CiteStamp

CiteStamp provides a free, open platform to explore citation graphs of academic papers. Users can open any paper and visualize its citations as an interactive map, with human‑signed claims and machine‑inferred edges kept separate. The service includes indie preprints and Zenodo deposits, and offers an AI‑assistant friendly API that requires no key. It aims to make scholarly citation data accessible without registration, under a CC0 license.

CiteStamp is listed with 2 APIs on the APIs.io network. Tagged areas include Citation Graph, Scholarly Metadata, Bibliography Checking, AI Integration, and Publishers.

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

CiteStamp’s developer surface includes developer portal, documentation, API reference, getting-started guide, authentication, developer console, support, and 26 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Education & Research 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):

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
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)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link

9 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 18.9 — up to +20.3 composite points
Operational Transparency scores 13.2 — up to +11.3 composite points
Access Clarity scores 50.0 — up to +10.0 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/citestamp-com/apis.yml: open an issue on github.com/api-evangelist/citestamp-com to ask a question or point us at an artifact you publish.
