Use the API Playground to try any Contractag endpoint without leaving this site. The form above each endpoint builds a real request to https://api.contractag.dev so you can see how the API responds with your data.
The embedded runner currently executes cURL requests. Use it for quick checks, then adapt the sample code below if you prefer Python, JavaScript, or .NET in your application.

​
Try it

1

Choose an endpoint

Open any entry under Endpoints to load the Playground with the correct method and path.
2

Add your token

Select Set token, paste your API key, and we’ll send requests with Authorization: Bearer <token>.
3

Send the request

Fill in the required fields, hit Send, and review the live response in the results panel.

​
Sample code

Use these snippets as a starting point when you wire the API into your stack.

​
Bash (cURL)

curl -X POST https://api.contractag.dev/... \
  -H "x-api-key: $CONTRACTAG_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{ "key": "value" }'

​
Python

import requests

response = requests.post(
    "https://api.contractag.dev/...",
    headers={
        "x-api-key": "YOUR_TOKEN",
        "Content-Type": "application/json",
    },
    json={"key": "value"},
)
response.raise_for_status()
print(response.json())

​
JavaScript

await fetch("https://api.contractag.dev/...", {
  method: "POST",
  headers: {
    "x-api-key": "YOUR_TOKEN",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({ key: "value" }),
});

​
C# (.NET)

using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;

// inside an async method
using var client = new HttpClient();
client.DefaultRequestHeaders.Add("x-api-key", "YOUR_TOKEN");

var payload = new StringContent("{\"key\":\"value\"}", Encoding.UTF8, "application/json");
var response = await client.PostAsync("https://api.contractag.dev/...", payload);
response.EnsureSuccessStatusCode();
var body = await response.Content.ReadAsStringAsync();
Console.WriteLine(body);
