Limitations

• No street address: the open Catastro publishes province, canton and parish of the head office, not the street. This actor returns province, canton and parish.
• No size or workers, e-mail, phone or website.
• legal_form is inferred from the company name (the SRI file has no legal-form column); 43k rows are "no determinado".
• About 21% of company RUCs issued by the SRI do not pass the classic modulo-11 check digit test; they are real RUCs.

Pricing

Pay per event: company-result, US$0.003 per company row returned (1,000 = US$3). Set a maximum cost per run and the actor stops when it is reached (OUTPUT.stopped_by_budget). Full files and custom segments: https://latsouth.com/data/ecuador/.
