Access to real-time cryptocurrency prices is essential for anyone building apps, research tools, or bots in the crypto space. With countless digital assets and rapid price movements, quality data feeds are in high demand. But is there a free or cheap API that provides real-time crypto prices? In this guide, we break down your options, compare major providers, and explain the trade-offs when looking for budget-friendly API solutions.

Understanding Crypto Price APIs

Crypto price APIs are services that deliver up-to-the-second market data for cryptocurrencies. These APIs aggregate information from exchanges and other sources, normalize data, and provide endpoints that developers or analysts can programmatically access. They fuel:

  • Portfolio trackers
  • Trading bots
  • Research dashboards
  • Accounting and compliance tools
  • AI agents that analyze crypto markets in real time

The quality of a crypto price API comes down to a few core factors: data accuracy, coverage of exchanges and coins, API uptime, update frequency, latency, and—crucially—price.

Free Crypto Price API Options

Several providers offer a limited API tier at no cost, suitable for prototypes, personal projects, or educational use. Here are some notable free API choices:

  • CoinGecko API: Fully free, broad coin and exchange coverage, generous rate limits—good for non-commercial uses. Drawbacks include potential data delays and lack of advanced features.
  • CoinCap API: Also free and covers major assets with basic price and market cap endpoints. Less comprehensive than some paid solutions.
  • Binance API: Fully free for spot prices, order books, and trading pairs on Binance. Limited to Binance's own data, but excellent depth and reliability.
  • CryptoCompare API: Offers a free tier with basic endpoints and limited requests per day. Good for initial prototypes.

These options provide excellent value at zero cost but may be restrictive for commercial apps or high-frequency needs. Free APIs often offer lower rate limits, partial data (vs. real aggregated global prices), and less responsive customer support.

When to Consider Affordable Paid APIs

As requirements grow—think higher update frequency, greater reliability, or advanced analytics—free APIs may fall short. Entry-level paid tiers are designed for startups, indie developers, and small teams that find free plans too limiting, yet don’t require enterprise-level solutions. Typical advantages include:

  • Faster refresh rates (often near real-time, depending on provider)
  • Higher monthly rate limits
  • Expanded endpoint selection (historical prices, technical indicators, derivatives data, etc.)
  • Priority technical support
  • Higher SLA (service-level agreement) guarantees on uptime

Popular affordable options include:

  • CoinMarketCap API: Paid plans start around $29/month, covering hundreds of coins, robust data points, and enhanced refresh speed.
  • Nomics API: Offers reliable market data, with entry plans catering to startups and research projects.
  • Token Metrics API: Combines real-time prices and analytics in a single API designed for smart crypto applications and AI tools, with scalable tiers.
  • CryptoCompare API (paid tiers): Adds more powerful endpoints and better performance over free account.

It's worth evaluating how much "real-time" performance and depth your use case truly requires, as this will inform whether a free, cheap, or more premium tier is necessary.

What to Look for in a Crypto Price API

API selection comes down to both core features and contextual requirements. Consider these checkpoints:

  • Coverage: How many exchanges and coins does the API support?
  • Data Freshness: Is pricing real-time (tick-by-tick), or does it update every few seconds/minutes?
  • Reliability: What uptime and latency can you expect?
  • Rate Limits: Are the free or cheap tiers sufficient for your app’s needs?
  • Support: Is there responsive documentation and technical support?
  • Extra Analytics: Does the API offer expert signals, on-chain data, or AI-enhanced analysis?
  • License and Terms: Are there any non-commercial use restrictions on their free plan, or limits around redistribution?

For rapid prototyping, free APIs are great. For mission-critical apps, especially those requiring AI-powered analytics, a paid solution with more advanced features and support might be essential.

How Developers Use Crypto Price APIs in Practice

Real-time data APIs are integrated in a variety of ways. Developers often:

  • Refresh app dashboards with live crypto prices on demand
  • Feed AI models for portfolio simulations, price anomaly detection, or sentiment analysis
  • Trigger alerts when certain assets cross price thresholds
  • Backtest trading strategies using historical endpoints
  • Aggregate data from multiple sources for added redundancy and confidence

It's critical to match your API choice with your technical stack and performance needs. Fortunately, competitive options mean even budget-constrained projects can access real-time data. Many tools, such as Token Metrics, layer advanced analytics and AI research over raw price feeds, providing more actionable information for users and researchers.

Frequently Asked Questions

Which free crypto price API is most reliable?

Among free APIs, CoinGecko and Binance are highly regarded for consistent uptime and comprehensive coverage. Still, their free tiers may have lower priority and reduced guarantees compared to paid options.

What does 'real-time' mean in crypto APIs?

