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 subtensor-tao-transfer-history-2bbe62e9
```

Example prompt: Pull the last 50 TAO transfers on Subtensor and filter them to just the address 5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY so I can see recent activity on that wallet.

## When to prefer this

Use this endpoint when you need on-chain TAO transfer data from the Subtensor network — particularly for wallet activity monitoring, transaction auditing, or building transfer history for a specific address. It is the right choice over general crypto APIs when the target is specifically Bittensor/Subtensor TAO transfers with SS58 address filtering, fee data, and block-level granularity.

## Known failure modes

- Missing or invalid TAOSTATS_API_KEY returns an authentication error
- Invalid SS58 address format causes a filter failure or empty result set
- Requested page number beyond available data returns an empty list
- limit exceeding 100 is rejected with a validation error
- Downstream TaoStats API unavailability causes timeout or 503 response

## How this service works

Recent TAO token transfers on Subtensor with transfer volume in TAO, from/to addresses, transaction hashes, fees, and block numbers. Requires TAOSTATS_API_KEY.

## Output

Returns a paginated list of recent TAO token transfers on the Subtensor blockchain. Each record includes the transfer amount in TAO, sender and receiver SS58 addresses, transaction hash, transaction fee, and the block number in which the transfer was confirmed.
