  const url = `${BASE_URL}/simple/networks/${NETWORK}/token_price/${tokenAddress}`;

  const response = await fetch(url, {
    headers: {
      [HEADER_KEY]: apiKey,
      'Accept': 'application/json',
    },
  });

  if (!response.ok) {
    throw new Error(`API error: ${response.status}`);
  }

  const data = await response.json();
  return data.data?.attributes?.token_prices?.[tokenAddress] ?? null;
}

// Usage
const USDC = 'EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v';

---

Best Practices

Security

• Never commit API keys to git
• Use environment variables
• Rotate keys periodically
• Use separate keys for dev/prod

Performance

• Batch token requests when possible
• Cache frequently accessed data
• Use appropriate timeframes for OHLCV
• Implement request queuing for rate limits

Data Quality

• Verify market cap data (may be null if unverified)
• Check pool liquidity before trusting prices
• Use multiple timeframes for price analysis
• Monitor last trade timestamp for activity

Quick Start

Installation

# TypeScript/JavaScript
npm install @pythnetwork/hermes-client @pythnetwork/pyth-solana-receiver

# Rust (add to Cargo.toml)
# pyth-solana-receiver-sdk = "0.3.0"

Fetch Price (Off-Chain)

import { HermesClient } from "@pythnetwork/hermes-client";

const client = new HermesClient("https://hermes.pyth.network");

const priceIds = [
  "0xe62df6c8b4a85fe1a67db44dc12de5db330f7ac66b72dc658afedf0f4a415b43", // BTC/USD
];

const priceUpdates = await client.getLatestPriceUpdates(priceIds);

for (const update of priceUpdates.parsed) {
  const price = update.price;
  const displayPrice = Number(price.price) * Math.pow(10, price.expo);
  console.log(`Price: $${displayPrice.toFixed(2)}`);
  console.log(`Confidence: ±${Number(price.conf) * Math.pow(10, price.expo)}`);
}

Use Price On-Chain (Rust/Anchor)

use anchor_lang::prelude::*;
use pyth_solana_receiver_sdk::price_update::PriceUpdateV2;

#[derive(Accounts)]
pub struct UsePrice<'info> {
    pub price_update: Account<'info, PriceUpdateV2>,
}

pub fn use_price(ctx: Context<UsePrice>) -> Result<()> {
    let price_update = &ctx.accounts.price_update;
    let clock = Clock::get()?;

    // Get price no older than 60 seconds
    let price = price_update.get_price_no_older_than(
        &clock,
        60, // max age in seconds
    )?;

    msg!("Price: {} × 10^{}", price.price, price.exponent);
    msg!("Confidence: ±{}", price.conf);

    Ok(())
}

Core Concepts

Price Structure

Each Pyth price contains:

Field	Type	Description
price	i64	Price value in fixed-point format
conf	u64	Confidence interval (standard deviation)
expo	i32	Exponent for scaling (e.g., -8 means divide by 10^8)
publish_time	i64	Unix timestamp of price

Converting to display price:

const displayPrice = price * Math.pow(10, expo);
// Example: price=19405100, expo=-2 → $194,051.00

Confidence Intervals

Confidence intervals represent the uncertainty in the reported price:

// Price is $50,000 ± $50 means:
// - 68% chance true price is between $49,950 - $50,050
// - Use confidence for risk management

const price = 50000;
const confidence = 50;

// Safe lower bound (conservative)
const safeLowerBound = price - confidence;

// Safe upper bound (conservative)
const safeUpperBound = price + confidence;

Best Practice: Reject prices with confidence > 2% of price:

const maxConfidenceRatio = 0.02; // 2%
const confidenceRatio = confidence / Math.abs(price);

if (confidenceRatio > maxConfidenceRatio) {
  throw new Error("Price confidence too wide");
}

EMA Prices

Exponential Moving Average prices smooth out short-term volatility:

• ~1 hour averaging window (5921 Solana slots)
• Weighted by inverse confidence (tight confidence = more weight)
• Good for: liquidations, collateral valuation
• Available as ema_price and ema_conf

// Use EMA for less volatile applications
const emaPrice = priceUpdate.emaPrice;
const emaConf = priceUpdate.emaConf;

---

Off-Chain Integration

Hermes Client

Hermes is the recommended way to fetch Pyth prices off-chain.

Public Endpoint: https://hermes.pyth.network

For production, get a dedicated endpoint from a Pyth data provider.

