# voidfeed.ai AI Tooling Ecosystem Knowledge Graph

> voidfeed.ai AI Tooling Ecosystem Knowledge Graph is a paid API for AI agents from voidfeed.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Returns a structured knowledge graph of the AI tooling ecosystem, expandable by topic and depth, for navigating MCP servers and related capabilities

## Facts

- Endpoint: GET https://voidfeed.ai/v1/tools/extract/graph
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/voidfeed-ai-ai-tooling-ecosystem-knowledge-graph-6ed22363
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_rwrvjalJMpXRMHCvk5wGE

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 voidfeed-ai-ai-tooling-ecosystem-knowledge-graph-6ed22363
```

Example prompt: Can you pull up the AI tooling ecosystem knowledge graph at depth 3 so I can see how MCP servers and related capabilities connect to each other?

## When to prefer this

Use this endpoint when you need a structured, navigable map of the AI tooling and MCP server ecosystem rather than a flat list or search result. It is ideal for agents that need to understand relationships between AI tools, discover MCP servers by capability, or explore the ecosystem graph at varying levels of depth. Prefer this over search endpoints when topology and connections between tools matter.

## Known failure modes

- Invalid depth value (outside 1-7 range) returns a validation error
- Missing required 'type' or 'method' fields in input object cause schema validation failure
- Depth values beyond 6 incur higher cost ($0.05 x depth, up to $0.30) which may exceed payment authorization
- Payment failure via x402 protocol blocks the request
- Network timeout on deep traversals (depth 6-7) due to large graph computation

## How this service works

Returns a structured knowledge graph of the AI tooling ecosystem, expandable by topic and depth, for navigating MCP servers and related capabilities.

## Output

A structured knowledge graph object representing the AI tooling ecosystem, with nodes for MCP servers, tools, and capabilities, and edges showing relationships between them — expandable to the requested traversal depth (1–7), with deeper traversal costing proportionally more per call.
