Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 knowledge-graph-compressor-mcp-667803b3 -d '<json body>'
```

Example prompt: Can you compress this knowledge graph data for me so it takes up less space and is faster to transmit? Here's the graph payload: {serialized graph data}.

## When to prefer this

Choose this endpoint when you need to reduce the size of knowledge graph or semantic graph data for storage efficiency, faster transmission, or fitting within token/memory constraints. Particularly useful in AI agent pipelines where large context graphs need to be compacted between steps.

## Known failure modes

- Invalid or malformed graph data input returns an error
- Data string that is not a recognizable graph format may produce unexpected output
- Very large graph payloads may time out or exceed processing limits
- Empty or null data field results in a processing error
- Non-UTF8 encoded data may cause parsing failures

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

A compressed representation of the input knowledge graph data, with reduced size while preserving the essential graph structure and relationships. The response contains the processed, compacted graph payload.
