# Carbon Cashmere Solana Whale Flow API

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

Returns the last 24 snapshots of on-chain whale movement data for Solana, including SOL moved, exchange inflow/outflow, and largest transactions across 12 tracked whale wallets (Wintermute, Kraken, etc.)

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-157931e0
```

Example prompt: Pull the latest whale flow data for Solana — I want to see how much SOL the tracked wallets like Wintermute and Kraken have moved, whether it's flowing into or out of exchanges, and what the largest transactions look like across the last 24 snapshots.

## When to prefer this

Use this endpoint when you need real-time smart money tracking specifically for Solana — particularly when you want exchange flow direction (accumulation vs. distribution) and named institutional wallet attribution (Wintermute, Kraken, etc.) rather than generic on-chain stats. Prefer this over generic block explorers when you need pre-aggregated whale intelligence with historical 24-snapshot depth ready for agent consumption.

## Known failure modes

- Payment not included or insufficient (402 Payment Required)
- Endpoint temporarily unavailable due to node or data pipeline issues (503)
- Rate limit exceeded (429)
- Malformed request headers (400)
- No snapshots available if data pipeline is lagging (empty snapshots array in response)

## How this service works

Get whale movement data — Solana: 12 tracked whale wallets (Wintermute, Kraken, etc.) with SOL moved, exchange inflow/outflow, and largest transactions. BTC: mempool fee trends, congestion levels, hashrate, and block data. Last 24 snapshots. AI agent API for smart money tracking, whale alert monitoring, and on-chain flow analysis.

## Output

A JSON object with chain='solana', a summary of aggregate whale activity, and an array of up to 24 time-series snapshots each containing SOL moved by tracked wallets, exchange inflow/outflow volumes, and the largest individual transactions detected on-chain.
