# Mangrove Developer – Crypto Smart Money Netflows

> Mangrove Developer – Crypto Smart Money Netflows is a paid API for AI agents from api.mangrovedeveloper.ai, paid per call via x402, $0.02/call, status unknown (last checked 2026-11-04).

Returns net inflow/outflow data for crypto assets tracked by smart-money wallets (Funds and Smart Traders) over a configurable timeframe and chain set.

## 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 mangrove-developer-crypto-smart-money-netflows-9ae01f99
```

Example prompt: Pull the smart money netflows for crypto assets over the last 7 days across Ethereum and Solana, limit to the top 20 results, and include both Fund and Smart Trader wallet labels.

## When to prefer this

Use this endpoint when you need aggregated on-chain net flow data specifically attributed to smart-money wallet categories (Funds, Smart Traders) rather than raw transaction data. Prefer this over generic blockchain explorers when the goal is to understand institutional or informed-investor capital movement across assets and chains in a time-bucketed format.

## Known failure modes

- Invalid or unsupported chain identifier returns an error or empty results
- Unsupported timeframe format causes a 400 bad request
- Exceeding rate limits or missing x402 payment returns a 402 Payment Required
- Empty results if no smart-money activity was recorded in the specified window
- Malformed query parameters (e.g. non-integer limit) return schema validation errors
