Espial
Espial is an open-source, web-based bookmarking server that supports multiple user accounts and self‑hosted deployments.

The project provides a Docker‑based quick‑start, a CLI, and a REST API for programmatic bookmark management.
Espial is profiled on the APIs.io network. Tagged areas include Company, Bookmarking, OpenSource, Haskell, and Docker.
Espial’s developer surface includes documentation, API reference, and 3 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 could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
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):
- Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
- MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
- Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
- 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)
- Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
- A2A Agent Card +8 pts — a2a/
-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
13 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
- Contract Quality scores 0.0 — up to +25.0 composite points

- Developer Ergonomics scores 16.7 — up to +16.7 composite points
Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.
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 the provider profile at artifacts.apis.io/espial/apis.yml: open an issue on github.com/api-evangelist/espial to ask a question or point us at an artifact you publish.
