Free tier	A free API key after a reviewed application: 200 calls per minute (200m) at review Levels 1 to 4, up to 100 results per category per call, and a bulk download of search results to CSV (at most 1,000,000 records) in the Trove account. unit requests; metered on request-count; Most applications are answered within a week; The quota can be raised on request, subject to approval.
Price	none stated
Limits	request-rate 200 API calls per minute (200m) as the standard quota source per-object-cap 100 results per category per call; bulk download results limited to 1,000,000 records and 10 downloads at a time source write-gated (binding) a key is issued after a staff review of an application form; harvesting full text or AI use needs an approved exemption source
Binding	write-gated No call works without a key, and the key comes from a reviewed application; 200 calls a minute is met only after that.
Identity	email A Trove account is needed first (its sign-up fields are unverified: the sign-up page renders by script); then an application form asking for the account username and contact details, the call rate needed, why and how the API will be used, and an agreement to the API terms. No card is mentioned.
Egress	not applicable: XML or JSON answers; bulk download files are CSV
Per-object cap	100 results per category per call (n, default 20)
Retention	bulk download files are deleted automatically seven days after they are created (7 days)
Interface	rest REST over HTTPS at api.trove.nla.gov.au/v3 (result search, work, newspaper, gazette, magazine titles, list, people) with an OpenAPI file; the key goes in the key parameter or a header; XML by default, JSON with encoding=json endpoint: https://api.trove.nla.gov.au/v3/result
Tooling	any HTTP client
Composes with	Metadata for books, images, maps, music, journals and digitised newspaper and gazette articles from Australian libraries; article full text is included with include=articletext for approved uses.
Reliability	A keyless call answered HTTP 401 No API key found in request; the Trove website pages, not the API host, sit behind an Anubis proof-of-work challenge that a plain page fetch stores as a challenge page; keys can be withdrawn at the Library's discretion.
Notes	Storage: retrieved metadata may be cached for up to 30 days for offline use or performance; otherwise each display makes a live call; bulk download CSV files last 7 days. Bulk path: Download results in a Trove account (CSV of metadata and an abstract, up to 1,000,000 records, one category at a time, 10 downloads at a time) or bulkHarvest=true through the API. This is the read API; the deposit question has its own record in storage.
Evidence note	documented Key process, review levels, quota, caps, bulk download and caching limit are read from first-party pages; a keyless call answered HTTP 401, and the key application is behind a sign-up, so whether an individual key is granted is unverified: behind a sign-up.
