How it is scored
13 checks worth 42 points, grouped by the artifact each one reads. A facet's sub-score is its awarded points normalized against the points that were actually applicable to that provider — a check needing an artifact the provider does not publish at all is N/A, and leaves both sides of the fraction.
Developer Ergonomics ·
ergonomics| Check | Rule | Points |
|---|---|---|
| Developer portalA dedicated developer portal — one front door, rather than API information scattered through a marketing site. | common[].type includes "DeveloperPortal" (alias-aware) | 4 |
| DocumentationNarrative documentation explaining how the API works and how to use it. | common[].type includes "Documentation" | 4 |
| API referenceA complete endpoint-level reference — distinct from narrative docs, and what a developer returns to after their first call. | common[].type includes "APIReference" (alias-aware) | 3 |
| Getting started guideAn explicit quickstart. The artifact most correlated with a developer reaching a first successful call, which is why it outscores the reference itself. | common[].type includes "GettingStarted" or "Quickstart" | 5 |
| Authentication documentedAuthentication is documented as its own topic. Auth is where most integrations stall, and burying it inside a general guide is where most developers give up. | common[].type includes "Authentication" | 5 |
| At least one SDKAt least one client library, so a consumer is not writing HTTP plumbing before writing anything of their own. | count(common[].type == "SDK" alias-aware) >= 1 | 3 |
| Three or more SDKsThree or more languages covered — evidence of investment in a real developer audience rather than one favored stack. Awarded on top of the first SDK. | count(common[].type == "SDK" alias-aware) >= 3 | 4 |
| Command-line interfaceA CLI, which is how the API gets used in scripts, CI, and exploration. | common[].type includes "CLI" | 3 |
| Console or sandboxSomewhere to try the API without wiring up credentials and a project first. | common[].type includes "Console" or "Sandbox" or "Playground" | 3 |
| Postman collectionA runnable collection — the fastest path from reading about the API to calling it.PROVENANCE-GRADED IN 0.18.3: 610 of the 729 providers registering a Postman pointer at a file in their own repo point at one API Evangelist GENERATED from their OpenAPI — our own provenance manifest calls it `derived`. The check's description is a claim about what the provider published, and those 610 were satisfying it with our work. Same treatment agent_skill_present has had since 0.6, for the same reason.Authorship is read from the per-repo provenance manifest, not from the file: a Postman collection is JSON an importer validates, so a marker cannot go inside it. A pointer at a REMOTE url the provider hosts is unaffected — 1,622 of the 2,351 are exactly that, and they are the providers this check is for. | common[].type includes "Postman" (alias-aware), graded by who authored it | 2 |
| Agent SkillA published Agent Skill — packaged instructions for an agent to use the API correctly, rather than leaving it to infer usage from the spec.PROVENANCE-GRADED IN 0.6: 2,018 of 2,274 skill sets in the catalog were generated by API Evangelist from the provider's own specs. Provider-published agent skills exist, but they are rare — across the whole telecom sector, three. | common[].type includes "AgentSkill", graded by who authored it | 3 |
| Support channelA route to a human or a community when the documentation runs out. | common[].type includes "Support" or "HelpCenter" or "Community" | 2 |
| BlogA blog. The lightest signal in the rubric, but a live one — it shows the API is still being talked about by the people who build it. | common[].type includes "Blog" | 1 |
