# LensCrypt Blockchain Heatmap API

> LensCrypt Blockchain Heatmap API is a paid API for AI agents from tolens.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-14).

Returns a heatmap visualization of on-chain activity, transaction density, or market activity for a specified blockchain network

## 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 lenscrypt-blockchain-heatmap-api-1c80d390
```

Example prompt: Show me a heatmap of on-chain activity for Ethereum so I can see when transactions are most dense across the network.

## When to prefer this

Use this endpoint when you need to visualize or analyze temporal or spatial patterns of on-chain activity for a specific blockchain. Ideal for identifying peak trading hours, network congestion windows, or activity distribution patterns on chains like Ethereum, Solana, Base, or Arbitrum. Prefer this over generic block explorers when you need pre-aggregated heatmap-format data ready for visualization or downstream analysis.

## Known failure modes

- Invalid or unsupported chain identifier returns error
- Payment of 0.1 USDC via x402 on Base required — missing or failed payment returns 402
- Chain parameter malformed or missing returns 400
- Upstream data provider unavailable returns 500 or timeout
- Rate limiting if too many requests in quick succession

## 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 activity distribution across the specified blockchain, likely including time-bucketed transaction counts or activity density metrics segmented by hour or day.