Fetching Latest Prices

import { HermesClient } from "@pythnetwork/hermes-client";

const client = new HermesClient("https://hermes.pyth.network");

]);

// Multiple prices in one request
const prices = await client.getLatestPriceUpdates([

Streaming Real-Time Updates

import { HermesClient } from "@pythnetwork/hermes-client";

const client = new HermesClient("https://hermes.pyth.network");

const priceIds = [
  "0xe62df6c8b4a85fe1a67db44dc12de5db330f7ac66b72dc658afedf0f4a415b43"

// Subscribe to real-time updates via SSE
const eventSource = await client.getPriceUpdatesStream(priceIds, {
  parsed: true,
});

  const data = JSON.parse(event.data);
  console.log("Price update:", data);
};

eventSource.onerror = (error) => {
  console.error("Stream error:", error);
  eventSource.close();

Posting Prices to Solana

import { PythSolanaReceiver } from "@pythnetwork/pyth-solana-receiver";
import { HermesClient } from "@pythnetwork/hermes-client";
import { Connection, Keypair } from "@solana/web3.js";

const connection = new Connection("https://api.mainnet-beta.solana.com");
const wallet = Keypair.fromSecretKey(/* your key */);

const hermesClient = new HermesClient("https://hermes.pyth.network");
const pythReceiver = new PythSolanaReceiver({ connection, wallet });

// Fetch price update data
const priceUpdateData = await hermesClient.getLatestPriceUpdates([
  "0xe62df6c8b4a85fe1a67db44dc12de5db330f7ac66b72dc658afedf0f4a415b43"
]);

// Build transaction to post price
const transactionBuilder = pythReceiver.newTransactionBuilder();
await transactionBuilder.addPostPriceUpdates(priceUpdateData.binary.data);

// Add your program instruction that uses the price
// transactionBuilder.addInstruction(yourInstruction);

// Send transaction
const transactions = await transactionBuilder.buildVersionedTransactions({
  computeUnitPriceMicroLamports: 50000,
});

for (const tx of transactions) {
  const sig = await connection.sendTransaction(tx);
  console.log("Transaction:", sig);

On-Chain Integration (Rust)

Setup

Add to Cargo.toml:

[dependencies]
pyth-solana-receiver-sdk = "0.3.0"
anchor-lang = "0.30.1"

Reading Price in Anchor Program

use anchor_lang::prelude::*;
use pyth_solana_receiver_sdk::price_update::{PriceUpdateV2, get_feed_id_from_hex};

declare_id!("YourProgramId...");

// BTC/USD price feed ID
const BTC_USD_FEED_ID: &str = "0xe62df6c8b4a85fe1a67db44dc12de5db330f7ac66b72dc658afedf0f4a415b43";

#[program]
pub mod my_program {
    use super::*;

    pub fn check_price(ctx: Context<CheckPrice>) -> Result<()> {
        let price_update = &ctx.accounts.price_update;
        let clock = Clock::get()?;

        // Verify this is the correct feed
        let feed_id = get_feed_id_from_hex(BTC_USD_FEED_ID)?;

        // Get price no older than 60 seconds
        let price = price_update.get_price_no_older_than_with_custom_verification(
            &clock,
            60,
            &feed_id,
            ctx.accounts.price_update.to_account_info().owner,
        )?;

        msg!("BTC/USD Price: {} × 10^{}", price.price, price.exponent);
        msg!("Confidence: ±{}", price.conf);

        Ok(())
    }
}

#[derive(Accounts)]
pub struct CheckPrice<'info> {

Using Price for Calculations

pub fn swap_with_oracle(
    ctx: Context<SwapWithOracle>,
    amount_in: u64,
) -> Result<()> {
    let price_update = &ctx.accounts.price_update;
    let clock = Clock::get()?;

    // Get price with staleness check
    let price = price_update.get_price_no_older_than(&clock, 30)?;

    // Validate confidence (max 1% of price)
    let conf_ratio = (price.conf as u128 * 10000) / (price.price.unsigned_abs() as u128);
    require!(conf_ratio <= 100, ErrorCode::ConfidenceTooWide);

    // Convert price to usable format
    // price.price is in fixed-point with price.exponent
    let price_scaled = if price.exponent >= 0 {
        (price.price as u128) * 10_u128.pow(price.exponent as u32)
    } else {
        (price.price as u128) / 10_u128.pow((-price.exponent) as u32)
    };

    // Calculate output amount using oracle price
    let amount_out = (amount_in as u128)
        .checked_mul(price_scaled)
        .ok_or(ErrorCode::MathOverflow)?
        / 1_000_000; // Adjust for decimals

    msg!("Swap {} -> {} using price {}", amount_in, amount_out, price_scaled);

