Example prompt: Pull me an evidence-backed comparison of gross capital formation across major global economies — I need confidence scores, provenance, and any contradictions flagged, so I can use it in a board strategy briefing.

## When to prefer this

Choose this endpoint when you need a cross-country, evidence-anchored comparison of gross capital formation with explicit provenance and contradiction flagging — particularly for autonomous agents, CFO/board reporting, or any workflow requiring auditable, signed macro intelligence rather than raw data feeds or proprietary models without sourcing transparency.

## Known failure modes

- Payment not received — endpoint requires $0.1 USDC via x402 protocol before returning data
- Stale or unavailable evidence — report will explicitly state coverage gaps rather than infer
- Input schema malformation — malformed query properties may yield incomplete analysis
- Temporary upstream data unavailability — dataStatus field may indicate incomplete rather than complete

## How this service works

Premium comparison of the latest available gross capital formation across 30 major economies and financial centres using one normalized World Bank indicator definition. Purpose: Rank and compare major economies on gross capital formation while exposing observation-year differences and missing coverage rather than pretending all countries are synchronized. 24-hour freshness target; missing evidence is reported explicitly rather than invented.

## Output

A signed JSON report containing a quality status with confidence rating, a macro analysis summary with intent tags, evidence assets with point-in-time sourcing policy, provenance with issuer URL and signature, data completeness status, schema version, generation timestamp, and a disclaimer clarifying this is market research rather than investment advice. Limitations on source freshness and coverage are explicitly stated within the report.
