Plai Labs

Plai Labs is the a16z-backed venture founded by ex-MySpace leaders Aber Whitcomb and Jim Benedetto (with Chris DeWolfe); its plailabs.com domain now redirects to Salt AI (salt.ai), the team's enterprise AI platform. Salt AI is a visual plus full-code AI workflow platform positioned as "Contextual AI for Regulated Enterprise" that deploys governed, auditable, model-agnostic AI workflows inside a customer's own infrastructure (behind the firewall, zero public data egress to external model providers, immutable audit trails) for life sciences, financial services, energy, and public-sector customers. Workflows built in the Salt visual builder can be deployed as production HTTP APIs that execute asynchronously and return their results via a webhook callback to a caller-supplied URL.

Plai Labs publishes 1 API on the APIs.io network. Tagged areas include Company, Artificial Intelligence, AI Workflows, Agents, and LLM.

The Plai Labs catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Plai Labs’ developer surface includes documentation, API reference, getting-started guide, engineering blog, support, signup flow, and 10 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health 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/plai-labs: open an issue to ask a question, or submit a pull request to add artifacts.
