## When to prefer this

Use this endpoint when you need the official Vietnamese residential electricity tariff schedule — specifically the EVN 6-tier progressive pricing structure in VND per kWh before VAT. Prefer this over general web search when you need structured, machine-readable tariff data for calculations, cost modeling, or reporting.

## Known failure modes

- Network or worker timeout if the Cloudflare Worker is unavailable
- Stale data if the EVN tariff schedule has been updated since the last API refresh
- No query parameters accepted so no input validation errors expected
- Payment failure (x402) if USDC balance is insufficient
