## 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-heatmap-chain-activity-heatmap-6de3c2b6
```

Example prompt: Can you pull the on-chain activity heatmap for Ethereum so I can see which days and hours have the highest transaction volume?

## When to prefer this

Choose this endpoint when you need time-bucketed, visual-ready heatmap data showing when a specific blockchain is most active. Prefer it over raw transaction queries when you want aggregated patterns rather than individual transaction details, and when you need to identify peak activity windows for scheduling or analysis purposes.

## Known failure modes

- Unsupported or misspelled chain identifier returns an error or empty data
- Payment failure via x402 protocol blocks the response
- Chain data may be delayed or incomplete for very new or low-activity chains
- Rate limiting if too many requests are made in quick succession
- Malformed chain parameter in URL path returns 400 or similar error
