Pexafy

Pexafy is a semantic (meaning-based) search engine over free-licence stock photography. One request queries nine free stock-photo libraries — Unsplash, Pexels, Pixabay, StockSnap, Picjumbo, Kaboompics, Burst, Skitterphoto and NegativeSpace, plus Wikimedia Commons since description 1.3.0 — and returns every photo in one normalised JSON schema with dimensions, dominant colour, orientation, photographer, licence and a ready-made attribution string. Queries are written as full sentences in any of 100+ languages and ranked by meaning rather than keyword overlap; an image can be posted instead of text to find visually similar photos, and results can be filtered by colour, orientation, licence, source, photographer or date. The API is self-serve — a key is issued immediately from the dashboard with no application review and no mandatory download-tracking callback — and the same catalogue is exposed to LLM clients through a hosted, OAuth-protected MCP server at mcp.pexafy.com.

Pexafy publishes 5 API contracts indexed on the APIs.io network, including Collections API, Facets API, Photos API, and 2 more. Tagged areas include Image, Photos, Stock Photos, Image Search, and Semantic Search.

Pexafy’s developer surface includes pricing, support, engineering blog, authentication, CLI, changelog, and 25 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):

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
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too
Pagination +5 pts — share of collection GETs (an array, or one wrapped in data/items/results ...) that declare a page/limit/offset/cursor parameter, a Link header or a next/cursor field; na with no collection GETs
Agentic Commerce Well-Known Document +5 pts — a parsing /.well-known/ucp.json or acp.json declaring a version and at least one service — `self` when its endpoints are on the provider's own domain, `platform` when they are on a vendor's

4 more unmet checks in the Agent Readiness table above.

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

Contract Quality scores 50.4 — up to +12.4 composite points
Contract Governance scores 18.2 — up to +9.8 composite points
Developer Ergonomics scores 73.2 — up to +5.4 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/pexafy/apis.yml: open an issue on github.com/api-evangelist/pexafy to ask a question or point us at an artifact you publish.

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.

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.
