# Carbon & Cashmere Bittensor Alpha Token Price History

> Carbon & Cashmere Bittensor Alpha Token Price History is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Returns a time-series of alpha-token prices for a specified Bittensor subnet over configurable windows (1h, 24h, 7d, 30d), sampled every 10 minutes.

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 carbon-cashmere-bittensor-alpha-token-price-history-bb1d2f27
```

Example prompt: Can you pull the alpha token price history for Bittensor subnet 64 over the last 24 hours so I can see how it's been trending?

## When to prefer this

Choose this endpoint when you need historical alpha-token price data for a specific Bittensor subnet at 10-minute granularity. It is ideal for building trading signals, trend analysis, or research into subnet-level token dynamics on the Bittensor network. Prefer it over generic crypto price APIs when you specifically need Bittensor alpha-token data with subnet-level granularity.

## Known failure modes

- Invalid netuid format (not 0-511 integer) returns a 400 validation error
- Subnet UID does not exist on the Bittensor network returns empty data or 404
- Payment not provided or insufficient USDC triggers 402 Payment Required
- No price data available for the requested time window returns empty array
- Rate limiting or server overload returns 429 or 503

## How this service works

Time-series of alpha-token price for a single Bittensor subnet (window: 1h/24h/7d/30d). Sourced from bittensor_alpha_prices captured every 10 minutes. AI agent API for alpha-token trading signals. Informational research data — not investment advice.

## Output

A time-series array of alpha-token price data points for the specified Bittensor subnet, sampled every 10 minutes, covering the requested window (1h, 24h, 7d, or 30d). Each data point includes a timestamp and price value. Useful for trend analysis, signal generation, or research into subnet token performance.