Real-time typically refers to data updates as soon as they become available, with latencies of under a second to a few seconds. Not all "free" APIs deliver true tick-by-tick price feeds due to technical and cost constraints.

Can free APIs be used for commercial projects?

Some free APIs restrict usage to non-commercial applications. Always check provider terms of service before integrating a free API with any monetized product.

How are AI and analytics integrated with price APIs?

Platforms like Token Metrics layer on-chain analytics and AI-powered signals on top of real-time price feeds. This helps advanced users derive deeper insights beyond basic tick data.

What are the main limitations of free crypto APIs?

Limitations typically include lower request limits, delayed data updates, restricted support, and less comprehensive data sets. For higher volume or critical use, a paid tier may be necessary.

⚙️ How to Connect Token Metrics API to Google Sheets

Here’s how to get live AI-powered crypto data into Sheets using Google Apps Script.

🔑 Step 1: Generate Your API Key

  1. Visit: https://app.tokenmetrics.com/en/api
  2. Click “Generate API Key”
  3. Copy it — you’ll use this in the script

📄 Step 2: Create a New Google Sheet

  1. Go to Google Sheets
  2. Create a new spreadsheet
  3. Click Extensions > Apps Script

💻 Step 3: Paste This Apps Script

const TOKEN_METRICS_API_KEY = 'YOUR_API_KEY_HERE';

async function getTraderGrade(symbol) {

  const url = `https://api.tokenmetrics.com/v2/trader-grades?symbol=${symbol.toUpperCase()}`;

  const options = {

    method: 'GET',

    contentType: 'application/json',

    headers: {

      'accept': 'application/json',

      'x-api-key': TOKEN_METRICS_API_KEY,

    },

    muteHttpExceptions: true

  };

  

  const response = UrlFetchApp.fetch(url, options);

  const data = JSON.parse(response.getContentText() || "{}")

  

  if (data.success && data.data.length) {

    const coin = data.data[0];

    return [

      coin.TOKEN_NAME,

      coin.TOKEN_SYMBOL,

      coin.TA_GRADE,

      coin.DATE

    ];

  } else {

    return ['No data', '-', '-', '-'];

  }

}

async function getSheetData() {

  const sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();

  const symbols = sheet.getRange('A2:A').getValues().flat().filter(Boolean);

  const results = [];

  results.push(['Name', 'Symbol', 'Trader Grade', 'Date']);

  for (const symbol of symbols) {

    if (symbol) {

      const row = await getTraderGrade(symbol);

      results.push(row);

    }

  }

  sheet.getRange(2, 2, results.length, results[0].length).setValues(results);

}

🧪 Step 4: Run the Script

  1. Replace 'YOUR_API_KEY_HERE' with your real API key.
  2. Save the project as TokenMetricsCryptoAPI.
  3. In your sheet, enter a list of symbols (e.g., BTC, ETH, SOL) in Column A.
  4. Go to the script editor and run getSheetData() from the dropdown menu.

Note: The first time, Google will ask for permission to access the script.

✅ Step 5: View Your Live Data

After the script runs, you’ll see:

  • Coin name and symbol
  • Trader Grade (0–100)
  • Timestamp

You can now:

  • Sort by Trader Grade
  • Add charts and pivot tables
  • Schedule automatic updates with triggers (e.g., every hour)

🧠 Why Token Metrics API Is Ideal for Google Sheets Users

Unlike basic price APIs, Token Metrics offers AI-driven metrics that help you:

🚀Put Your $TMAI to Work: Daily Rewards, No Locks, Up To 200% APR.

Token Metrics Team
5 min
MIN

Liquidity farming just got a major upgrade. Token Metrics AI ($TMAI) has launched its first liquidity incentive campaign on Merk — and it’s designed for yield hunters looking to earn fast, with no lockups, no gimmicks, and real rewards from Day 1.

📅 Campaign Details

  • Duration: June 5 – June 19, 2025
  • Rewards Begin: 17:00 UTC / 1:00 PM ET
  • Total TMAI Committed: 38 million+ $TMAI
  • No Lockups: Enter or exit at any time
  • APR Potential: Up to 200%

For two weeks, liquidity providers can earn high daily rewards across three different pools. All rewards are paid in $TMAI and distributed continuously — block by block — through the Merkl platform.

💧 Where to Earn – The Pools (as of June 5, 17:00 UTC)

Pool                                                    Starting APR %               Total Rewards (14 days)                Current TVL

Aerodrome WETH–TMAI        150%                                16.79M TMAI (~$11,000)                   $86,400

Uniswap v3 USDC–TMAI        200%                                14.92M TMAI (~$9,800)                    $19,900

Balancer 95/5 WETH–TMAI    200%                                5.60M TMAI (~$3,700)                       $9,500

These pools are live and actively paying rewards. APR rates aren’t displayed on Merkl until the first 24 hours of data are available — but early providers will already be earning.

