SAS-CBSD Interface is one of 6 APIs that [Federated Wireless](https://apis.io/providers/federated-wireless/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include CBRS, SAS, and Spectrum.

The regulated Spectrum Access System to CBSD protocol interface Federated Wireless operates as an FCC-certified SAS administrator. The protocol — registration, spectrum inquiry, grant, heartbeat, relinquishment and deregistration — is defined by Wireless Innovation Forum WINNF-TS-0016 and FCC 47 CFR Part 96, not by Federated Wireless; the company implements it and markets a "Deregistration API" from it. The interface is mutual-TLS and restricted to registered CBSD operators, so it is not reachable from the public internet and no contract is published.
