Ploid

Ploid is an applied AI lab building a people search and intelligence platform: a living index of more than two billion people available through a web app, a REST API, a CLI, and a hosted MCP server. The Ploid Public API (OpenAPI 3.1, 31 operations on api.ploid.com) covers synchronous people search, person resolution and evidence-backed person research runs, contact and social enrichment, public LinkedIn reads, monitors, and account usage and credit budgets, metered in ACU credits.

Ploid publishes 10 API contracts indexed on the APIs.io network, including Account API, Discovery API, Enrichment API, and 7 more. Tagged areas include Company, People Data, People Search, Contact Enrichment, and Sales Intelligence.

The Ploid catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 1 Spectral governance ruleset.

Ploid’s developer surface includes CLI, authentication, documentation, API reference, getting-started guide, pricing, signup flow, and 33 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/.
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/ploid: open an issue to ask a question, or submit a pull request to add artifacts.
