## Free sample

See an answer for the demo input first, free (no payment, 10 a minute): [https://aayatai.com/sample/pool-depth](/sample/pool-depth). It is a stored real answer when we have one, otherwise an example marked `"kind": "illustrative"`.

```bash
curl "https://aayatai.com/sample/pool-depth"
```

## 1. See the price (free)

Call it without paying: you get `402 Payment Required` and a `PAYMENT-REQUIRED` header with the exact price and where to pay.

```bash
curl -i "https://aayatai.com/pool/depth?address=0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed&chain=base&amountUsd=5000"
```

## 2. Pay and call (TypeScript)

```bash
npm install @x402/fetch @x402/evm viem
```

```ts
import { wrapFetchWithPaymentFromConfig } from "@x402/fetch";
import { ExactEvmScheme } from "@x402/evm";
import { privateKeyToAccount } from "viem/accounts";

// A wallet used only by your agent, holding a little USDC on Base.
const account = privateKeyToAccount(process.env.WALLET_PRIVATE_KEY as `0x${string}`);
const pay = wrapFetchWithPaymentFromConfig(fetch, {
  schemes: [{ network: "eip155:8453", client: new ExactEvmScheme(account) }],
});

const res = await pay("https://aayatai.com/pool/depth?address=0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed&chain=base&amountUsd=5000");
console.log(await res.json());
```

## 3. Or as an MCP tool

```ts
// MCP server: https://aayatai.com/mcp (Streamable HTTP). With the x402 MCP client (see /start):
const result = await client.callTool("pool-depth", {"address":"0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed","chain":"base","amountUsd":5000});
```

## Inputs

- `amountUsd` (number; default `1000`): Trade size in USD.
