Verified steps
Generate an audio fingerprint client-side using Chromaprint (via fpcalc or a Chromaprint binding) to get a duration and fingerprint string for a track
Register your application at acoustid.org to obtain a `client` API key (do not reuse the public example key beyond initial testing, since it expires quickly)
For lookups, call `https://api.acoustid.org/v2/lookup` with `client`, `duration`, and `fingerprint`, plus an optional `meta` parameter (e.g. recordings, releasegroups, compress) to control what MusicBrainz metadata is returned
For submissions, call `https://api.acoustid.org/v2/submit` with your `client` key and a per-user `user` API key (obtained by each user signing into acoustid.org — never hard-code a shared user key), along with `duration`/`fingerprint` and optional metadata like `mbid`, `track`, `artist`, `album`
Submissions are processed asynchronously — poll `https://api.acoustid.org/v2/submission_status` with the returned submission `id` to confirm when a fingerprint has been imported
Respect the stated rate limit of no more than 3 requests per second and the non-commercial usage restriction of the free web service
Known gotchas
The `client` key identifies your application, while the `user` key identifies the person contributing a fingerprint — mixing these up (e.g. embedding one shared user key in your app) violates AcoustID's usage terms
The free AcoustID web service is explicitly non-commercial only; commercial use requires signing up separately through acoustid.biz
Fingerprint submissions are not immediately queryable — code that submits then immediately looks up the same fingerprint must account for asynchronous import via the submission_status endpoint, not assume synchronous availability
