# Dataprovider.com API

> Programmatic access to structured data on 250M+ domains worldwide: 200+ fields covering company, technology, hosting, traffic and ownership, with 3+ years of monthly history. Query the dataset with DPQL (Dataprovider Query Language) and look up, enrich, or aggregate records over a REST/JSON API.

Authentication:
Send a personal access token in the `X-API-Key: <token>` header, or an OAuth2 bearer token in the `Authorization: Bearer <token>` header. OAuth2 tokens are issued at `https://api.dataprovider.com/v2/auth/oauth2/token`. Accounts with MFA enabled must use the `X-API-Key` header.

Notes:
- Requests and responses are JSON. The default rate limit is 120 requests/minute.
- Each returned record is billed; requests that return no records are not billed.
