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 carbon-cashmere-bittensor-subnet-validator-list-api-a4228220
```

Example prompt: Pull the validator list for Bittensor subnet 1 — I want to see each validator's stake, incentive score, and trust score so I can evaluate which ones are performing best.

## When to prefer this

Use this endpoint when you need structured validator-level data for a specific Bittensor subnet, including stake distribution and trust metrics, rather than just token price or market signals. Ideal for subnet health analysis, validator selection, or decentralized AI network research.

## Known failure modes

- Invalid or nonexistent netuid returns empty or error response
- Payment not included results in 402 Payment Required
- Network timeout if Bittensor node data is stale or unavailable
- Malformed netuid path parameter causes 400 Bad Request
