ACMA Spectrum Licensing API

The ACMA Spectrum Licensing API is an application programming interface which allows members of the public to query the ACMA's spectrum licensing data — the Register of Radiocommunications Licences — so it can be used by external developers to build mobile or web applications. It is completely open: no API key, no account, no registration and no authentication of any kind. Both a REST endpoint (consumable from a browser) and a SOAP endpoint are exposed over the same eleven web methods, each published in an XML and a JSON projection, for 22 operations in total: licence search, client (licensee) search, site search, site-by-location proximity search, device registration search, assignment search by postcode/frequency/date range, antenna register search, access area lookup, licence category list, licences-in-category list and the 400 MHz band spectrum licence register search. A single query returns at most 2,000 records — a deliberate cap to discourage bulk extraction through the API — and callers page past it with the offset parameter; the complete dataset is published separately as a daily zip download. ACMA documents the service in a published guide (Spectrum Licensing API v1.0, 17 June 2016) and serves a live WSDL plus XML Schemas from the endpoint itself. Two operations, SpectrumLicenceImageSearch and ExtractSpectrumLicensingPDF, are marked Deprecated in the guide and are absent from the live WSDL.

Where this information came from

This is an independent, third-party profile of ACMA Spectrum Licensing API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