🧠 Why This Campaign Stands Out

1. Turbo Rewards for a Short Time

This isn’t a slow-drip farm. The TMAI Merkl campaign is designed to reward action-takers. For the first few days, yields are especially high — thanks to low TVL and full daily reward distribution.

2. No Lockups or Waiting Periods

You can provide liquidity and withdraw it anytime — even the same day. There are no lockups, no vesting, and no delayed payout mechanics. All rewards accrue automatically and are claimable through Merkl.

3. Choose Your Risk Profile

You get to pick your exposure.

  • Want ETH upside? Stake in Aerodrome or Balancer.
  • Prefer stablecoin stability? Go with the Uniswap v3 USDC–TMAI pool.

4. Influence the Future of TMAI Yield Farming

This campaign isn’t just about yield — it’s a test. If enough users participate and volume grows, the Token Metrics Treasury will consider extending liquidity rewards into Q3 and beyond. That means more TMAI emissions, longer timelines, and consistent passive income opportunities for LPs.

5. Built for Transparency and Speed

Rewards are distributed via Merkl by Angle Labs, a transparent, gas-efficient platform for programmable liquidity mining. You can see the exact rewards, TVL, wallet counts, and pool analytics at any time.

🔧 How to Get Started

Getting started is simple. You only need a crypto wallet, some $TMAI, and a matching asset (either WETH or USDC, depending on the pool).

Step-by-step:

  1. Pick a pool:
    Choose from Aerodrome, Uniswap v3, or Balancer depending on your risk appetite and asset preference.

  2. Provide liquidity:
    Head to the Merkl link for your pool, deposit both assets, and your position is live immediately.

  3. Track your earnings:
    Watch TMAI accumulate daily in your Merkl dashboard. You can claim rewards at any time.

  4. Withdraw when you want:
    Since there are no lockups, you can remove your liquidity whenever you choose — rewards stop the moment liquidity is pulled.

🎯 Final Thoughts

This is a rare opportunity to earn serious rewards in a short amount of time. Whether you’re new to liquidity mining or a DeFi veteran, the TMAI Merkl campaign is built for speed, flexibility, and transparency.

You’re still early. The best yields happen in the first days, before TVL rises and APR stabilizes. Dive in now and maximize your returns while the turbo phase is still on.

Token Metrics API Joins RapidAPI: The Fastest Way to Add AI-Grade Crypto Data to Your App

Token Metrics Team
5 min

The hunt for a dependable Crypto API normally ends in a graveyard of half-maintained GitHub repos, flaky RPC endpoints, and expensive enterprise feeds that hide the true cost behind a sales call. Developers waste days wiring those sources together, only to learn that one fails during a market spike or that data schemas never quite align. The result? Bots mis-fire, dashboards drift out of sync, and growth stalls while engineers chase yet another “price feed.”

That headache stops today. Token Metrics API, the same engine that powers more than 70 000 users on the Token Metrics analytics platform, is now live on RapidAPI—the largest marketplace of public APIs with more than four million developers. One search, one click, and you get an AI-grade Crypto API with institutional reliability and a 99.99 % uptime SLA.

Why RapidAPI + Token Metrics API Matters

  • Native developer workflow – No separate billing portal, OAuth flow, or SDK hunt. Click “Subscribe,” pick the Free plan, and RapidAPI instantly generates a key.

  • Single playground – Run test calls in-browser and copy snippets in cURL, Python, Node, Go, or Rust without leaving the listing.

  • Auto-scale billing – When usage grows, RapidAPI handles metering and invoices. You focus on product, not procurement.

What Makes the Token Metrics Crypto API Different?

  1. Twenty-one production endpoints

    Live & historical prices, hourly and daily OHLCV, proprietary Trader & Investor Grades, on-chain and social sentiment, AI-curated sector indices, plus deep-dive AI reports that summarise fundamentals, code health, and tokenomics.

  2. AI signals that win

    Over the last 24 months, more than 70 % of our bull/bear signals outperformed simple buy-and-hold. The API delivers that same alpha in flat JSON.

  3. Institutional reliability

    99.99 % uptime, public status page, and automatic caching for hot endpoints keep latency low even on volatile days.

Three-Step Quick Start

  1. Search “Token Metrics API” on RapidAPI and click Subscribe.
  2. Select the Free plan (5 000 calls / month, 20 request / min) and copy your key.
  3. Test:
