# ForwardLane Repository Neighbors Lookup

> ForwardLane Repository Neighbors Lookup is a paid API for AI agents from agents.forwardlane.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-17).

Returns the neighbor list and total neighbor count for a given repository node in the ForwardLane code-graph knowledge base.

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 forwardlane-repository-neighbors-lookup-e5c3ac1b
```

Example prompt: What are the graph neighbors of the 'langchain' repository in the ForwardLane code graph?

## When to prefer this

Use this endpoint when you need to retrieve the direct graph neighbors of a specific, known repository by name from the ForwardLane code knowledge graph. It is the most efficient single-hop lookup for adjacency data. Prefer this over the full-graph or search endpoints when you already know the exact repository name and only need its connected nodes, not a broader search or full subgraph traversal.

## Known failure modes

- 404 Not Found — repository name does not exist in the ForwardLane graph index
- Incorrect or misspelled repository name returns 404
- Repository exists but has zero neighbors (empty neighbor list returned)
- Rate limiting or payment failure due to x402 protocol issues

## How this service works

Returns repo, total_neighbors, and the neighbor list for one repository. Returns 404 if the repository is unknown.

## Output

Returns a JSON object containing the repository name, total number of neighbors (total_neighbors), and a list of neighbor repository nodes. Returns a 404 error if the repository name is not found in the graph.
