The Australian Communications and Media Authority (ACMA) is the Commonwealth regulator for telecommunications, radiocommunications, broadcasting and online content in Australia. It issues carrier licences and apparatus and spectrum licences, maintains the Register of Radiocommunications Licences, administers the Australian telephone numbering plan through the Numbering System, operates the Do Not Call Register, and polices the Telecommunications Consumer Protections and scam-call rules that bind Telstra, Optus, TPG and every other Australian carrier. Its API posture is that of a regulator: two real programmatic surfaces, both attached to a statutory register rather than to a platform. The ACMA Spectrum Licensing API is fully public and anonymous — a WCF service at api.acma.gov.au exposing 22 REST operations (XML and JSON projections of eleven web methods) plus a SOAP endpoint and a live WSDL, letting anyone query licences, licensees, transmitter sites, device registrations, antennas, access areas and the 400 MHz band register, capped at 2,000 records per query. The Do Not Call Register's Real Time Access washing service is a live, publicly-retrievable ColdFusion SOAP WSDL whose three operations require a paid industry subscription, alongside an SFTP automated washing channel at sftp.donotcall.gov.au. ACMA also runs an Azure API Management developer portal at developer.acma.gov.au that is entirely behind a sign-in wall. Public register and licence bulk data is published as daily file downloads and on data.gov.au rather than as a queryable API. ACMA is a regulator, not an operator, so it sits outside the CAMARA and GSMA Open Gateway commitment layer entirely; no CAMARA reference was found anywhere in its public surface.
ACMA publishes 1 API on the APIs.io network: Spectrum Licensing API. Tagged areas include Telecommunications, Australia, Regulator, Spectrum, and Broadcasting.
ACMA’s developer surface includes developer portal, documentation, API reference, getting-started guide, support, pricing, signup flow, and 20 more developer resources.

description: '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.'

name: Do Not Call Register Real Time Access (RTA) Washing Service
description: 'The Do Not Call Register is operated by the ACMA under the Do Not Call Register Act 2006. Telemarketers and
fax marketers must check ("wash") their contact lists against the register before calling. ACMA documents four submission
channels for washing, two of which are programmatic — "Automated Washing Service (AWS/SFTP)" and "Real Time Access (RTA/SOAP)"
— alongside manual Quick Wash keying and website file upload. The RTA channel is a ColdFusion SOAP web service whose WSDL
is publicly retrievable at https://www.donotcall.gov.au/dncrtelem/rtw/washing.cfc?wsdl and which exposes three operations:
GetAccountBalance, WashNumbers and GetWashResult. Calling it requires an industry account and a paid washing subscription
(type D or above); the credentials are an Account/Telemarketer ID and passphrase passed in the SOAP body, with an optional
wash-only sub-account ID. TLS 1.2 or above is mandatory. ACMA recommends up to 200 numbers per call, a hard ceiling of
500 numbers per payload, and fewer than 5 million numbers per month through this channel. Wash results are returned per
number as Y (on the register), N (not on the register) or I (invalid phone number). The AWS/SFTP channel is a batch alternative
at sftp.donotcall.gov.au using SSH key authentication with upload/download/archive folders.'
