# SALT19 Dependency Upgrade Go/No-Go Decision Engine

> SALT19 Dependency Upgrade Go/No-Go Decision Engine is a paid API for AI agents from api.salt19.com, paid per call via x402, $0.16/call, status unknown (last checked 2026-09-15).

Analyzes a proposed package version upgrade and returns a scored go/no-go verdict covering breaking changes, security implications, runtime compatibility, and peer dependency conflicts.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability salt19-dependency-upgrade-go-no-go-decision-engine-d4ce3cf7 -d '<json body>'
```

Example prompt: Can you run a go/no-go analysis on upgrading the axios package from version 1.6.0 to 1.7.2 in a Node.js 20 environment with an Express framework — I need to know if there are breaking changes, security issues, or peer conflicts before I merge this?

## When to prefer this

Choose this endpoint when an AI agent or CI/CD pipeline needs a structured, scored recommendation on whether to proceed with a specific dependency upgrade — especially when you need explicit signals on breaking changes, OSV security records, peer conflicts, and runtime compatibility in a single call. Prefer this over generic vulnerability scanners when you want an actionable GO/NO-GO verdict with a confidence score rather than raw advisory data.

## Known failure modes

- Missing required fields (package, current_version, target_version) return a 400 validation error
- Unknown or private packages may result in NOT_PROVEN states across all dimensions with lower confidence scores
- Highly unusual version strings may fail parsing and return an error
- Overly long or malformed constraint strings may be rejected
- Network or upstream registry timeouts may cause 503 responses

## 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 confidence score (0–1), a GO or NO-GO verdict, an upgrade recommendation, and structured states for breaking changes (with version change type), runtime compatibility, security implications (with OSV record counts for both versions), peer dependency conflicts, and a list of recommended tests to validate the upgrade.
