## 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 the-artillerist-company-change-monitor-ed7cda9e -d '<json body>'
```

Example prompt: Check Acme Logistics Inc. for any sanctions, SEC filing, legal-entity, or domain registration changes since January 1 2024, and give me a structured change summary with severity and source citations.

## When to prefer this

Choose this endpoint when you need to detect *changes* in a company's status over time rather than a one-time snapshot. It is ideal for continuous vendor due diligence workflows, periodic re-screening of existing counterparties, or comparing against a previously generated report. Prefer the Company Snapshot or Company Dossier endpoints for initial onboarding due diligence; use this endpoint for ongoing monitoring. It is particularly valuable when you need citation-backed evidence of what changed, when, and with what confidence, rather than a static company profile.

## Known failure modes

- Company not found in GLEIF, SEC EDGAR, or domain registries — partial or empty results returned with disclosed gaps
- Ambiguous company name resolving to multiple entities — may require disambiguation input
- Baseline date or prior report reference not recognized — comparison may default to a standard lookback window
- Upstream data sources temporarily unavailable — gaps disclosed in response
- Rate limiting or payment failure via x402 protocol — 402 or 429 response codes
- Insufficient identifying information to locate legal entity — low confidence score returned

## How this service works

Monitor a company or vendor for sanctions, SEC filing, legal-entity, and domain-registration changes. Compare current authoritative evidence with an earlier paid report or a supplied date and receive a structured, citation-first change summary with severity, timestamps, source URLs, confidence, and disclosed gaps. Designed for continuous vendor due diligence; it is not a legal or compliance determination.

## Output

A structured JSON change summary comparing current authoritative evidence against a prior baseline, including: detected changes categorized by type (sanctions, SEC, legal entity, domain), severity rating per change, timestamps, source URLs for each citation, confidence scores, and explicitly disclosed data gaps or limitations. The response is explicitly not a legal or compliance determination.
