecnología utilizada para este script, o si le gustaría revisar algo más específico? ¿Tiene alguna preferencia en cuanto a la tecnología utilizada para este script, o le gustaría revisar algo más específico? ¡Espero su respuesta!

Soy Leo Sarmiento, desarrollador Full‑Stack con 10 años de experiencia en automatización. Propongo desarrollar un script en Python con Playwright que consulte una lista de RUCs, extraiga Estado, Razón social, fantasma y actividad económica, y genere JSON por cada identificación; el script incluirá esperas aleatorias, rotación de user‑agent y manejo de captcha opcional, junto con un README detallado para su ejecución local. ¿Podemos coordinar una breve llamada para precisar el volumen de consultas y confirmar el enfoque?

@ricardopalma2304

Soy especialista en extracción de datos. Si revisas mi perfil, verás reseñas de scraping ya realizados con éxito, lo que garantiza un enfoque probado en entornos con bloqueos complejos. Enfoque Técnico Tecnología: Usaré Python con Playwright. Es más rápido que Selenium y maneja mejor el renderizado dinámico del SRI para asegurar que el "Indicador Fantasma" se capture tras cargar la página. Evasión de Bloqueos: Implementaré rotación de User-Agents y esperas aleatorias (comportamiento humano) para minimizar el riesgo de baneo de IP. Manejo de Captcha: Dejaré el script listo para resolución manual asistida o integración con APIs (2Captcha/Anticaptcha) si requieres automatización total. Entregables Script Python: Modular, recibe lista de RUCs y genera un JSON individual por consulta. Campos: Estado, Razón Social, Contribuyente Fantasma y Actividad Principal. README: Guía de instalación y uso en 3 pasos. Plazo: 3-4 días (incluye pruebas de estrés).
