## 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-e4713d4c
```

Example prompt: Pull the full on-chain bundle from Carbon Cashmere — I want all five analytics at once: Bitcoin whale activity, fee market, RBF pulse, plus Kaspa block propagation and mining economics, all from their own nodes.

## When to prefer this

Choose this endpoint when you need all 5 on-chain analytics (BTC whale stream, BTC fee-market, BTC RBF-pulse, Kaspa block-propagation, Kaspa mining-economics) and want to minimize cost (17% bundle discount) and latency vs. making 5 separate calls. Ideal for research dashboards, automated monitoring agents, or any workflow that consumes multiple L1 metrics simultaneously. Prefer this over individual endpoints when you need the full picture of both Bitcoin and Kaspa network conditions in a single round-trip.

## Known failure modes

- Payment failure (x402): insufficient USDC balance or invalid payment header returns 402
- Node sync lag: if the proprietary node is behind the chain tip, data may be slightly stale
- Rate limiting: excessive calls may result in 429 throttling
- Partial data: one of the 5 sub-analytics fails while others succeed, potentially returning incomplete bundle
- Network timeout: slow node response causes request timeout

## How this service works

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

## Output

A single JSON response containing all 5 node-backed L1 analytics: BTC whale movements from ZMQ stream, BTC fee-market metrics, BTC RBF-pulse indicators, Kaspa block-propagation stats, and Kaspa mining-economics data. Sourced directly from proprietary Bitcoin Core and Rusty-Kaspa nodes with no third-party intermediaries. Costs $0.40 USDC per call (17% discount vs. buying each of the 5 endpoints separately at $0.48 total).
