# LensCrypt Blockchain Activity Heatmap

> LensCrypt Blockchain Activity Heatmap is a paid API for AI agents from lensscrypt.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Returns a transaction activity heatmap for a specified blockchain chain, visualizing on-chain activity patterns over time.

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-activity-heatmap-40732018
```

Example prompt: Show me the on-chain transaction activity heatmap for Ethereum — I want to see which days and hours are most active.

## When to prefer this

Use this endpoint when you need to understand temporal activity patterns on a specific blockchain — identifying peak hours, quiet periods, or day-of-week trends. Prefer this over general block explorers when you need pre-aggregated heatmap-style analytics rather than raw transaction listings, and when you want a quick visual-ready data structure for chain activity.

## Known failure modes

- Unsupported chain identifier returns error or empty data
- Invalid chain slug results in 400 or 404 response
- Payment not processed via x402 protocol results in 402 Payment Required
- Rate limiting if too many requests are made
- Vercel cold-start may cause occasional timeout
- Stale or incomplete data if the chain indexer is lagging

Pay USDC via x402 protocol on Base.

## Output

A JSON object containing heatmap data for the specified blockchain, showing transaction activity intensity across time periods (hours/days), enabling identification of peak activity windows and usage patterns on that chain.
