# Bittensor Subtensor Network Status

> Bittensor Subtensor Network Status is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Returns live Bittensor subtensor chain status from a self-hosted lite node, including block height, finalized block, peer count, sync state, total subnets, and node version.

## Facts

- Endpoint: GET https://api.carbon-cashmere.de/v1/subtensor/network
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/api-carbon-cashmere-de-1478ded0
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_cK3QI239_q2kWvISedRXE

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-1478ded0
```

Example prompt: What's the current Bittensor subtensor chain status — block height, finalized block, peer count, and whether the node is syncing?

## When to prefer this

Use this endpoint when you need real-time Bittensor subtensor chain health data from a self-operated lite node rather than a third-party RPC, especially for monitoring sync state, block progress, and peer connectivity. Prefer this over general blockchain explorers when you need low-latency, programmatic status checks for automated Bittensor infrastructure analysis or AI agent workflows.

## Known failure modes

- Node temporarily unreachable or restarting — may return 5xx error
- Node is behind or syncing — is_syncing=true indicates chain data may be stale
- Rate limiting or payment failure — 402 payment required if x402 header not provided
- Unexpected chain fork or reorganization may cause block_number to lag finalized_block significantly

## How this service works

Professional crypto market intelligence. Real-time prices, signals, and market scoring.

## Output

Returns a JSON object with timestamp, source identifier ('own_subtensor_lite_node'), block_number (current chain tip), finalized_block, peer_count (integer), is_syncing (boolean), total_subnets (integer), and node_version string. Example: block_number=2585476, finalized_block=2585088, peer_count=18, is_syncing=false, node_version='4.0.0-dev-unknown'.
