Chile Subtel Telecom & Satellite Concessions Scraper

Scrapes all telecom and satellite concession filings from Chile's Subtel tramites portal (publico.subtel.gob.cl). Collects applicant details, concession type, submission and resolution dates, and official decree/resolution document links across all service categories and years.

What it does

The actor queries the Subtel (Subsecretaría de Telecomunicaciones) public portal for concession filing records. It sends authenticated partial-page requests to the portal's internal search API and parses the returned HTML table fragments.

For each concession record, the actor extracts:

• Applicant (company or individual) name and concession category
• Submission action label, tramite ID number, and date
• Resolution number, date, and official document link
• Decree number, date, and official document link
• Service type code (SI, SL, SP, or SR) and query year

Performance notes

• The portal enforces a one-year maximum search window per query.
• Each per-year, per-service-type query takes approximately 30–40 seconds to respond due to server-side database processing.
• With serviceType: ALL, the actor issues 4 requests per year (SI + SL + SP + SR). A 10-year full run issues 40 sequential requests, taking approximately 20–30 minutes.
• Concurrency is fixed at 1 to respect the portal's rate limits.
