Hello @C_K could u share with us what are the exactly endpoints and parameters are you calling on the Klever API?
---
### Author:  [@C\_K](https://forum.klever.org/u/C_K)
#### Post date: [July 20, 2025, 3:43pm UTC](https://forum.klever.org/t/token-data-and-kleverscan-api-issue/3933/3 "2025-07-20T15:43:02Z")
here are the exact Klever API endpoints and parameters being called:
## 1. KleverScan API (Primary)
**Base URL** : `https://api.kleverscan.org`
### Account Data Endpoints (tried in order):
```typescript
const ACCOUNT_API_ENDPOINTS = [
"https://api.kleverscan.org/v1.0/address/{address}",
"https://api.kleverscan.org/address/{address}",
"https://api.kleverscan.org/v1/accounts/{address}",
"https://api.kleverscan.org/accounts/{address}",
]
```
**Parameters** :
- `{address}` - Klever wallet address (e.g., `klv1abc...`)
**Headers** :
```typescript
{
"Accept": "application/json",
"User-Agent": "GRT-DAO-App/1.0",
"Cache-Control": "no-cache"
}
```
## 2. Official Klever API (Fallback)
**Base URL** : `https://api.mainnet.klever.finance/public/v1`
### Endpoints Used:
#### Get Account:
```plaintext
GET /account/{address}
```
#### Get Account Assets:
```plaintext
GET /account/{address}/assets
GET /account/{address}/balances // Alternative
```
#### Get Asset Info:
```plaintext
GET /asset/{assetId}
```
#### Search Assets:
```plaintext
GET /assets?search={query}
```
**Parameters** :
- `{address}` - Wallet address
- `{assetId}` - Asset identifier (e.g., “GRT-1B15”, “GRTVIP-1WOC”)
- `{query}` - Search term for assets
## 3. Asset IDs Being Searched
```typescript
export const ASSET_IDS = {
GRT: "GRT-1B15", // Genius Revenue Token
GRTVIP: "GRTVIP-1WOC" // Genius VIP Pass
}
const ASSET_ALTERNATIVES = {
GRT: ["GRT-1B15", "GRT", "Genius Revenue Token"],
GRTVIP: ["GRTVIP-1WOC", "GRTVIP", "Genius VIP Pass", "VIP"]
}
```
## 4. Proxy Endpoints (Browser)
When running in browser, requests go through proxy endpoints:
```plaintext
/api/klever-proxy/[...path] → https://api.kleverscan.org/[path]
/api/klever-official-proxy/[...path] → https://api.mainnet.klever.finance/public/v1/[path]
```
## 5. Example API Calls
### Get Account Balance:
```plaintext
GET https://api.kleverscan.org/v1.0/address/klv1abc123...
```
### Get Asset Info:
```plaintext
GET https://api.mainnet.klever.finance/public/v1/asset/GRT-1B15
```
### Search for Assets:
```plaintext
GET https://api.mainnet.klever.finance/public/v1/assets?search=GRT
```
## 6. Response Parsing
The code handles multiple response structures:
```typescript
// For account data
accountData.balances || accountData.assets || accountData.data?.balances
// For asset balance
balance.balance || balance.amount || balance.value || balance.quantity
// For asset ID
balance.assetId || balance.asset || balance.kda || balance.id
```

@C_K as u can see in details [here](https://forum.klever.org/t/important-notice-migration-from-klever-finance-to-klever-org-immediate-action-required/3745) please use the [klever.org](http://klever.org) instead of klever.finance endpoint

method being used to retrieve asset balances:
## **Current Asset Balance Retrieval Method:**
### **Primary Function: `getAccountInfo(address)`**
The app tries these methods **in order** until one succeeds:
```javascript
// ---------- 1) Provider RPC: klv_getAccount ----------
if (kleverWeb.provider?.request) {
try {
const accountInfo = await kleverWeb.provider.request({
method: "klv_getAccount",
params: [address],
})
if (accountInfo && (accountInfo.balance || accountInfo.assets)) {
return {
balance: accountInfo.balance ?? "0",
assets: accountInfo.assets ?? {},
}
}
} catch (err) {
console.log("klv_getAccount RPC failed:", err)
}
}
// ---------- 2) Provider RPC: klv_getBalance + klv_getAssets ----------
if (kleverWeb.provider?.request) {
try {
const rawBal = await kleverWeb.provider.request({
method: "klv_getBalance",
params: [address],
})
const rawAssets = await kleverWeb.provider.request({
method: "klv_getAssets",
params: [address],
})
const balance = typeof rawBal === "string" ?
Number.parseInt(rawBal, 16).toString() :
(rawBal?.toString?.() ?? "0")
return {
balance,
assets: rawAssets ?? {},
}
} catch (err) {
console.log("klv_getBalance / klv_getAssets RPC failed:", err)
}
}
// ---------- 3) Wallet communication bridge ----------
if (kleverWeb.communication?.getAccount) {
try {
const accountInfo = await kleverWeb.communication.getAccount(address)
return {
balance: accountInfo.balance ?? "0",
assets: accountInfo.assets ?? {},
}
} catch (err) {
console.log("communication.getAccount failed:", err)
}
}
// ---------- 4) Direct wallet properties ----------
if (kleverWeb.balance !== undefined || kleverWeb.assets) {
return {
balance: kleverWeb.balance?.toString?.() ?? "0",
assets: kleverWeb.assets ?? {},
}
}
// ---------- 5) External APIs ----------
const apiCandidates = [
`${KLEVER_CONSTANTS.KLEVER_API_URL}/account/${address}`,
`${KLEVER_CONSTANTS.KLEVERSCAN_URL}/api/account/${address}`,
`${KLEVER_CONSTANTS.KLEVER_NODE_URL}/account/${address}`,
]
```
### **Asset Processing Logic:**
Once account data is retrieved, assets are processed like this:
```javascript
// Add KLV balance (native token)
const balance = accountInfo.balance || "0"
tokenBalances.push({
symbol: "KLV",
name: getTokenName("KLV"),
balance: balance,
formattedBalance: formatTokenBalance(balance, "KLV"),
isNative: true,
})
// Add other token balances from assets
if (accountInfo.assets && typeof accountInfo.assets === "object") {
Object.entries(accountInfo.assets).forEach(([tokenSymbol, balance]) => {
if (tokenSymbol !== "KLV" && balance && balance !== "0") {
tokenBalances.push({
symbol: tokenSymbol,
name: getTokenName(tokenSymbol),
balance: balance,
formattedBalance: formatTokenBalance(balance, tokenSymbol),
isNative: false,
})
}
})
}
```

Hi @C_K I’ve seen some inconsistencies in the URLs you’re using, Ex.: We con’t recognize the [https://api.kleverscan.org](https://api.kleverscan.org) nor /api/klever-official-proxy/account/ either.
The officials Klever Blockchain root API end-points are:
- Testnet → [https://api.testnet.klever.org](https://api.testnet.klever.org)
- Mainnet → [https://api.mainnet.klever.org](https://api.mainnet.klever.org)
Please, check your calls by [Swagger UI](https://api.testnet.klever.org/swagger/index.html)
