# Kaspa Mining Economics API

> Kaspa Mining Economics API is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Returns live Kaspa (KAS) mining economics including revenue per TH/s/day in KAS and USD, block subsidy, DAG-aware emission rate, and electricity cost breakeven model

## 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 kaspa-mining-economics-api-c6c6180d
```

Example prompt: What are the current Kaspa mining economics — specifically revenue per TH/s per day in both KAS and USD, the live block subsidy, and the breakeven electricity price — assuming my electricity costs $0.06 per kWh?

## When to prefer this

Choose this endpoint when you need live, node-sourced Kaspa mining profitability data with a configurable electricity cost model — specifically when you want DAG-aware emission rates and coinbase-payload-measured block subsidies rather than estimated or third-party aggregated figures. Prefer this over generic crypto mining calculators when Kaspa-specific accuracy and real-time archival node data matter.

## Known failure modes

- electricity_cost_kwh outside 0-1 range returns 400 validation error
- Node sync lag may return stale data indicated in freshness object
- Payment not received returns 402 Payment Required
- Service unavailable returns 503 if archival node is unreachable

## How this service works

Kaspa mining economics from our own archival node: KAS + USD revenue per TH/s/day, block subsidy measured live from coinbase payloads, DAG-aware emission rate, electricity-cost model with profit margin and breakeven price. Informational research data — not investment advice.

## Output

Returns a JSON object with network state (hashrate, difficulty), block reward details sourced live from coinbase payloads, miner economics per TH/s (KAS/day, USD/day, profit margin), breakeven electricity price in USD/kWh, and freshness metadata indicating when the data was last updated from the archival node.
