url = "https://api.pumpapi.io"

data = {
    "action": "getBalances",
    "privateKey": "base58_private_key",
    # "publicKey": "optional_other_wallet_address",
}

JavaScript

import axios from "axios";

const url = "https://api.pumpapi.io";

  action: "getBalances",
  privateKey: "base58_private_key",
  // publicKey: "optional_other_wallet_address",

axios
  .post(url, data)
  .then((res) => console.log(res.data))
  .catch((err) => console.error(err));

Rust

use reqwest::Client;
use serde_json::json;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = Client::new();

    let res = client
        .post("https://api.pumpapi.io")
        .json(&json!({
            "action": "getBalances",
            "privateKey": "base58_private_key",
            // "publicKey": "optional_other_wallet_address"
        }))
        .send()
        .await?
        .text()
        .await?;

    println!("{}", res);
    Ok(())
}

Go

package main

import (
	"bytes"
	"encoding/json"
	"fmt"
	"net/http"
)

func main() {
	url := "https://api.pumpapi.io"

	data := map[string]any{
		"action":     "getBalances",
		"privateKey": "base58_private_key",
		// "publicKey": "optional_other_wallet_address",
	}

	jsonData, _ := json.Marshal(data)

	resp, err := http.Post(url, "application/json", bytes.NewBuffer(jsonData))
	if err != nil {
		panic(err)
	}
	defer resp.Body.Close()

	var result any
	_ = json.NewDecoder(resp.Body).Decode(&result)
	fmt.Printf("%v\n", result)
}

Example Response

solBalance is a plain number in SOL. Each entry under tokenBalances is keyed by the token mint address, and balance. Tokens sitting in non-ATA accounts are skipped.

{
  "solBalance": 0.4231,
  "tokenBalances": {
    "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v": {
      "balance": 12.5,
      "tokenProgram": "spl-token"
    },
    "H74CYmXgMkYHYuSRsZt6RJb4NYp2u72Vw8BS5huApump": {
      "balance": 1000,
      "tokenProgram": "spl-token-2022"
      // "frozen": true  // appears only if you hit a scam token that froze your account (you can still burn such tokens)
    }
  }
}
