```sh
zero fetch --capability ragradar-multi-chain-heatmap-415cf09b
```

Example prompt: Show me the on-chain activity heatmap for Solana right now — I want to see where transaction density is concentrated across the network.

## When to prefer this

Use this endpoint when you need a bird's-eye view of activity concentration on Base, Arbitrum, or Solana — useful for identifying hot spots in DeFi activity, transaction density, or liquidity clustering before doing deeper analysis with other RagRadar endpoints.

## Known failure modes

- Invalid or unsupported chain name returns error
- Payment not included or insufficient USDC results in 402 Payment Required
- Chain parameter missing from URL path returns 400 or 404
- Upstream blockchain data unavailable causes 503 or timeout
- Malformed chain identifier returns validation error
