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 lenscrypt-chain-heatmap-4531beeb
```

Example prompt: Show me the on-chain activity heatmap for Ethereum — I want to see where the hottest transaction clusters are across the network.

## When to prefer this

Use this endpoint when you need a visual or data-driven representation of on-chain activity density for a specific blockchain, particularly when identifying hot zones, peak activity periods, or network usage patterns. Prefer this over raw transaction queries when you want an aggregated, pre-processed heatmap view rather than individual transaction data.

## Known failure modes

- Unsupported or misspelled chain identifier returns an error or empty result
- Payment of 0.1 USDC via x402 on Base fails or is rejected, blocking the request
- Rate limiting if too many requests are made in quick succession
- Chain parameter not URL-encoded correctly leading to 404
- Upstream data source unavailable causing stale or null heatmap data

## How this service works

81 paid REST endpoints covering wallet analytics, DeFi yields, token safety, smart money tracking, whale alerts, sniper detection, GMX perps, Solana tools, protocol stats, gas tracking, DEX quotes, NFT analytics, social signals, and 8 AI-powered endpoints (MiMo V2.5). Pay USDC via x402 protocol on Base.

## Output

Returns a JSON object containing heatmap data representing on-chain activity distribution or intensity metrics for the specified blockchain chain, likely organized by time periods or address clusters.
