# Carbon Cashmere Coin Network Stats API

> Carbon Cashmere Coin Network Stats API is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns coin-specific L1 network health metrics for select cryptocurrencies including TAO, KAS, XLM, ALGO, and QUBIC — covering stake ratios, hashrate, DAG tips, ledger stats, tick/epoch data, and more.

## Facts

- Endpoint: GET https://api.carbon-cashmere.de/v1/network/:coin
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/api-carbon-cashmere-de-d3f8698a

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-d3f8698a
```

Example prompt: What are the current network stats for TAO — things like block number, peer count, whether it's syncing, and total stake in TAO?

## When to prefer this

Choose this endpoint when you need coin-specific L1 network fundamentals for TAO, KAS, XLM, ALGO, or QUBIC — especially Bittensor stake ratio, Kaspa hashrate/DAG state, or QUBIC epoch/tick. It is distinct from price feeds or trading signals and is ideal for fundamental network health monitoring, not market data.

## Known failure modes

- Unsupported coin ticker returns error — only TAO, KAS, XLM, ALGO, QUBIC have network-specific metrics
- Missing or malformed coin path param causes 400 bad request
- Payment failure via x402 protocol returns 402 with payment details
- Stale data if upstream node is behind — check updated_at timestamp
- Non-uppercase ticker symbol may not match enum validation

## How this service works

Get coin-specific network stats — TAO (Bittensor subnet data, stake ratio), KAS (hashrate, DAG tips, difficulty), XLM (ledger stats, tx counts), ALGO (round, protocol), QUBIC (tick, epoch). AI agent API for L1 network health monitoring and fundamental analysis.

## Output

Returns a JSON object with the coin ticker, data source, an updated_at timestamp, and a metrics object containing coin-specific network health fields — e.g. for TAO: block_number, peers, is_syncing, total_stake_tao, token_symbol, token_decimals; for KAS: hashrate, DAG tips, difficulty; for XLM: ledger stats, tx counts; for ALGO: round, protocol version; for QUBIC: tick, epoch.

## Example request

```json
{
 "input": {
  "type": "http",
  "method": "GET",
  "queryParams": {
   "coin": "TAO"
  }
 }
}
```
