Basics

Our APIs provide programmatic access to our comprehensive database of websites and companies, as well live analysis of websites and email addresses.

The APIs…

• Conform to REST principles
• Return JSON data
• Require authentication
• Are metered and rate-limited
• Are HTTPS only

API calls cost credits. Credits are included in selected plans. Additional credits can be purchased at any time.

API keys are used for authorized access. Sign up to create an API key.

Requests to your callback endpoint can optionally be signed to allow you to verify the request was made by us. To enable signing, create a signing secret.

To verify a request, create a SHA256 hash of the signing secret appended with the raw JSON request body. The request is valid if the hash matches the hash in the wappalyzer-signature header in the request.

sha256(secret + body) == signature

The APIs return HTTP status codes in addition to JSON-based responses.

Every successful response includes headers with the numbers of credits that were spent and your remaining balance.

Alternatively, you can get your remaining credit balance by calling a separate endpoint:

GET https://api.wappalyzer.com/v2/credits/balance/

Request

curl -H "x-api-key: <your api key>" "https://api.wappalyzer.com/v2/credits/balance/"

Response

{
  "credits": 100000
}
