# Bittensor Subnet Miner Leaderboard

> Bittensor Subnet Miner Leaderboard is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Returns the top-N miners ranked by incentive for a specified Bittensor subnet, with per-miner metrics including stake, trust, emissions, consensus, and dividends.

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 api-carbon-cashmere-de-8cf6186e
```

Example prompt: Show me the top miners on Bittensor subnet 64, ranked by incentive — I want to see their stake, trust, emissions, and whether they have validator permits.

## When to prefer this

Use this endpoint when you need ranked miner performance data for a specific Bittensor subnet by incentive score. Prefer this over a full metagraph snapshot when you only need the competitive leaderboard view rather than all 256-neuron details or subnet-level summary statistics. Ideal for monitoring miner competition, validator concentration, or tracking performance changes on any of the 512 possible subnets.

## Known failure modes

- Invalid netuid (outside 0-511 range) returns a 400 or validation error
- Subnet not yet tracked or with no registered miners may return empty leaderboard array
- Payment failure (x402 protocol) returns 402 if USDC not provided
- Network or node unavailability returns 5xx error
- Rate limiting may occur under high request volume

## How this service works

Top-N miners for ANY tracked Bittensor subnet ranked by incentive. Returns rank, uid, stake, tao_stake, alpha_stake, trust, validator_trust, incentive, emission, consensus, dividends, validator_permit, active, blocks_behind per entry. Pass netuid in path. Operator self-exclusion applied to SN123. AI agent API for cross-subnet miner analytics, validator concentration, and Bittensor network competition.

## Output

A JSON array of miner entries for the specified subnet, each containing rank, uid, stake, tao_stake, alpha_stake, trust, validator_trust, incentive, emission, consensus, dividends, validator_permit, active status, and blocks_behind. Entries are sorted descending by incentive. Operator self-exclusion is applied to SN123.
