# ForwardLane List Classes

> ForwardLane List Classes is a paid API for AI agents from agents.forwardlane.com, paid per call via MPP, $0.02/call, status unknown (last checked 2026-10-31).

## 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 agents-forwardlane-com-forwardlane-list-classes-46abe102
```

Example prompt: Show me all classes in the 'risk-engine' repository from ForwardLane's code knowledge graph — filter by class name containing 'Portfolio' and return up to 50 results.

## When to prefer this

Use this endpoint when you need to enumerate or search for code classes within the ForwardLane financial-services repository corpus — especially during technical due diligence workflows, code structure analysis, or when building a picture of a codebase's object model. Prefer this over generic code search tools when working specifically with the 151 private financial-services repositories indexed by ForwardLane.

## Known failure modes

- No matching classes found for the given name/repo filter — returns empty list
- Invalid limit value (below 1 or above 1000) — returns validation error
- Unknown repository name — returns empty list or error
- Payment failure — endpoint returns 402 if payment is not resolved
- Rate limiting or quota exceeded

## How this service works
