# audd-openapi

3+
[![CI](https://github.com/AudDMusic/audd-openapi/actions/workflows/ci.yml/badge.svg)](https://github.com/AudDMusic/audd-openapi/actions/workflows/ci.yml)
4+
5+
The canonical OpenAPI 3.1 specification for the [AudD](https://audd.io) music recognition API.
6+
7+
This repository is the source of truth that all official AudD SDKs build their typed models against. Third parties can also use this spec to generate their own clients.
8+
9+
| File | Purpose |
10+
|---|---|
11+
| [`openapi.yaml`](./openapi.yaml) | OpenAPI 3.1 spec covering every public AudD endpoint |
12+
| [`fixtures/`](./fixtures/) | Real captured API responses, PII scrubbed — used by every SDK's contract tests |
13+
| [`tests/validate.py`](./tests/validate.py) | Validates each fixture against its schema in `openapi.yaml` |
14+
| [`tests/capture_fixtures.py`](./tests/capture_fixtures.py) | Re-capture fixtures from the live API (requires an api_token) |
15+
16+
## What's covered
17+
18+
- **Standard recognition** — `POST/GET https://api.audd.io/`
19+
- **Enterprise recognition** — `POST https://enterprise.audd.io/` (hours- to days-long files)
20+
- **Stream management** — `setCallbackUrl`, `getCallbackUrl`, `addStream`, `getStreams`, `setStreamUrl`, `deleteStream`
21+
- **Longpoll** — `GET /longpoll/`
22+
- **Custom catalog upload** — `POST /upload/` (special access required)
23+
- **Lyrics search** — `POST /findLyrics/`
24+
25+
The WebSocket recognition variant is intentionally not modeled — AudD recommends the HTTP endpoints for all use cases.
26+
27+
## Validate locally
28+
29+
```bash
30+
python -m venv .venv
31+
source .venv/bin/activate
32+
pip install -r requirements-dev.txt
33+
python tests/validate.py
34+
```
35+
36+
To re-capture fixtures from the live API:
37+
38+
```bash
39+
AUDD_TEST_TOKEN_STD=... AUDD_TEST_TOKEN_ENTERPRISE=... \
40+
python tests/capture_fixtures.py
41+
python tests/scrub_fixtures.py
42+
```
43+
44+
## Generate a client
45+
46+
This spec is hand-written and validates against real fixtures. You can use it with any OpenAPI-compatible code generator. Note that AudD's official SDKs are hand-written rather than generated — to maximize idiomatic feel in each language — but they validate against this same spec.
47+
48+
## Contract drift detection
49+
50+
When this repo lands a change to `openapi.yaml` or `fixtures/`, a workflow fires `repository_dispatch` events at every `audd-<lang>` SDK repo to re-run their contract tests against the new spec. Each SDK also runs the same tests on a nightly cron as a safety net.

# Fixtures
2+
3+
Real captured AudD API responses, used as the source of truth for SDK contract tests in every `audd-<lang>` repo.
4+
5+
| File | Source | Endpoint | Notes |
6+
|---|---|---|---|
7+
| `recognize_basic.json` | live capture | `POST api.audd.io/` | Standard recognition without metadata |
8+
| `recognize_with_metadata.json` | live capture | `POST api.audd.io/` | Standard recognition with `return=apple_music,spotify,deezer,napster,musicbrainz` |
9+
| `recognize_custom_match.json` | synthesized from design spec | `POST api.audd.io/` | Custom-catalog match shape (only `timecode` + `audio_id`) — can't easily capture live without enterprise custom-catalog access |
10+
| `enterprise_with_isrc_upc.json` | live capture (enterprise token, `limit=1`) | `POST enterprise.audd.io/` | Enterprise success with ISRC and UPC fields |
11+
| `error_900_invalid_token.json` | live capture | `POST api.audd.io/` | Invalid api_token |
12+
| `error_700_no_file.json` | live capture | `POST api.audd.io/` | No file or url sent |
13+
| `error_19_no_callback_url.json` | live capture | `POST api.audd.io/getCallbackUrl/` | The "no callback URL configured" signal — server returns code 19 (catch-all "Internal error") |
14+
| `error_902_stream_limit.json` | live capture | `POST api.audd.io/addStream/` | Stream slots exhausted on subscription |
15+
| `error_904_enterprise_unauthorized.json` | live capture | `POST enterprise.audd.io/` | Standard token denied at enterprise endpoint |
16+
| `getStreams_empty.json` | live capture | `POST api.audd.io/getStreams/` | Empty stream list |
17+
| `longpoll_no_events.json` | live capture | `GET api.audd.io/longpoll/` | Longpoll timeout response (no new events) |
18+
| `streams_callback_with_result.json` | from docs.audd.io/streams.md | callback POSTed by AudD to user webhook | Recognition-result variant of the callback payload |
19+
| `streams_callback_with_notification.json` | from docs.audd.io/streams.md | callback POSTed by AudD to user webhook | Notification variant (stream connectivity) |
20+
21+
Synthesized fixtures match the documented response shapes 1:1; they're called out explicitly so reviewers know which were captured live.
22+
23+
To re-capture: see `tests/capture_fixtures.py`. **Always pass `limit=1` for enterprise endpoint calls.**
