# Make x402 Payments

> Use the x402 client SDK to access payment-protected resources on Abstract.

This guide walks through building a client that can automatically pay for x402-protected resources on Abstract.

<Accordion title="Prerequisites">
  * A wallet with USDC on Abstract mainnet or testnet
  * Node.js 18+, Go 1.21+, or Python 3.10+
</Accordion>

## 1. Install the client SDK

<Tabs>
  <Tab title="Fetch">
    ```bash theme={null}
    npm install @x402/fetch @x402/core @x402/evm viem
    ```
  </Tab>

  <Tab title="Axios">
    ```bash theme={null}
    npm install @x402/axios @x402/core @x402/evm viem axios
    ```
  </Tab>

  <Tab title="Go">
    ```bash theme={null}
    go get github.com/coinbase/x402/go
    ```
  </Tab>

  <Tab title="Python">
    ```bash theme={null}
    pip install "x402[httpx]"
    ```
  </Tab>
</Tabs>

## 2. Create a signer

```typescript theme={null}
import { privateKeyToAccount } from "viem/accounts";

const signer = privateKeyToAccount(
  process.env.PRIVATE_KEY as `0x${string}`
);
```

## 3. Wrap your HTTP client

```typescript theme={null}
import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { ExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const signer = privateKeyToAccount(
  process.env.PRIVATE_KEY as `0x${string}`
);

const client = new x402Client();
client.register("eip155:*", new ExactEvmScheme(signer));

const fetchWithPayment = wrapFetchWithPayment(fetch, client);

const response = await fetchWithPayment(
  "https://api.example.com/weather",
  { method: "GET" },
);

const data = await response.json();
console.log(data);
```

## 4. Agent runtime notes

For an automated agent:

* keep the signer scoped to the smallest viable balance
* separate read-only and paid-request workflows
* log payment receipts so you can reconcile usage later

## Next

* Continue to [`AGW CLI`](/ai-agents/wallet-access/agw-cli-overview) if the agent should use AGW instead of a raw private key
* Compare with [`MPP`](/ai-agents/payments/mpp/overview) if your client will make repeated paid requests
