## 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-c662dc77
```

Example prompt: Can you pull the blockchain activity heatmap for Ethereum so I can see when transaction volume peaks throughout the day?

## When to prefer this

Use this endpoint when you need time-series heatmap data of blockchain activity for a specific chain — particularly useful for timing transactions around low-gas windows, identifying peak DeFi activity periods, or building dashboards that visualize on-chain congestion patterns. Prefer this over generic block explorers when you need structured, analytics-ready heatmap output consumable by an agent.

## Known failure modes

- Unsupported or misspelled chain identifier returns an error or empty data
- Payment not completed via x402 protocol results in 402 Payment Required response
- Chain parameter missing from path returns 400 Bad Request
- Network downtime on vercel.app hosting causes 503 or timeout
- Rate limiting or quota exhaustion may result in 429 Too Many Requests
