Open-Meteo

Open-Meteo is an open-source weather API that provides free global weather forecasts, historical reanalysis data, marine conditions, air quality indexes, and long-range climate projections through a simple REST interface requiring no API key for non-commercial use. The service aggregates data from over 30 weather models provided by 15+ national meteorological services including ECMWF, NOAA GFS, DWD ICON, Météo-France, and JMA, delivering resolutions from 1 km to 11 km updated every 1 to 6 hours. Historical data extends back to 1940 via ERA5 reanalysis, giving developers and researchers access to consistent long-term climate records alongside real-time forecasts. Commercial users who need dedicated server capacity, higher throughput, and access to extended APIs such as ensemble forecasts, seasonal outlooks, satellite radiation, and climate change projections can subscribe to paid plans priced at a flat monthly rate with no per-call overage charges. The entire server infrastructure is open-source under the AGPLv3 license and can be self-hosted, while the underlying weather data is released under CC BY 4.0.

Open-Meteo publishes 10 API contracts indexed on the APIs.io network, including Air Quality APIs API, Climate Change APIs API, Elevation API, and 7 more. Tagged areas include Weather, Forecast, Historical Weather, Air Quality, and Marine.

The Open-Meteo catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Open-Meteo’s developer surface includes documentation, engineering blog, pricing, and 9 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes

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.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Weather and Climate Data	long-tail	5.0 (thin)	-	-
Obsidian Community Plugins (third-party APIs the Obsidian plugin ecosystem integrates)	long-tail	5.0 (thin)	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
