# GENESIS Agent Tools — Release Guardian (Dexter Facilitator)

> GENESIS Agent Tools — Release Guardian (Dexter Facilitator) is a paid API for AI agents from genesis-agent-tools.genesisagenttools.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-01).

Analyzes differences between two API or software releases to detect breaking changes, regressions, or compatibility issues using quick or deep analysis tiers.

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 genesis-agent-tools-release-guardian-dexter-facilitator-d348c739 -d '<json body>'
```

Example prompt: Run a deep release-guardian check comparing my previous API spec to the current one — here's the previous: {prev_spec} and the current: {curr_spec} — flag any breaking changes or warnings.

## When to prefer this

Choose this endpoint when you need automated, pay-per-call release compatibility analysis between two software or API versions, especially in agentic CI/CD pipelines where you want to gate deployments on detected breaking changes. Prefer it over manual diffing when you need structured evidence and warnings in a machine-readable format, and when operating in a Base USDC x402 payment context.

## Known failure modes

- Missing or malformed 'current' or 'previous' input objects returns an error
- Invalid tier value (not 'quick' or 'deep') causes validation failure
- Payment not fulfilled via x402 results in 402 Payment Required response
- Overly large or complex release objects may time out on the Cloudflare Worker
- Empty input objects may return empty evidence and result with no useful output

## How this service works

Pay-per-call x402 APIs for autonomous agents on Base USDC: API compatibility analysis, bounded HTTP/JSON workflows, URL evidence analysis, crypto price consensus, and agent/MCP readiness checks.

## Output

Returns a JSON object with ok status, the analysis tier used, a result object containing the compatibility findings, a product identifier ('release-guardian'), an evidence array detailing observed changes, and a warnings array listing potential issues or breaking changes.
