ES·pera API

ES·pera is an independent Spanish-language observatory that gathers scattered official Spanish National Health System (SNS) and autonomous-community publications on healthcare waiting lists and hospital activity, and republishes them as comparable, provenance-preserving open data. It exposes a free, open, unauthenticated read-only REST API (OpenAPI 3.1 at /api/v1) covering hospital entities, national activity metrics and autonomous waiting-list observations, served from immutable content-addressed data releases. Discovery is via an RFC 9727 API catalog, an llms.txt, and a provider-published Agent Skill; there is no MCP server, no A2A agent card, and no client SDK.

ES·pera API publishes 1 API on the APIs.io network: ES·pera Public Data API. Tagged areas include Healthcare, Open Data, Waiting Lists, hospital activity, and Spain.

ES·pera API’s developer surface includes documentation, authentication, changelog, and 14 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/es-pera: open an issue to ask a question, or submit a pull request to add artifacts.
