# Project-level pageview time series

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

Daily or monthly pageview totals across an entire Wikimedia project (e.g. all of English Wikipedia). Sourced from the Wikimedia Foundation Analytics Query Service (CC0). Useful as a denominator when computing attention share for individual articles.

## Query parameters

- `project` string — Wikimedia project domain (e.g. `en.wikipedia`, `commons.wikimedia`).
- `access` string — Access method filter (`all-access`, `desktop`, `mobile-app`, `mobile-web`).
- `agent` string — User-agent class filter (`all-agents`, `user`, `spider`, `automated`).
- `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).

## Response `200`

Chronological list of project-level pageview totals.

- EnvelopeWikipediaPageviewsAggregatePayload
  - `data` WikipediaPageviewsAggregatePayload, required — Response payload for `/pageviews/aggregate`.
    - `project` string, required — Wikimedia project domain echoed from the request.
    - `access` string, required — Access method filter echoed from the request.
    - `agent` string, required — User-agent class filter echoed from the request.
    - `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` WikipediaPageviewRow[], required — Project-level pageview totals in chronological order.
      - `project` string, nullable — Wikimedia project domain echoed from the request (e.g. `en.wikipedia`).
      - `article` string, nullable — Article title (per-article endpoint only; null for aggregate rows).
      - `access` string, nullable — Access method filter echoed from the request (`all-access`, `desktop`, `mobile-app`, `mobile-web`).
      - `agent` string, nullable — User-agent class filter echoed from the request (`all-agents`, `user`, `spider`, `automated`).
      - `granularity` string, nullable — Aggregation granularity (`daily` or `monthly`).
      - `timestamp` string, nullable — ISO 8601 UTC timestamp of the bucket (`YYYY-MM-DDT00:00:00Z`, normalised from upstream `YYYYMMDDHH`).
      - `views` integer, nullable — Pageview 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.
