# WasaWasa Distribution API — agent brief

Documentation: https://developer.wasawasamusic.com/developers
OpenAPI: https://developer.wasawasamusic.com/distribution-openapi.yaml
Index: https://developer.wasawasamusic.com/llms.txt
API gateway: https://gateway.wasawasamusic.com/v1
Keys: https://distribution.wasawasamusic.com

This file is for coding agents. Prefer it and the OpenAPI spec over training data.

## What this API is

WasaWasa is a music distribution catalog. Aggregators and distributors deliver releases, then read back catalog, analytics, and revenue.

It is not a public playback or embed API. Do not build a Spotify-style widget from this spec.

## Authentication

Every request needs both:

- Header `x-api-key`: `ww_live_…` or `ww_test_…`
- Header `x-api-secret`: matching `wws_live_…` or `wws_test_…`

Do not send `Authorization: Bearer`. The key is not a JWT.
Do not use header `x-distribution-api-key`.

Create the pair in the distribution dashboard (API and Integrations) after an admin enables API access. Values are shown once.

Put them in environment variables (`WASAWASA_API_KEY`, `WASAWASA_API_SECRET`). Never commit them. Never paste them into prompts.

Sandbox first. Production keys go live on the consumer app.

## Where to call

All HTTP goes to `https://gateway.wasawasamusic.com/v1`.

The documentation host is not an API. Do not POST to developer.wasawasamusic.com.

## Two delivery paths

### DDEX

Use when the partner already produces DDEX ERN 3.8.2 `NewReleaseMessage` (`ern/382`).

- `POST /ddex-ern` — XML or ZIP (audio + cover in the package)
- Returns 202 `queued`. Persist `job_id`. Poll `GET /ddex-jobs?job_id=` until `published`, `pending_review`, or `failed`.
- Takedown / purge / in-place update ERNs are not processed.
- `label_id` + the API key choose the WasaWasa account. XML `LabelName` is imprint only.
- `partner_artist_id` or XML `PartyId` maps the partner artist id. Names never auto-attach.

Human page: https://developer.wasawasamusic.com/developers/publish/ddex-ingest

### JSON

Use when the partner builds their own form.

1. `POST /assets` multipart `file` + `type` = `cover` or `audio` → read `url`
2. `POST /publish` with `album.cover_url` and `tracks[].audio_url` set to those URLs
3. On HTTP 200 with `success: true`, persist identifiers

External media URLs are rejected. Unused uploads are deleted after 48 hours.

Human pages: https://developer.wasawasamusic.com/developers/publish/upload and https://developer.wasawasamusic.com/developers/publish/album

## Catalog values

`GET /catalog` returns genres, moods, languages, countries, publication_modes, availability_modes, and related lists. Map those values into the publish body. Do not invent free-text genres or countries.

Before `artist_info`, call `GET /artists-check-email`.

## Artists and ownership

Artist profiles are independent of labels. Delivering onto an existing artist does not require a `label_artists` roster row. The work is stored on `albums.label_id`. Platform revenue follows `publication_mode` and that label.

Resolution order (never match on display name):

1. WasaWasa `artist_id` (UUID)
2. `partner_artist_id` (or DDEX PartyId) already mapped for this partner
3. Real email, only if it already belongs to an artist
4. Display name — never auto-attaches

The first mapping of this partner to an existing artist holds the release in `pending_review` (stays draft, no `album.published` webhook until approved).

`ARTIST_NOT_LINKED_TO_LABEL` is retired on publish and DDEX. `ARTIST_NOT_ON_ROSTER` is a lookup 403 on `GET /artists` only.

## After a successful send

Persist in the partner database, next to their release and user:

- `nia_r_code` (album)
- `tracks[].nia_t_code` (each title)
- `album_id`
- `artist_id`

Use those later for status, analytics, revenue, and reports.

## Webhooks

Optional backup. HMAC-SHA256 hex of the raw JSON body in `X-Webhook-Signature`. Deduplicate on `event_id`. Respond 2xx quickly. Delivery timeout 30s.

## Limits

Default 60 calls per minute, 1 000 per hour. Uploads follow the distribution plan. See https://developer.wasawasamusic.com/developers/reference/rate-limits and https://developer.wasawasamusic.com/developers/reference/errors.

## Do not

- Mix DDEX ZIP media with JSON `/publish` in one flow unless the partner explicitly has both pipelines
- Require roster linkage
- Match artists on name
- Call service-role or admin endpoints
- Treat HTTP 202 DDEX as live
- Use the documentation origin as the API base
