Read Market Data

Market state is readable through three channels: the REST API (best for dashboards and monitoring), the TypeScript SDK (best for integrations that compute derived values on-chain), and direct Solana RPC reads (for the lowest-level access). Most curators use the API for monitoring and the SDK for any integration that needs to react to market state.

Channels at a glance

Channel	Best for	Endpoint / package
REST API	Dashboards, alerts, integrations that need historical data	`https://api.kamino.finance`
TypeScript SDK	Apps computing live APYs, building transactions, reacting to state	`@kamino-finance/klend-sdk`
Direct RPC	Lowest-latency access, minimal dependencies	Solana RPC + the program’s account decoders

List all markets

// SDK loads individual markets by address; the API is the place to enumerate
const response = await fetch('https://api.kamino.finance/v2/kamino-market');
const markets = await response.json();

curl https://api.kamino.finance/v2/kamino-market

Returns the full set of klend markets the API knows about, with addresses and basic metadata.

Market-wide TVL and totals

import { createSolanaRpc, address } from '@solana/kit';
import { KaminoMarket, getMedianSlotDurationInMsFromLastEpochs } from '@kamino-finance/klend-sdk';

const rpc = createSolanaRpc('https://api.mainnet-beta.solana.com');
const slotDuration = await getMedianSlotDurationInMsFromLastEpochs();
const market = await KaminoMarket.load(rpc, address('<MARKET_ADDRESS>'), slotDuration);

console.log({
  depositTVL: market!.getTotalDepositTVL().toString(),
  borrowTVL:  market!.getTotalBorrowTVL().toString(),
});

curl https://api.kamino.finance/kamino-market/<MARKET_ADDRESS>/reserves/metrics

Per-reserve metrics

import { createSolanaRpc, address } from '@solana/kit';
import { KaminoMarket, getMedianSlotDurationInMsFromLastEpochs } from '@kamino-finance/klend-sdk';

const rpc = createSolanaRpc('https://api.mainnet-beta.solana.com');
const slotDuration = await getMedianSlotDurationInMsFromLastEpochs();
const market = await KaminoMarket.load(rpc, address('<MARKET_ADDRESS>'), slotDuration);
const slot = await rpc.getSlot().send();

for (const reserve of market!.getReserves()) {
  console.log(`Reserve ${reserve.symbol}:`);
  console.log(`  Deposit TVL:   ${reserve.getDepositTvl().toFixed(2)}`);
  console.log(`  Borrow TVL:    ${reserve.getBorrowTvl().toFixed(2)}`);
  console.log(`  Borrow APY:    ${reserve.totalBorrowAPY(slot)}%`);
  console.log(`  Supply APY:    ${reserve.totalSupplyAPY(slot)}%`);
  console.log(`  Utilization:   ${reserve.calculateUtilizationRatio()}%`);
}

const response = await fetch(
  'https://api.kamino.finance/kamino-market/<MARKET_ADDRESS>/reserves/metrics'
);
const { reserves } = await response.json();

reserves.forEach((reserve: any) => {
  console.log({
    address:    reserve.reserve,
    symbol:     reserve.symbol,
    depositTvl: reserve.metrics.depositTvl,
    borrowTvl:  reserve.metrics.borrowTvl,
    supplyAPY:  reserve.metrics.supplyInterestAPY,
    borrowAPY:  reserve.metrics.borrowInterestAPY,
  });
});

curl https://api.kamino.finance/kamino-market/<MARKET_ADDRESS>/reserves/metrics

Historical reserve metrics

Historical time-series data is API-only. The SDK reads live state; the API serves historical series.

const marketPubkey = '<MARKET_ADDRESS>';
const reservePubkey = '<RESERVE_ADDRESS>';

const url = `https://api.kamino.finance/kamino-market/${marketPubkey}/reserves/${reservePubkey}/metrics/history`;

const response = await fetch(url);
const { history } = await response.json();

for (const item of history) {
  console.log({
    timestamp:        item.timestamp,
    symbol:           item.metrics.symbol,
    supplyInterestAPY: item.metrics.supplyInterestAPY,
    borrowInterestAPY: item.metrics.borrowInterestAPY,
    depositTvl:       item.metrics.depositTvl,
    borrowTvl:        item.metrics.borrowTvl,
  });
}

curl "https://api.kamino.finance/kamino-market/<MARKET_ADDRESS>/reserves/<RESERVE_ADDRESS>/metrics/history"

Rewards data

The Kamino API exposes reward data such as active campaigns and per-user claimable amounts for klend reserves.

All active reward programs

const response = await fetch('https://api.kamino.finance/klend/rewards');
const rewards = await response.json();
console.log('Active KLend rewards:', rewards);

curl https://api.kamino.finance/klend/rewards

A user’s claimable rewards across all reserves

const userPubkey = '<USER_WALLET_ADDRESS>';
const response = await fetch(
  `https://api.kamino.finance/klend/users/${userPubkey}/rewards`
);
const rewards = await response.json();
console.log('User rewards:', rewards);

curl https://api.kamino.finance/klend/users/<USER_WALLET_ADDRESS>/rewards

Live farm state from the SDK

For real-time emission rates and on-chain farm balances, read the KFarms FarmState directly:

import { createSolanaRpc, address } from '@solana/kit';
import { KaminoMarket, getMedianSlotDurationInMsFromLastEpochs } from '@kamino-finance/klend-sdk';
import { FarmState } from '@kamino-finance/farms-sdk';

const rpc = createSolanaRpc('https://api.mainnet-beta.solana.com');
const slotDuration = await getMedianSlotDurationInMsFromLastEpochs();
const market = await KaminoMarket.load(rpc, address('<MARKET_ADDRESS>'), slotDuration);

for (const reserve of market!.getReserves()) {
  const collFarm = reserve.getCollateralFarmAddress();
  const debtFarm = reserve.getDebtFarmAddress();

  if (collFarm) {
    const farmState = await FarmState.fetch(rpc, collFarm);
    console.log(`${reserve.symbol} collateral farm:`, farmState);
  }
  if (debtFarm) {
    const farmState = await FarmState.fetch(rpc, debtFarm);
    console.log(`${reserve.symbol} debt farm:`, farmState);
  }
}

What the SDK exposes per reserve

reserve instances loaded via market.getReserves() provide the following getters:

Method	Returns
`reserve.symbol`	Token symbol
`reserve.address`	Reserve account pubkey
`reserve.getDepositTvl()`	Total USD value deposited
`reserve.getBorrowTvl()`	Total USD value borrowed
`reserve.totalBorrowAPY(slot)`	Combined borrow APY (curve + host fixed)
`reserve.totalSupplyAPY(slot)`	Supply-side APY paid to depositors
`reserve.calculateUtilizationRatio()`	Borrowed / deposited, as a fraction
`reserve.getCollateralFarmAddress()`	Farm address for the collateral side, or `null`
`reserve.getDebtFarmAddress()`	Farm address for the debt side, or `null`
`reserve.config`	The on-chain `ReserveConfig` (every editable parameter)

Direct RPC reads

For the lowest-level access (minimal dependencies, fastest reads, no SDK abstraction), fetch the on-chain accounts directly via Solana RPC and decode them with the program’s IDL or struct definitions. The relevant accounts:

Account	What it holds
`LendingMarket`	Market-level config + flags
`Reserve`	Per-reserve config + live state (liquidity, collateral, withdraw queue)
`Obligation`	Per-user position (deposits + borrows)
`FarmState`	KFarms reward state for a collateral or debt farm

See Programmatic integration for routing to the SDK and API documentation that covers each surface in depth.
