## 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-brief-retrieval-0935f1f0
```

Example prompt: Pull the WorkBrain intelligence brief wbi_brief_508e3c75dfe95c8ac7286f6a and give me the full cyber-defense risk assessment with source links, confidence score, and freshness status.

## When to prefer this

Choose this endpoint when you need a complete, publication-approved intelligence brief for a specific known WorkBrain brief ID, particularly for cyber-defense domains, and require full provenance, freshness metadata, and confidence scores rather than a free preview. Prefer this over sibling endpoints when you already have the brief ID and need the full paid payload with lineage-linked evidence and decision queues.

## Known failure modes

- 402 Payment Required — USDC payment of $0.01 not fulfilled before request
- 404 Not Found — brief ID does not exist or has been unpublished
- 401 Unauthorized — missing or invalid authentication credentials
- 410 Gone — brief has been superseded and removed from active publication
- 503 Service Unavailable — WorkBrain intelligence pipeline temporarily offline
- Stale data — freshness status may indicate the brief is out-of-date for time-sensitive decisions

## How this service works

Source-backed, decision-ready intelligence for agents. Compare free previews, then retrieve complete assessments, ranked decision queues, publication-approved changes, domain-specific risk briefs, and lineage-linked records. Paid JSON preserves freshness, confidence, public source links, public-safe provenance, decision significance, evidence boundaries, and follow-on purchase paths.

## Output

Returns a JSON object conforming to workbrain.published-intelligence/v1 schema, including: domain tags (e.g. cyber-defense), freshness object with as_of timestamp and status, provenance array with evidence IDs and source labels, object_kind, publication_id, schema_version, confidence scores, decision significance indicators, and follow-on purchase paths.
