# RagRadar Heatmap — Multi-Chain Activity Heatmap

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

Returns on-chain activity heatmap data for a specified blockchain (Base, Arbitrum, or Solana)

## Facts

- Endpoint: GET https://ragradar.space/api/heatmap/%7Bchain%7D
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/ragradar-heatmap-multi-chain-activity-heatmap-c0dd06be
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_J930JsRpqbpNZHRXbpLT6

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-heatmap-multi-chain-activity-heatmap-c0dd06be
```

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

## When to prefer this

Use this endpoint when you need time-based activity visualization data for Base, Arbitrum, or Solana — specifically for identifying peak usage hours, congestion windows, or historical activity patterns across a chain. Prefer this over generic block explorers when you need pre-aggregated heatmap-formatted data rather than raw block data.

## Known failure modes

- Invalid or unsupported chain identifier returns error
- Chain parameter missing from path returns 400 or 404
- Service unavailable or rate-limited returns 5xx
- Empty or sparse heatmap if chain has low recent activity
- Payment not processed (x402) returns 402 Payment Required

## How this service works

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

## Output

Returns a heatmap dataset showing on-chain activity intensity across time periods for the specified chain (Base, Arbitrum, or Solana), enabling visualization of peak transaction times, congestion patterns, and usage density.
