# Distinct-editor activity

`GET /api/v1/news/wikipedia/editors/aggregate`

Distinct-editor counts per day or per month for a Wikimedia project. Useful as a community-health metric alongside pageviews (readership vs. contributorship). Sourced from the Wikimedia Foundation Analytics Query Service (CC0). Internally uses `activity_level=all-activity-levels`.

## Query parameters

- `project` string — Wikimedia project domain (e.g. `en.wikipedia`, `commons.wikimedia`).
- `granularity` string — Aggregation granularity (`daily` or `monthly`).
- `start_date` string, required — Earliest date to include (ISO 8601 YYYY-MM-DD, inclusive).
- `end_date` string, required — Latest date to include (ISO 8601 YYYY-MM-DD, inclusive).
- `editor_type` string, nullable — Editor-type filter (`all-editor-types`, `anonymous`, `group-bot`, `name-bot`, `user`). Defaults to `all-editor-types`.
- `page_type` string, nullable — Page-type filter (`all-page-types`, `content`, `non-content`). `content` restricts to main-namespace articles.

## Response `200`

Chronological list of distinct-editor counts.

- EnvelopeWikipediaEditorsAggregatePayload
  - `data` WikipediaEditorsAggregatePayload, required — Response payload for `/editors/aggregate`.
    - `project` string, required — Wikimedia project domain echoed from the request.
    - `editor_type` string, required — Editor-type filter (`all-editor-types` when omitted).
    - `page_type` string, required — Page-type filter (`all-page-types` when omitted).
    - `granularity` string, required — Aggregation granularity (`daily` or `monthly`).
    - `start_date` string, required — ISO 8601 start of the requested window (inclusive).
    - `end_date` string, required — ISO 8601 end of the requested window (inclusive).
    - `rows` WikipediaEditorsRow[], required — Distinct-editor counts in chronological order.
      - `timestamp` string, nullable — ISO 8601 UTC timestamp of the bucket (normalised - upstream includes milliseconds).
      - `editors` integer, nullable — Distinct editor count for the bucket.
  - `meta` SugraMeta, required — Metadata attached to every /api/v1/* response envelope.
    - `endpoint` string, required — Requested endpoint path.
    - `data_time` string, required — ISO 8601 UTC timestamp of the source data, not of the request.
    - `response_time` string, required — ISO 8601 UTC timestamp when this response was produced.
    - `provider` string, required — API name and version.
    - `source` string, nullable — Identifier of the primary upstream source used for this response.
    - `attribution` string, nullable — Human-readable attribution mandated by an upstream source (e.g. a securities regulator or self-regulatory organization). Present only on responses whose source requires the owner and source to be clearly identified. Do not remove or alter it when using the response.
    - `fallback_used` boolean, nullable — True when the primary source failed and a fallback produced the data.
    - `fallback_chain` string[], nullable — Ordered list of sources attempted, in the order they were tried.
    - `cached` boolean, nullable — True when this response was served from the internal cache.
    - `stale` boolean, nullable — True when the cached response was returned after the upstream rate-limited or errored. Clients can use this to detect degraded data.

## Other responses

- `401` — Missing or invalid `x-api-key` header. JSON body with a stable `code` distinguishing `missing_api_key` (no header sent) from `invalid_api_key` (header sent, key not accepted); any other 401 source carries the generic `unauthorized` with its detail as `reason`. Plus `hint`. `plan` is always null on 401 - an unauthenticated request has no plan; quota exhaustion is 429, not 401.
- `422` — Validation Error
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
