## 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 edge-agents-south-africa-gross-capital-formation-intelligence-ce4a45ed
```

Example prompt: Pull the latest South Africa gross capital formation intelligence from Edge Agents — I need the evidence summary, confidence level, and any contradictions flagged, with provenance included, for a CFO briefing.

## When to prefer this

Choose this endpoint when you need structured, evidence-backed macro intelligence specifically on South Africa's gross capital formation — with explicit provenance, confidence scoring, and contradiction flagging — rather than a raw data feed or a general economic statistics API. Ideal for AI agents supporting CFOs, boards, or strategy teams who need auditable, bounded decisions with source verification at a low per-call cost ($0.01 USDC).

## Known failure modes

- Payment not received or USDC balance insufficient — HTTP 402 returned, no data delivered
- Service temporarily unavailable — upstream macro data source not reachable
- Data status incomplete — report returned but assets array empty if live evidence unavailable
- Stale data — generatedAt timestamp may reflect prior reporting period if source not yet updated
- Invalid request format — malformed query parameters may result in error response

## How this service works

Latest available South Africa gross capital formation plus a comparable annual history from the World Bank World Development Indicators API, with source, lag and revision caveats. Purpose: Give an autonomous agent a normalized, directly sourced South Africa gross capital formation series without forcing it to understand World Bank indicator codes or response shapes. 24-hour freshness target; missing evidence is reported explicitly rather than invented.

## Output

Returns a JSON object containing: a quality block with status and confidence rating, a macro analysis summary with family classification and evidence intents, an evidence block with assets and policy type, provenance with issuer and signature flag, a generatedAt timestamp, dataStatus, schemaVersion (2.0), limitations list, and a disclaimer that the output is general market research and not investment advice.
