# Partner API

[The Blockchain.com Pay](/pay/welcome-to-blockchain.com-pay.md) Partner API centres around three main features, Authentication, Eligibility and Quotes. An additional section on Rate Limits will help maintain a stable integration.

* [Authentication](/pay/api/partner-api/authentication.md) - associates requests to your account
* [Eligibility](/pay/api/partner-api/eligibility.md) - provides information on supported currencies, regions, and payment methods
* [Quotes](/pay/api/partner-api/quotes.md) - provides prices for crypto transactions
* [Orders](/pay/api/partner-api/orders.md) - get latest state of user orders
* [Rate Limits](/pay/api/partner-api/rate-limits.md) - defines operating parameters of API usage

The full API specification file is available for download, below.
