# Bitcoin Node Peer Network Diversity & Privacy Share

> Bitcoin Node Peer Network Diversity & Privacy Share 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 real-time peer distribution across IPv4, IPv6, Tor, I2P, and CJDNS for a self-hosted Bitcoin full node, plus a privacy share percentage.

## Facts

- Endpoint: GET https://api.carbon-cashmere.de/v1/btc-derivatives/diversity
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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-f20f4e3f
```

Example prompt: Can you check the current peer network diversity for that Bitcoin full node — I want to know the breakdown of IPv4, IPv6, Tor, I2P, and CJDNS connections, and what percentage of peers are privacy-preserving?

## When to prefer this

Use this endpoint when you need real-time, node-level peer transport diversity data from an actual running Bitcoin full node — especially for privacy research, network health monitoring, or assessing the proportion of anonymity-network peers (Tor, I2P, CJDNS). Prefer this over blockchain explorers or third-party aggregators when ground-truth, own-node data is required.

## Known failure modes

- Node temporarily unreachable — may return empty or stale data
- All peers zero if node is still syncing or disconnected
- Privacy share 0% if no Tor/I2P/CJDNS peers are connected at query time
- Rate limiting or payment failure via x402 protocol

## How this service works

Bitcoin own-node peer-network diversity (IPv4/IPv6/Tor/I2P/CJDNS distribution) + privacy share. AI agent API for privacy researchers, node-operator tooling, network-health analytics. Informational research data — not investment advice.

## Output

A JSON object containing a timestamp, inbound and outbound peer counts, per-network breakdown (IPv4, IPv6, I2P, onion/Tor, CJDNS), total peer count, and a privacy_share_pct indicating what fraction of peers use privacy-preserving transports.
