## 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 workbrain-decision-intelligence-intelligence-change-feed-a6eda31e
```

Example prompt: Pull all WorkBrain intelligence changes since October 20, 2026 and show me what's new across cyber, financial, and geopolitical risk — include the source links and confidence scores for each change.

## When to prefer this

Choose this endpoint when you need incremental, timestamped intelligence updates rather than a full current snapshot — ideal for polling agents, change-detection workflows, or any scenario where you only want what's new since a known checkpoint. Prefer it over a full brief endpoint when minimizing data volume and cost, or when building audit trails of intelligence evolution over time.

## Known failure modes

- Invalid or missing 'since' timestamp returns an error or empty change set
- Payment failure via x402 protocol returns 402 Payment Required with no data
- Timestamps in the future return an empty changes array
- Feed may be truncated (truncated: true) if the change volume exceeds response limits — agent must paginate or narrow the time window
- Stale or unavailable upstream intelligence sources may reduce freshness of returned records

## How this service works

Buy publication-approved intelligence changes, a current decision queue, or source-linked cyber-defense, financial-market, geopolitical, and cross-domain risk briefs. Every structured response preserves public source links, freshness, confidence, and decision significance.

## Output

A JSON object containing a list of intelligence change records since the requested timestamp, with fields for the since-datetime, an array of changes (each with source links, freshness, confidence, and decision significance), total changed count, returned count, truncation flag, and schema version (workbrain.change-feed/v1).
