100% Free Public API · Fair Use Policy

Terms of Use & Public API Conditions

Clear rules for using our free Dominican RNC, Cédula, and NCF/e-CF platform responsibly — built to keep public DGII data open to everyone without daily paywalls.

Public access without paywalls or daily quotas

Unlike platforms that lock Dominican taxpayer lookups behind paid API subscriptions or strict daily request caps, UrbanStock POS provides this web portal and JSON REST API 100% free of charge for businesses, accountants, POS systems, and developers — because public official DGII records should be fast and accessible to everyone.

Permitted Integrations vs. Prohibited Abuse

Allowed (Encouraged)

  • Real-time checkout lookups for POS, ERP, e-commerce stores, and invoicing software (including Form 606/607/e-CF workflows).
  • Batch validation up to 50 tax IDs per call via POST /api/v1/rnc/batch and normal CORS browser usage.
  • Automated tests and demos using reserved sandbox IDs (000000000, 00000000000, EMPRESA DE PRUEBA).

Strictly Prohibited

  • Mass A-to-Z registry scraping, brute-force enumeration, or bypassing rate limits / 25-result search caps to harvest databases.
  • Denial-of-service traffic, oversized payloads (>32 KB), or abusive bot concurrency that degrades service for other users.
  • Misrepresenting UrbanStock RNC responses as official DGII tax certificates or government endorsements.

To keep the free tier fast without daily paywalls, sliding-window per-minute limits apply (120/min RNC lookup, 40/min search, 20/min batch) with an automatic 5-minute cooldown (HTTP 429) upon repeated limit abuse.
