# economics: benchmarks
a driver, and a population or a buyer profile to the benchmarks that apply, each with its interval, population, period, source and what its rights allow
[figure: The caller sends BenchmarksInput to /v1/economics/benchmarks. The platform returns a card whose body is [Benchmark].]
POST/v1/economics/benchmarks
Si.economics.benchmarks. The call needs the tenant rung under a token with the read grant, and it is served by either, by the size bound.
The route takes [BenchmarksInput](/concepts/benchmarksinput) and returns a card whose body is [Benchmark](/concepts/benchmark).
## Request body
The request body is [BenchmarksInput](/concepts/benchmarksinput).
| field | type | required | note |
|---|---|---|---|
| `driver` | [KindOfMeasure](/concepts/kindofmeasure) | yes | |
| `kind_of_buyer` | `text` | no | |
## Response
The route returns a card whose body is [Benchmark](/concepts/benchmark). Every card ends with a foot that states the basis of each number, the scope of the call, and the time when the facts were true.
## Headers
| header | required | meaning |
|---|---|---|
| `Scale-Scope` | yes | the scope the call runs in: tenant/, then /brand/, then /strategy/ |
| `Scale-As-True-On` | no | the date the facts must have been true on; defaults to now |
| `Scale-As-Known-On` | no | the date the facts must have been known on; defaults to now |
| `Scale-Key` | no | for a change, the key made from the input; a repeat under the same key returns the unit held and writes nothing |
A caller needs the tenant rung and a token with the read grant. The platform or the desktop app serves this route.
## Example
The example sends the smallest body that BenchmarksInput allows. The build validates it against the schema of BenchmarksInput.
Example
```sh
curl -X POST https://api.scaleintelligence.co/v1/economics/benchmarks \
-H "Scale-Key: $SCALE_KEY" -H "Scale-Scope: tenant/" \
-H "content-type: application/json" \
-d '{ "driver": "…" }'
```
```typescript
import { client } from "@scale/sdk";
const answer = await client.economics.benchmarks({
"driver": "…"
});
// answer.body is a [Benchmark]. answer.foot holds the basis, the scope and the time.
```
```python
import requests
answer = requests.post("https://api.scaleintelligence.co/v1/economics/benchmarks",
headers={"Scale-Key": KEY, "Scale-Scope": "tenant/"},
json={
"driver": "…"
}).json()
```
```rust
let answer: Card = client.post("https://api.scaleintelligence.co/v1/economics/benchmarks")
.header("Scale-Key", key).header("Scale-Scope", "tenant/")
.json(&BenchmarksInput { /* the fields of the page */ }).send().await?.json().await?;
```
