## 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 ai-hedge-fund-knowledge-graph-api-3beea72f
```

Example prompt: Pull the knowledge graph from the AI Hedge Fund research API so I can see how the financial entities and relationships are connected — filter by the properties I care about for this sector analysis.

## When to prefer this

Choose this endpoint when you need to explore the structural topology of a financial research knowledge graph — specifically the entity nodes and relationship edges — rather than retrieving flat tabular data or time-series market data. Best suited for graph-based reasoning tasks over institutional research entities.

## Known failure modes

- Missing or invalid 'properties' filter parameter returns empty or malformed graph
- Payment not processed (402 response) if x402 USDC payment of $0.25 is not attached
- Rate limiting if too many requests are made in a short window
- Graph may return with zero nodes/edges if no matching entities found for given properties filter
- Service unavailability returns 5xx error with no graph data

## How this service works

Read-only x402 research APIs. No trading, broker, or execution is exposed.

## Output

Returns a JSON object containing a knowledge graph with a count of nodes and edges (e.g. 12 nodes, 18 edges) and a unique runId string identifying this graph retrieval session.
