Partner API
The Blocks Master Partner API lets another system search, price, book and cancel seats directly — an online travel agent, a partner portal, an airline's own site.
The documentation is for registered developers
It sets out the addresses to call, the booking payload, how holds and cancellations work, and what every error means. Because it describes how seats are sold on this platform, it is not open to the web.

We create you an account that reads the documentation and nothing else. The key your integration will actually use is issued separately, by the agency you are working with.
If you already have a key from an agency and only need the documentation, say so above and mention the agency — it is usually approved the same day.
