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
Returns a JSON object with a numeric safety score (0–100), a verdict string ('GO' or 'NO-GO'), a list of human-readable reasons, a confidence float (0–1), an evidence object with package name, version, and vulnerability count, and a receipt containing an evidence SHA-256 hash and a verification URL for auditing.
Example use cases
Pre-install npm package security check
“I want to add express@4.18.2 to my project — run a preflight on it as an npm_dependency, require it has a license, and flag anything if it has more than 0 known vulnerabilities.”
Vetting a GitHub repo before forking
“Can you run a preflight check on the GitHub repository github.com/honojs/hono? I want to make sure it's been pushed to in the last 90 days and is safe to use.”
Automated CI dependency gating
“Before my pipeline installs lodash@4.17.21, do a decision preflight check on it as an npm_dependency — require the latest version and reject it if there are any known vulnerabilities.”
Technical details
Endpoint
POSThttps://api.salt19.com/v1/agent-decision-preflightWhen to prefer
Choose this endpoint when an AI agent or automated pipeline needs a structured, signed GO/NO-GO decision on an npm package or GitHub repository before installation or use — especially when you need an auditable evidence receipt, vulnerability scoring, and license/recency constraints evaluated in a single call. Prefer it over raw OSV or GitHub API queries when you want a confidence-scored verdict with cryptographic provenance rather than raw data.
Side effects
- Unknown or misspelled package name returns an error or low-confidence result
- Version string not found in registry causes evidence lookup failure
- OSV database unavailable may result in degraded confidence score
- Missing required fields (decision_type or target.package) returns a 400-level error
- Payment not completed (x402 flow failure) prevents response delivery
