# Kaspa Network Health Analytics

> Kaspa Network Health Analytics is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.03/call, status down (last checked 2026-09-14).

Returns Kaspa blockchain node health metrics including block-rate, DAA score, tip-parallelism, mempool utilization, peer count, and sync uptime over a configurable time window.

## Facts

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-60f53b6e
```

Example prompt: Can you pull the Kaspa network health analytics from the carbon-cashmere full node for the last 24 hours — I want to see block rate vs the 10 bps target, DAA score, tip-parallelism, and mempool utilization?

## When to prefer this

Use this endpoint when you need live, node-backed Kaspa network health data specifically — block-rate relative to the 10 bps target, DAG structure via tip-parallelism, or mempool/peer health — as opposed to price or trading data. Ideal for researchers or agents monitoring Kaspa network performance over time windows up to 168 hours.

## Known failure modes

- Node temporarily out of sync — returns stale or partial data
- Invalid time window parameter (outside 1-168h range) — likely 400 error
- Node connectivity issue — service unavailable or 503
- Payment not processed — 402 response if x402 payment fails
- Rate limiting if too many requests in quick succession

## How this service works

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

## Output

Returns Kaspa network health metrics from a live Rusty-Kaspa full node including blocks/sec and % of 10 bps target, DAA score advancement, tip-parallelism (concurrent chain-tips reflecting DAG structure), mempool utilization, peer-count stability, and sync uptime over the requested time window (1–168 hours).
