Keeping usage and formats tied to the receiving system
This worksheet calculates the displayed relationship from the supplied quantities. Its label and period conventions determine how the amount should be interpreted. A technical estimate needs the billable unit or output format the receiving system expects. Requests, tokens, storage and transfer can have separate rates. A text transformation should preserve meaningful characters rather than promise validation it does not perform.
Scope of this operation
The figure includes only the listed inputs. It does not add unlisted tax, overhead, provider charges or conversion losses. Negative results can represent a shortfall or the signed difference between options. The example output for api cost assumption sheet is shown below so the supplied source can be checked against the actual format. It is not evidence that the operation has run against your own file or account.
How it works
Monthly API cost = [Monthly requests] × [Rate per request] + [Other billable units] × [Extra unit rate]
Inputs
| Field | Example | Definition |
|---|---|---|
| Provider / API | Provide provider / api as the source record shown by the example. The tool uses the supplied text and does not retrieve missing facts from an external account. | |
| Monthly requests | 100000 | Use the source quantity represented by monthly requests. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Rate per request | 0.001 | Use the source quantity represented by rate per request. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Other billable units | 0 | Use the source quantity represented by other billable units. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Extra unit rate | 0 | Use the source quantity represented by extra unit rate. Keep the counted population fixed and avoid mixing a unit value with a period total. |