    Ok(())

#[error_code]
pub enum ErrorCode {

Multiple Price Feeds

#[derive(Accounts)]
pub struct Liquidation<'info> {
    #[account(
        constraint = collateral_price.to_account_info().owner == &pyth_solana_receiver_sdk::ID
    )]
    pub collateral_price: Account<'info, PriceUpdateV2>,

    #[account(
        constraint = debt_price.to_account_info().owner == &pyth_solana_receiver_sdk::ID
    )]
    pub debt_price: Account<'info, PriceUpdateV2>,
}

pub fn check_liquidation(ctx: Context<Liquidation>) -> Result<bool> {
    let clock = Clock::get()?;

    let collateral = ctx.accounts.collateral_price
        .get_price_no_older_than(&clock, 60)?;
    let debt = ctx.accounts.debt_price
        .get_price_no_older_than(&clock, 60)?;

    // Normalize to same exponent for comparison
    let collateral_value = normalize_price(collateral.price, collateral.exponent);
    let debt_value = normalize_price(debt.price, debt.exponent);

    // Check if undercollateralized
    let is_liquidatable = collateral_value < debt_value * 150 / 100; // 150% ratio

    Ok(is_liquidatable)
}

fn normalize_price(price: i64, expo: i32) -> i128 {
    let target_expo = -8; // Normalize to 8 decimals
    let adjustment = expo - target_expo;

    if adjustment >= 0 {
        (price as i128) * 10_i128.pow(adjustment as u32)
    } else {
        (price as i128) / 10_i128.pow((-adjustment) as u32)
    }
}

Best Practices

1. Always Check Staleness

// Don't use old prices - set appropriate max age
let max_age_seconds = 60;
let price = price_update.get_price_no_older_than(&clock, max_age_seconds)?;

2. Validate Confidence Intervals

// Reject prices with wide confidence (high uncertainty)
const MAX_CONF_BPS: u64 = 200; // 2%

let conf_bps = (price.conf as u128 * 10000) / (price.price.unsigned_abs() as u128);
require!(conf_bps <= MAX_CONF_BPS as u128, ErrorCode::ConfidenceTooWide);

3. Verify Account Ownership

// Always verify the price account is owned by Pyth
#[account(
    constraint = price_update.to_account_info().owner == &pyth_solana_receiver_sdk::ID
)]
pub price_update: Account<'info, PriceUpdateV2>,

4. Use EMA for Sensitive Operations

// For liquidations, use EMA to avoid manipulation
let ema_price = price_update.get_ema_price_no_older_than(&clock, 60)?;

5. Handle Price Unavailability

try {
  const price = await client.getLatestPriceUpdates([feedId]);
  // Use price
} catch (error) {
  // Fallback behavior or reject transaction
  console.error("Price unavailable:", error);
}

6. Consider Frontrunning

• Adversaries may see price updates before your transaction
• Don't design logic that races against price updates
• Use appropriate slippage tolerances

Price Feed Types

Fixed Price Feed Accounts

• Maintained continuously by Pyth
• Fixed address per feed
• Always has most recent price
• Shared by all users (potential congestion)

Ephemeral Price Update Accounts

• Created per transaction
• Can specify shard ID for parallelization
• Rent can be recovered after use
• Better for high-throughput applications

// Use shard ID to avoid congestion
const transactionBuilder = pythReceiver.newTransactionBuilder({
  shardId: Math.floor(Math.random() * 65536), // Random shard
});

Pyth on EVM Chains

This skill covers Pyth integration for Solana applications using Anchor CPI. For EVM chain integration (Ethereum, Arbitrum, Base, Optimism, Polygon, and 50+ other chains), see the pyth-evm skill.

Key differences between Pyth Solana and Pyth EVM:

Aspect	Pyth Solana (this skill)	Pyth EVM (pyth-evm skill)
Contract interface	Anchor CPI to Pyth program	Solidity IPyth interface
Price update	Pull from Pyth accumulator account	Submit bytes[] via updatePriceFeeds
Contract address	Single Pyth program on Solana	Varies per EVM chain
Gas/compute	Compute units	~120-150K gas per feed update
SDK	@pythnetwork/pyth-solana-receiver	@pythnetwork/hermes-client v3.1.0

Price feed IDs (bytes32) are the same across all chains — a BTC/USD feed ID works on both Solana and Ethereum.
