## 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 bittensor-dtao-subnet-overview-7ea7278a
```

Example prompt: Can you pull up an overview of all active Bittensor dTAO subnets right now, including their alpha prices, TAO liquidity, and market caps? Show me up to 100 subnets on the first page.

## When to prefer this

Choose this endpoint when you need a broad overview of ALL active Bittensor dTAO subnets in a single paginated call, rather than drilling into a single subnet by netuid. It is ideal for dashboards, market-cap rankings, liquidity comparisons, or any workflow that needs to enumerate the full subnet registry with pool metrics.

## Known failure modes

- Missing or invalid TAOSTATS_API_KEY returns authentication error
- Invalid page or limit values (e.g. limit > 200) return validation error
- TaoStats upstream unavailability causes timeout or 503
- Empty result set if no subnets are registered on-chain
- Rate limiting if too many requests are made rapidly

## How this service works

Overview of all active Bittensor dynamic TAO (dTAO) subnets with key pool metrics: netuid, symbol, alpha price, TAO liquidity, total alpha issuance, and market cap. Count matches on-chain subnets. Requires TAOSTATS_API_KEY.

## Output

A paginated list of all on-chain Bittensor dTAO subnets, each with its netuid identifier, token symbol, current alpha price in TAO, TAO liquidity in the pool, total alpha tokens issued, and market capitalization. The count matches the number of active on-chain subnets.
