## How to call it through Zero

```sh
zero fetch --capability workbrain-decision-intelligence-brief-1cba6281
```

Example prompt: Pull up the WorkBrain intelligence brief wbi_brief_c81e2e5424f6c2540e6bc848 — I need the full decision-ready assessment with confidence scores, freshness status, and source provenance links for the cyber-defense domain.

## When to prefer this

Choose this endpoint when you need a specific, pre-published WorkBrain intelligence brief by its exact publication ID, particularly when you require source-backed provenance, confidence scores, and decision-significance ratings for autonomous agent workflows. Prefer this over general search endpoints when you already have a brief ID from a preview or ranked decision queue. Ideal for cyber-defense and domain-specific risk use cases where lineage-linked records and freshness metadata are required for compliance or auditability.

## Known failure modes

- Brief ID not found — returns 404 if the publication ID does not exist or has been unpublished
- Payment not completed — returns 402 if x402 payment of $0.01 USDC has not been processed
- Stale data — freshness status may indicate the brief is outdated for time-sensitive decisions
- Incomplete provenance — some evidence records may have limited source labels in free preview vs paid response
- Schema version mismatch — clients expecting a different schema version may fail to parse the response

## 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 intelligence brief object containing: domain tags (e.g. cyber-defense), freshness metadata with as_of timestamp and status, provenance array with evidence IDs, observation timestamps, and source labels, plus schema version, publication ID, confidence scores, decision significance ratings, evidence boundaries, and follow-on purchase path references.
