## 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 market-intelligence-api-token-traders-top-buyers-sellers-b332f618
```

Example prompt: Who are the top 20 buyers and sellers of the token at 0x940181a94a35a4569e4529a3cdfb74e38fd98631 on Base in the last hour — show me their net USD flow and whether any are smart money wallets?

## When to prefer this

Choose this endpoint when you need wallet-level granularity on who is actively buying or selling a specific ERC-20 token right now, especially when you want smart-money classification and bot detection built in. It is ideal for real-time trade-flow surveillance, detecting accumulation or distribution by profitable wallets, and filtering out bot noise — all in a single call. Prefer it over generic DEX analytics tools when you need per-wallet PnL labels rather than just aggregate volume.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Unsupported chain value returns a validation error
- Token has no trades in the last hour, returning empty buyer/seller lists
- Payment not completed (x402) results in 402 Payment Required response
- Limit parameter out of range (below 1 or above 50) returns a validation error
- Network timeouts or RPC issues for the specified chain may cause delays or errors

## How this service works

Who bought and who sold this token ($0.01): top buyers and sellers of any ERC-20 in the last hour on Base, Ethereum, Arbitrum, Optimism or Polygon, each the wallet that signed the swap, with net USD, buys and sells, a label from tracked PnL (SMART_MONEY, PROFITABLE, UNTRACKED), a bot flag, unique wallets and smart-money net flow. Use to see which wallets drive a token.

## Output

A structured JSON response listing top buyer and seller wallets for the specified ERC-20 token, each entry containing the wallet address, net USD flow, number of buy and sell transactions, a classification label (SMART_MONEY, PROFITABLE, or UNTRACKED), a bot flag, plus aggregate metrics including unique wallet count and smart-money net flow for the last hour.
