Basics
The Wappalyzer APIs provide programmatic access to technographic data on websites, either in real-time or prefetched.
- The APIs conform to REST principles
- The JSON data format is used for responses and POST requests
- All resources require authentication
- Requests are rate-limited and metered
- Endpoints are HTTPS only
API calls deduct credits from your balance. Credits are included in plans and can also be purchased directly. To determine the number of credits spent per request, refer to the pricing page.
Wappalyzer uses API keys to provide authorized access to its APIs. Sign up to create an API key.
| Request header | Value |
|---|---|
x-api-key | Your API key |
The APIs return HTTP status codes in addition to JSON-based responses.
| HTTP code | Description |
|---|---|
200 | The request was completed successfully |
400 | There was an error with the request |
403 | Authorisation failure (incorrect API key, invalid method or resource or insufficient credits) |
429 | Rate limit exceeded |
2xx code. A
4xx code indicates a problem with the request. A
5xx code means a server-side error occurred.
Every response includes a header with the credit spend and remaining balance.
| Header | Description |
|---|---|
wappalyzer-credits-spent | The number of credits deducted |
wappalyzer-credits-remaining | Your credit balance |
Alternatively, you can get your remaining credit balance by calling a separate endpoint:
GET https://api.wappalyzer.com/credits/v2/balance/
curl -H "x-api-key: <your api key>" "https://api.wappalyzer.com/credits/v2/balance/"
{ "credits": 100000 }
