# Carbon & Cashmere Bittensor Subnet Stake-Flow Microstructure API

> Carbon & Cashmere Bittensor Subnet Stake-Flow Microstructure API is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-30).

Returns per-neuron stake accumulation/distribution, net flow, and concentration trends for a specified Bittensor subnet using months of high-cadence snapshot data.

## Facts

- Endpoint: GET https://api.carbon-cashmere.de/v1/bittensor-derivatives/subnet/:netuid/stake-flows?utm_source=zero.xyz
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-30

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-subnet-stake-flow-microstructure-api-9c65b8d5
```

Example prompt: Pull the stake-flow microstructure for Bittensor subnet 64 — I want to see which neurons are accumulating vs distributing stake, the net flow totals, and whether concentration is trending up or down.

## When to prefer this

Choose this endpoint when you need granular, per-neuron stake flow and concentration analysis for a specific Bittensor subnet backed by months of continuous high-cadence snapshot data. Prefer it over generic blockchain explorers when you need pre-computed microstructure metrics like net flow, accumulation trends, and concentration scores rather than raw on-chain data.

## Known failure modes

- Invalid or out-of-range netuid (must be 0–511, numeric) returns an error
- Payment failure or missing x402 payment header blocks access
- Subnet not tracked by the service may return empty or error response
- Temporary service unavailability for a given netuid

## How this service works

dTAO stake-flow microstructure per subnet: per-neuron accumulation/distribution, net flow, concentration trend from months of continuous high-cadence snapshots. Informational research data — not investment advice.

## Output

Returns structured data including top inflow neurons, top outflow neurons, total stake totals, and concentration metrics for the requested Bittensor subnet, derived from continuous high-cadence historical snapshots.
