18Birdies

18Birdies is a golf technology company behind the 18Birdies mobile app — a golf GPS rangefinder, digital scorecard, shot- and stat-tracking platform and social network for golfers, founded in 2014. The app combines Google Maps-derived course imagery and elevation with hole-by-hole GPS distances, 3D green maps, wind and slope adjustment, club recommendations, strokes-gained analytics, an AI Swing Analyzer, handicap tracking, side games and tournament/league management across a worldwide golf course database. It operates a freemium consumer subscription (a free tier plus Premium) with companion Apple Watch and Wear OS experiences. 18Birdies runs a production backend at api.18birdies.com that serves its own mobile clients, but as of this profiling pass it publishes no public developer program, no API reference, and no machine-readable contract.

18Birdies is profiled on the APIs.io network. Tagged areas include Golf, Sports, Mobile App, Location, and Geolocation.

18Birdies’ developer surface includes support, engineering blog, pricing, signup flow, and 9 more developer resources.

scored 2026-11-06 · rubric v0.27.0
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)
  • Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes

Kin Score — facets with the most composite points still available (weight × headroom):
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/18birdies/apis.yml: open an issue on github.com/api-evangelist/18birdies to ask a question or point us at an artifact you publish.
