What it does
Crypto Price Data Guide is an agent skill from nirholas/three.ws. How cryptocurrency prices work — the complete data pipeline from CEX order books and DEX pools through oracle networks to aggregators. Covers free API alternatives to CoinGecko, VWAP/TWAP calculations, and building price feeds without paid APIs. Use when explaining price sources, building market data features, or comparing data providers.
Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Data & Analytics, covering Crypto and DeFi analysis, Data pipelines and ETL and Stock and market analysis. It works with Binance, Arbitrum and Uniswap. The repository describes itself as: Open-source platform for 3D AI agents. Turn text or a photo into a rigged, animated GLB avatar, give it an LLM brain, memory and a wallet, and embed it anywhere with one web… The licence is MIT.
When your agent uses it
- Explaining price sources
- Building market data features
- Comparing data providers
Example prompts
- “/crypto-price-data-guide”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Direct RPC — Call pool contracts to read reserves/sqrtPrice
- The Graph — Query indexed swap events via GraphQL
- DexScreener API — Aggregated DEX data across 80+ chains
What it can do on your machine
Read from SKILL.md and the folder at commit 238ef60. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
api.binance.comapi.dexscreener.comhermes.pyth.networkcoins.llama.fiapi.coincap.ioapi.coinpaprika.commin-api.cryptocompare.com
Also links to:
defillama.combinance-docs.github.iodata.chain.linkdocs.dexscreener.comdocs.coincap.iopyth.network
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Crypto Price Data Guide loads about 2.7k tokens when it runs. Until then it costs about 91 tokens; SKILL.md has 737 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

└──────────────────────────────────────────────────────────┘Layer 1: Primary Price Sources
Centralized Exchange (CEX) APIs
CEXes are the dominant price source for high-cap tokens. Their order books determine the "true" price through supply/demand matching.
| Exchange | Public API | Rate Limit | WebSocket |
|---|---|---|---|
| Binance | api.binance.com/api/v3/ | 1200 req/min | ✅ Real-time |
| Coinbase | api.exchange.coinbase.com/ | 10 req/sec | ✅ Real-time |
| Kraken | api.kraken.com/0/public/ | 1 req/sec | ✅ Real-time |
| OKX | okx.com/api/v5/market/ | 20 req/2sec | ✅ Real-time |
| Bybit | api.bybit.com/v5/market/ | 120 req/sec | ✅ Real-time |
All of these are free, no API key required for public market data.
Example: Binance Spot Price
GET https://api.binance.com/api/v3/ticker/price?symbol=BTCUSDT
Response: { "symbol": "BTCUSDT", "price": "64523.45000000" }Example: Binance 24h Ticker
GET https://api.binance.com/api/v3/ticker/24hr?symbol=ETHUSDT
Response: {
"symbol": "ETHUSDT",
"priceChange": "45.20",
"priceChangePercent": "1.42",
"lastPrice": "3245.67",
"volume": "584231.45",
"highPrice": "3289.00",
"lowPrice": "3178.23"
}DEX On-Chain Data
For tokens that aren't listed on CEXes (the long tail), DEX pools are the only price source.
| Source | Chains | How Price Is Determined |
|---|---|---|
| Uniswap V2 | ETH, Arbitrum, etc. | Constant product: price = reserveB / reserveA |
| Uniswap V3 | ETH, Arbitrum, etc. | Square root price from pool slot0: sqrtPriceX96 |
| Curve | ETH, Arbitrum, etc. | StableSwap invariant (optimized for pegged assets) |
| Camelot | Arbitrum | V2 + V3 pools (Arbitrum-native) |
Reading DEX prices:
- Direct RPC — Call pool contracts to read reserves/sqrtPrice
- The Graph — Query indexed swap events via GraphQL
- DexScreener API — Aggregated DEX data across 80+ chains
DexScreener Example
GET https://api.dexscreener.com/latest/dex/tokens/0xD74f5255D557944cf7Dd0E45FF521520002D5748
Returns: SPA pair data across all DEXesHow CEX and DEX Prices Stay in Sync
Arbitrage bots. If ETH is $3,200 on Binance but $3,210 on Uniswap:
- Bot buys on Binance (cheaper)
- Bot sells on Uniswap (expensive)
- Price difference narrows until it's less than gas + bridge costs
This is why prices across venues are usually within 0.1–0.5% of each other.
Layer 2: Oracle Networks
Oracles aggregate CEX + DEX data and make it available on-chain for smart contracts.
Chainlink
The dominant oracle network. ~1000+ price feeds across EVM chains.
