## How to call it through Zero

```sh
zero fetch --capability api-carbon-cashmere-de-754538c8
```

Example prompt: Can you pull the latest hourly EVM call counts for TaoEVM on Bittensor so I can see how dApp adoption is trending over the past day?

## When to prefer this

Use this endpoint when you need granular hourly EVM call volume specifically for the TaoEVM (EVM-on-Bittensor) network, as opposed to general Ethereum or other EVM chain activity. Ideal for analysts tracking cross-VM adoption trends, dApp growth on Bittensor, or building time-series dashboards for Subtensor EVM usage.

## Known failure modes

- No data available yet for the requested time window — returns empty hourly array
- Upstream Subtensor node lag causes stale or delayed hourly counts
- Rate limiting or payment failure returns 402/429 with no data
- Malformed response if the TaoEVM node is temporarily unreachable

## How this service works

EVM-on-Bittensor Ethereum.Executed call count per hour. Tracks TaoEVM dApp adoption. AI agent API for cross-VM adoption analysts. Informational research data — not investment advice.

## Output

A JSON array of hourly buckets, each containing an ISO 8601 timestamp and the number of EVM calls executed on the TaoEVM (EVM-on-Bittensor) network during that hour, covering the most recent ~24 hours of activity.
