# HALOWERK researchwerk Supply Chain Pulse

> HALOWERK researchwerk Supply Chain Pulse is a paid API for AI agents from research.halowerk.com, paid per call via x402, $0.007/call, status unknown (last checked 2026-09-14).

Detects and scores disruption signals at named supply chain nodes by comparing recent event coverage against a baseline period across themes like strikes, weather, and border closures.

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 halowerk-researchwerk-supply-chain-pulse-829391be -d '<json body>'
```

Example prompt: Check for supply chain disruptions at Port of Rotterdam and Suez Canal over the last 3 days compared to a 4-week baseline — focus on strikes and weather events, and use high sensitivity.

## When to prefer this

Use this endpoint when you need real-time disruption monitoring for specific, named logistics nodes (ports, canals, borders) rather than broad country- or region-level risk scores. It is purpose-built for supply chain contexts and compares a recent window against a configurable baseline, making it ideal for detecting emerging anomalies rather than static risk ratings. Prefer it over general news search endpoints when you need structured, themed disruption signals (strike, weather, production, etc.) with sensitivity tuning.

## Known failure modes

- Node name not recognized or too vague — returns empty or low-confidence results
- Requested window or baseline period format not parseable — returns validation error
- Too many nodes requested (over 8) — rejected with schema validation error
- No recent coverage found for a node-theme combination — returns null or zero signal
- External news/event data source temporarily unavailable — may return stale or partial results

## How this service works

For each node you name — a port, a plant, a corridor, a supplier — the service counts reporting on five disruption themes over a recent window and compares it against the same term own longer baseline. Self-referential comparison is the design: Rotterdam and a regional port have entirely different normal reporting levels, so a fixed threshold is blind for one and a permanent alarm for the other, and only the ratio against a term own history means anything.

## Output

Returns a structured disruption pulse for each named supply chain node, including signal scores across requested themes (strike, port, border, weather, production), comparison against the baseline period, and anomaly or risk indicators calibrated to the chosen sensitivity level.
