> PulseFeed Smart-Money Flow Signal is a paid API for AI agents from pulsefeed.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Returns net accumulation/distribution flow per address for a Base ERC-20 token, with a decision-ready signal indicating whether smart money is currently buying or selling.

## 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-smart-money-flow-signal-1ac055ce -d '<json body>'
```

Example prompt: Can you check if smart money is currently accumulating or distributing the token at 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed on Base — I want the net position change per address and the overall accumulation/distribution signal.

## When to prefer this

Use this endpoint when you need a decision-ready accumulation/distribution signal derived from on-chain Base ERC-20 flows — specifically when you want to know if smart money wallets are net increasing or decreasing positions, not just raw transfer volume. Prefer this over whale alert endpoints when you need an aggregated directional signal rather than individual large transaction alerts.

## Known failure modes

- Invalid or non-ERC-20 contract address returns an error or empty result
- Token with no recent activity on Base may return neutral/flat signal
- Payment of 0.02 USDC not received or x402 flow fails — returns 402 Payment Required
- Token not deployed on Base (wrong chain) returns no data
- Rate limiting or node connectivity issues may cause transient failures

## How this service works

Who is accumulating or dumping this token right now? Smart-money flow on Base: net position change per address over a block window plus a decision-ready accumulation/distribution signal. ?token=0x...

## Output

Returns net position change per wallet address for the queried ERC-20 on Base, along with a consolidated accumulation/distribution signal indicating whether smart money is net buying (accumulating) or net selling (distributing) the token in the current window.
