## How to call it through Zero

```sh
zero fetch --capability api-carbon-cashmere-de-db5e944b
```

Example prompt: Pull the latest alpha-token prices in both TAO and USD for all 129 Bittensor subnets — I want to see which subnets have the cheapest and most expensive alpha tokens right now for a dTAO rebalancing decision.

## When to prefer this

Use this endpoint when you need a full snapshot of alpha-token prices across all Bittensor subnets in a single call, especially for portfolio rebalancing, arbitrage screening, or building dashboards. Prefer this over per-subnet queries when you need all 129 subnets at once.

## Known failure modes

- Upstream Subtensor node unavailable — returns 5xx error
- Stale data if node is syncing — prices may lag by a few blocks
- Rate limiting if called too frequently without payment
- Partial subnet coverage if new subnets were recently registered and not yet indexed

## How this service works

Latest alpha-token price per Bittensor subnet (TAO + USD). All 129 subnets in one call. AI agent API for cross-subnet price arbitrage, dTAO portfolio rebalancing. Informational research data — not investment advice.

## Output

A list of all 129 Bittensor subnets, each with the current alpha-token price expressed in TAO and USD. Useful for cross-subnet price comparison, arbitrage analysis, and portfolio rebalancing of dTAO holdings.
