SouthendOnSea.city

SouthendOnSea.city is an independent local information and community-participation platform for Southend-on-Sea, Essex, covering local news, community propositions and public voting, city information and the Southend Science Exhibition. Its public data API — Southend Now — serves unauthenticated, source-linked current and historical observations for the area: weather, designated bathing waters, marine conditions, modelled air quality and flood alerts. Three operations return the current snapshot, a JSON history and a CSV history, refreshed on a 1,800-second interval, with source licensing and attribution preserved in the payload. The platform is independent and unofficial and states plainly that it is not operated by Southend-on-Sea City Council, Essex Police or any election authority.

SouthendOnSea.city publishes 1 API on the APIs.io network: Southend Now API. Tagged areas include Open Data, Southend-on-Sea, Weather, Environment, and local data.

SouthendOnSea.city’s developer surface includes authentication, support, documentation, and 13 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/southendonsea: open an issue to ask a question, or submit a pull request to add artifacts.

  note: 'Submitted via apis.io/add on 2026-08-23 from hello@southendonsea.city and rated 71 (exemplar) by the gate — the highest-rated
    submission seen in this sweep, and it holds up. Unusually, the submitted APIs.json URL is CORRECT. It resolves at both
    /.well-known/apis.json and /apis.json, an invented control path returns a real 404, and every property it declares was
    fetched and confirmed. The OpenAPI is served as application/vnd.oai.openapi+json;version=3.0 — the correct media type,
    which almost no provider sets. The API was exercised anonymously: GET /api/southend-now returned live observations with
    real beach records, a licence note and a generatedAt timestamp, and the CSV history endpoint returned text/csv. No key,
    no signup. ONE THING RECORDED CAREFULLY. This is NOT a council or government API and must not be presented as one. The
    operator states on its own llms.txt that it is "independent and unofficial, and is not operated by Southend-on-Sea City
    Council, Essex Police or an election authority", and that its articles reorganise official Essex Police and council updates.
    The data is source-linked to official publishers; the platform is a third party republishing it.'
