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.
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 github.com/api-evangelist/builder-prime: open an issue to ask a question, or submit a pull request to add artifacts.

  description: Builder Prime's REST "Open API" — the tenant-scoped integration surface used to create leads and clients, and
    to read clients, employees, projects, appointments, appointment types and appointment results. Authenticated with a per-tenant
    secret key issued from Admin > Integrations > Open API and sent in the x-api-key header; each key is granted named permissions
    (for example clients.create). Resources are individually versioned in the path (/api/<resource>/v1). Builder Prime publishes
    no OpenAPI definition and, as of this probe, no longer publishes a public endpoint reference.

  x-base-url-note: Builder Prime documents a per-tenant base host — the customer's own login subdomain (for example https://johnsfloors.builderprime.com).
    The shared application host app.builderprime.com serves the same /api/<resource>/v1 paths and is recorded here as a real,
    non-placeholder baseURL.
