# Kaspa Network Historical Timeseries API

> Kaspa Network Historical Timeseries 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 2026-10-30).

Returns server-side aggregated historical timeseries data (up to 1000 points) for Kaspa blockchain metrics such as hashrate, difficulty, DAG block rate, mempool depth, circulating supply, and more.

## 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-network-historical-timeseries-api-d0d637e5
```

Example prompt: Pull me the daily Kaspa hashrate from January 1 2024 to June 30 2024 using 1-day intervals so I can chart how mining power has changed over that period.

## When to prefer this

Choose this endpoint when you need pre-aggregated historical Kaspa blockchain network metrics (hashrate, difficulty, block rate, mempool, supply, etc.) as a clean timeseries without running your own node. It is especially useful for research, charting, and trend analysis where you need up to 1000 evenly-spaced data points across a custom date range and interval. Prefer it over raw Kaspa APIs when you want server-side aggregation and consistent formatting.

## Known failure modes

- Missing required parameters (metric, from, to) returns a validation error
- Requesting peer_count for dates after 2026-08-10 may return nulls or empty data (data collection ended)
- Date ranges that would produce more than 1000 points at fine granularity may be truncated or require a coarser interval
- Invalid metric enum value returns an error
- from datetime after to datetime returns an error
- Payment failure (x402) results in 402 response without data

## How this service works

Historical Kaspa network metrics as server-side aggregated timeseries (max 1000 points): hashrate, difficulty, DAG block rate, mempool depth, DAA score, tip count, circulating supply, percent mined; peer count only until 2026-08-10. Collected continuously by our own infrastructure (own Kaspa node until 2026-08-10, since then snapshots of the public api.kaspa.org). Informational research data — not investment advice.

## Output

A JSON object containing the requested metric name, unit, interval, an array of timestamped data points (each with a 'ts' ISO datetime and 'value' that may be null for gaps), plus coverage and freshness metadata. Up to 1000 points are returned per call.
