About Plaid

Plaid is a financial data network that lets developers connect their applications to users' bank accounts. People link an account through a secure flow, and the app can then retrieve account and routing details, balances and transaction data through Plaid's API. Fintech companies use it to build products without integrating with each bank separately.

The vendor groups its offering into bank payments, credit scoring and underwriting based on real-time financial behavior, fraud protection, instant onboarding, and personal financial management. It says its network covers thousands of financial institutions across about 20 countries and describes its infrastructure as a base for AI-driven financial products.

Plaid is a hosted commercial API. Developers get documentation, API keys for testing and code samples, and the company publishes a pricing page and offers conversations with its sales team. It cannot be self-hosted.
