Salus

Salus provides runtime validation and governance for AI agents. It sits between an agent and its tools as a policy-aware proxy that intercepts each action before it executes, then clarifies, rewrites, escalates for human review, or blocks it against organizational policies — managing commit-time risk on financial transfers, appointment changes, and data modifications before they alter customer data, finances, or records. Integration requires only an endpoint URL change (no agent rewrite), and Salus works across OpenAI, Anthropic, Gemini, LangChain, LangGraph, CrewAI, Retell, Vapi, and custom tools. Capabilities include evidence-based validation, PII detection, budget and loop protection, idempotency checks, human-in-the-loop escalation, self-repair of blocked actions, and integrated evals and observability. Salus is a Y Combinator (Winter 2026) company based in San Francisco.

Salus is profiled on the APIs.io network. Tagged areas include Company, AI Agents, Runtime Validation, Agent Governance, and AI Safety.

Salus’ developer surface includes pricing and 3 more developer resources.

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/salus: open an issue to ask a question, or submit a pull request to add artifacts.
