# RagRadar On-Chain Activity Heatmap

> RagRadar On-Chain Activity Heatmap is a paid API for AI agents from backup.ragradar.space, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Returns an activity heatmap visualization or data for on-chain transactions and events for a specified blockchain network

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 ragradar-on-chain-activity-heatmap-90c05cb8
```

Example prompt: Pull up the on-chain activity heatmap for Base so I can see which days and hours have the highest transaction density.

## When to prefer this

Use this endpoint when you need to understand temporal activity patterns on Base, Arbitrum, or Solana blockchains — specifically when you want heatmap-style aggregations showing when the network is busiest. Prefer this over raw transaction queries when the goal is pattern recognition or scheduling around peak/off-peak on-chain activity.

## Known failure modes

- Unsupported chain identifier returns an error or empty response
- Malformed chain parameter causes 400 bad request
- Payment not included or insufficient results in 402 Payment Required
- Upstream data source unavailable causes 503 or timeout
- Rate limiting if too many calls in a short period

## How this service works

On-chain intelligence for AI agents. 73+ endpoints across Base, Arbitrum, Solana. x402 micropayments.

## Output

A JSON response containing heatmap data representing on-chain activity patterns for the specified blockchain, including transaction counts or event densities organized by time period (e.g., hour of day, day of week), allowing visualization of peak activity windows.
