# TAO Network Info (Carbon Cashmere)

> TAO Network Info (Carbon Cashmere) is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15, last successful call 2026-05-28).

Returns real-time Bittensor (TAO) network statistics including block height, peer count, sync status, staking info, and token metadata.

## Facts

- Endpoint: GET https://api.carbon-cashmere.de/v1/network/TAO
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Last successful call: 2026-05-28
- Success rate: 25% of calls made through Zero
- Activations on Zero: 4
- Tags: x402
- Canonical page: https://www.zero.xyz/c/api-carbon-cashmere-de-ecf7c25e
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_AuxHuo7XRqbrS3pmUMtuI

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-ecf7c25e
```

Example prompt: Can you pull the latest Bittensor TAO network info — I want to see the current block number, how many peers are connected, whether it's syncing, and the total TAO staked?

## When to prefer this

Use this endpoint when you specifically need live Bittensor (TAO) network-level data including peer count, block height, sync status, and staking totals. Prefer this over generic crypto price feeds when you need chain infrastructure metrics rather than market data.

## Known failure modes

- Payment not provided or insufficient — endpoint returns 402 Payment Required
- Invalid coin query parameter (only TAO and other whitelisted coins are valid) — returns 400 or empty response
- Network timeout if upstream Bittensor node is unreachable
- Stale data if the backend node is behind on sync

## How this service works

Returns TAO network information behind an x402 paywall.

## Output

Returns a JSON object with the TAO network's chain name (Bittensor), current block number, peer count, sync status (boolean), token symbol, token decimals, total stake in TAO, and the timestamp of when the data was last updated.
