A cost estimation tool for the tax code lookup API. Fixed tiers — enter the number of requests per month to see the total cost.
Parameters
Each
GET /tax-code call = 1 request. No encryption; billed by regressive volume tiers.Tiers (fixed)
| Up to request # | Unit price |
|---|---|
| 100 | 4.000đ |
| 500 | 2.000đ |
| 1.000 | 1.000đ |
| ∞ (beyond) | 500đ |
Result
Total / month (100 requests)400.000đ
Average effective unit price: 4.000đ / request
| Tier | Requests | Unit price | Amount |
|---|---|---|---|
| 1 – 100 | 100 | 4.000đ | 400.000đ |
| 1.001 – ∞ | 0 | 500đ | 0đ |
How it is calculated
Cost = Σ (tier unit price × number of requests in the tier) — regressive/volume-based tiered pricing.
| Tier (up to request #) | Unit price / request |
|---|---|
| 100 | 8.000đ |
| 500 | 4.000đ |
| 1.000 | 2.000đ |
| > 1.000 (excess) | 1.000đ |
Example of 700 requests/month: 100×8.000 + 400×4.000 + 200×2.000 = 800.000 + 1.600.000 + 400.000 = 2.800.000đ.
Shared metering
Requests are counted by endpoint using the same counter as the input invoice lookup API — see reconciliation at Usage reconciliation (requests.byEndpoint).
