# Carbon & Cashmere Kaspa Throughput & DAG-Width Health

> Carbon & Cashmere Kaspa Throughput & DAG-Width Health is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Returns Kaspa blockchain throughput metrics including chain-block rate, estimated total DAG rate, TPS, and multi-month pre-fork baseline comparisons for hardfork impact tracking.

## 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 carbon-cashmere-kaspa-throughput-dag-width-health-bdde4bf3
```

Example prompt: What's Kaspa's current throughput health — give me the live chain-block rate, estimated total DAG rate, and TPS compared to the multi-month pre-fork baseline so I can see the hardfork's impact?

## When to prefer this

Use this endpoint when you need Kaspa-specific network throughput analytics — particularly DAG-width metrics and hardfork baseline comparisons — that generic crypto price APIs do not provide. Prefer this over general blockchain explorers when you need structured, research-grade TPS and DAG rate data with pre/post-fork context.

## Known failure modes

- Payment not received or invalid x402 payment header — returns 402 Payment Required
- Upstream Kaspa node data unavailable — may return 503 or stale data
- Malformed request method (only GET/HEAD/DELETE supported) — returns 405 Method Not Allowed
- Rate limiting or quota exceeded — returns 429 Too Many Requests

## How this service works

Kaspa throughput & DAG-width: chain-block rate, estimated total DAG rate, TPS vs multi-month pre-fork baseline — hardfork impact tracking. Informational research data — not investment advice.

## Output

Returns a JSON object with current Kaspa throughput snapshot (chain-block rate, estimated total DAG rate, current TPS), hourly throughput data arrays, and a 30-day-to-7-day baseline object for pre-fork comparison, enabling hardfork impact analysis.
