# PulseFeed Token Pulse

> PulseFeed Token Pulse is a paid API for AI agents from pulsefeed.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns real-time ERC-20 activity metrics on Base—transfer count, volume, and unique senders/receivers over a recent block window—for any token address.

## 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 pulsefeed-token-pulse-e38e3414 -d '<json body>'
```

Example prompt: Check if the ERC-20 token at 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed is actually active on Base right now — I need the transfer count, total volume, and how many unique senders and receivers it has seen in the last block window.

## When to prefer this

Use this endpoint when you need a quick, no-infrastructure pulse check on whether a specific ERC-20 token on Base is actively being traded or transferred right now, without setting up your own RPC node or blockchain indexer. Ideal for lightweight activity screening, token due diligence, or alerting pipelines where a single call suffices.

## Known failure modes

- Invalid or malformed token address returns an error or empty result
- Token address is on a network other than Base and is not found
- No transfers in the block window may return zero-counts (token appears inactive)
- Service unavailable or payment not accepted returns HTTP 402 or 5xx
- Block window may be stale if called at chain reorganization moments

## How this service works

Is this token active right now? Live pulse of any ERC-20 on Base: transfer count, volume and unique senders/receivers over a recent block window — one call, no RPC or indexer needed. ?token=0x...

## Output

Returns a summary of ERC-20 token activity on Base over a recent block window, including transfer count, transfer volume, number of unique senders, number of unique receivers, and an indication of whether the token is currently active — all without requiring the caller to run an RPC node or indexer.
