How this service works
SALT19 is an independent applied AI systems lab behind EvoMind governed cognition, the MCP-native Agent Utility Grid, the ARCS research community, AeroClear UAS flight intelligence, and practical software for real-world work.
Output
A JSON object containing: a 'verdict' field ('GO' or 'NO-GO'), a 'reasons' array explaining the decision (e.g. vulnerability status, license presence, publication activity), an 'evidence' object with the package name, version, resolved license, and vulnerability count, and a 'policy_version' string identifying the policy applied.
Example use cases
CI/CD dependency safety gate
“Before we merge this PR, run a go/no-go check on express version 4.18.2 — flag it if there are any OSV vulnerabilities, a non-permissive license, or it looks abandoned.”
Vetting a new open source library
“I'm thinking of adding zod version 3.22.4 to our project — can you check if it gets a GO verdict on safety, licensing, and recent activity?”
Auditing a flagged transitive dependency
“Our security team flagged lodash version 4.17.21 as a potential risk — can you run a dependency policy check on it and tell me the verdict and reasons?”
Technical details
Endpoint
POSThttps://api.salt19.com/v1/dependency-go-no-goWhen to prefer
Use this endpoint when you need a structured, policy-backed GO/NO-GO verdict on a software package rather than raw vulnerability data alone. It is ideal for automated dependency gates in CI/CD pipelines, agent-driven code review, or any workflow requiring a single authoritative decision combining vulnerability, license, and maintenance signals under a versioned policy. Prefer this over manually querying OSV or npm registries when you want a normalized, actionable verdict without post-processing.
Side effects
- Unknown or misspelled package name returns an error or NO-GO with no evidence
- Invalid or malformed version string may return a validation error
- Package not found in the vulnerability or registry database may result in incomplete evidence
- Rate limiting or payment failure (x402) results in 402 response and no verdict
- Network timeouts if upstream OSV or registry APIs are slow
