## 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 base-token-on-chain-pulse-b0d9b178
```

Example prompt: What's the on-chain pulse for token 0xabc...123 on Base — give me the transfer volume, unique addresses, and whether it's alive over the last 100 blocks.

## When to prefer this

Use this endpoint when you need real-time, block-level on-chain activity metrics for a specific token on the Base network — especially liveness checks, transfer volumes, and unique address counts. Prefer this over off-chain or CEX-based analytics when you need raw blockchain data. Pair with the momentum or whale-alert sibling endpoints for richer signal.

## Known failure modes

- Invalid or unrecognized token address returns an error
- Token has no activity in the specified block window, returning zero/empty metrics
- Block window parameter out of range or malformed
- Network connectivity issues to Base RPC
- Payment not processed (x402 payment required before data is returned)
