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-blockchain-heatmap-api-c92caf6c
```

Example prompt: Show me a heatmap of on-chain activity for Ethereum right now — I want to see where transaction density is clustering across the network.

## When to prefer this

Use this endpoint when you need a visual or structured representation of transaction or activity density on a specific blockchain, particularly for identifying hot zones, peak activity windows, or network congestion patterns. Prefer this over raw transaction list endpoints when the goal is pattern recognition or aggregated activity analysis.

## Known failure modes

- Unsupported or misspelled chain identifier returns an error or empty result
- Missing chain path parameter causes a 400 or 404 error
- Payment not fulfilled via x402 protocol results in a 402 Payment Required response
- Upstream data source unavailability causes 500 or timeout errors
- Rate limiting if multiple rapid calls are made without payment