How it works:
- Multiple independent oracle nodes fetch prices from CEXes and DEXes
- Each node submits its observation to the aggregator contract
- The contract takes the median of all observations
- Updates when: deviation > threshold (typically 0.5–1%) OR heartbeat time passes
Reading a Chainlink feed on-chain:
// ETH/USD on Ethereum: 0x5f4eC3Df9cbd43714FE2740f5E3616155c5b8419
// SPA/USD on Arbitrum: Available via Chainlink
function getPrice() {
(, int256 price,,,) = priceFeed.latestRoundData();
return uint256(price); // 8 decimals
}Key feeds:
| Feed | Address (Ethereum) | Decimals |
|---|---|---|
| ETH/USD | 0x5f4eC3Df9cbd43714FE2740f5E3616155c5b8419 | 8 |
| BTC/USD | 0xF4030086522a5bEEa4988F8cA5B36dbC97BeE88c | 8 |
| USDC/USD | 0x8fFfFfd4AfB6115b954Bd326cbe7B4BA576818f6 | 8 |
Sperax Context: USDs uses Chainlink price feeds via its MasterPriceOracle to value collateral (USDC, USDT) and maintain its peg.
Pyth Network
Pull oracle — prices update sub-second but consumers must "pull" the latest update on-chain.
GET https://hermes.pyth.network/api/latest_price_feeds?ids[]=0xff61491a931112ddf1bd8147cd1b641375f79f5825126d665480874634fd0ace
Returns: { price: "6452345000000", expo: -8, conf: "2500000" }Chainlink vs Pyth
| Feature | Chainlink | Pyth |
|---|---|---|
| Model | Push (auto-updates) | Pull (consumer requests) |
| Latency | 1–60 min heartbeat | ~400ms |
| Cost | Gas paid by oracle network | Gas paid by consumer |
| Coverage | 1000+ feeds | 500+ feeds |
| Security | Battle-tested (5+ years) | Newer but growing fast |
Layer 3: Free Aggregator APIs
These combine CEX + DEX + oracle data into convenient APIs.

DeFi Llama (Best Free Option)
Zero rate limiting. Zero API key. Most generous free API in crypto.
| Endpoint | What It Returns |
|---|---|
coins.llama.fi/prices/current/{coins} | Current prices for any token |
api.llama.fi/protocols | All tracked protocols with TVL |
yields.llama.fi/pools | All yield pools across DeFi |
stablecoins.llama.fi/stablecoins | All stablecoin market data |
Price query example:
GET https://coins.llama.fi/prices/current/arbitrum:0xD74f5255D557944cf7Dd0E45FF521520002D5748
Returns: USDs price from on-chain sourcesCoinCap
Simple, clean API for top 2000 coins.
GET https://api.coincap.io/v2/assets?limit=10
Returns: Top 10 coins by market cap with price, volume, changeCoinPaprika
Decent free tier with ATH data and social links.
GET https://api.coinpaprika.com/v1/tickers/btc-bitcoin
Returns: Price, ATH, ATH date, volume, market cap, beta, supplyCryptoCompare
Good for OHLCV (candlestick) data.
GET https://min-api.cryptocompare.com/data/v2/histoday?fsym=BTC&tsym=USD&limit=30
Returns: 30 days of daily OHLCV dataBuilding Without CoinGecko
A practical multi-source approach:
| Data Need | Primary Source | Fallback |
|---|---|---|
| Top coin prices | Binance API | CoinCap |
| Long-tail tokens | DexScreener | DeFi Llama |
| Historical OHLCV | CryptoCompare | Binance klines |
| TVL / protocol data | DeFi Llama | — (only source) |
| Yield / APY data | DeFi Llama yields | — |
| On-chain accurate price | Chainlink feeds | Pyth |
| Token metadata | CoinPaprika | Token Lists |
| Market sentiment | Fear & Greed API | — |
Waterfall strategy (what production apps use):
1. Try Binance (fastest, most liquid)
2. Fall back to CoinCap (broader coverage)
3. Fall back to DexScreener (on-chain tokens)
4. Fall back to DeFi Llama (universal)SperaxOS uses a similar multi-provider waterfall: Binance → CoinCap → DexScreener → CoinGecko for maximum reliability.
Price Calculation Methods
VWAP (Volume-Weighted Average Price)
How aggregators compute a single price from multiple exchanges:
VWAP = Σ(Price_i × Volume_i) / Σ(Volume_i)Example:
| Exchange | Price | 24h Volume |
|---|---|---|
| Binance | $3,200 | $2B |
| Coinbase | $3,205 | $500M |
| Kraken | $3,198 | $100M |
VWAP = (3200×2B + 3205×500M + 3198×100M) / (2B + 500M + 100M)
= $3,200.96TWAP (Time-Weighted Average Price)
Used by Uniswap V3 oracle and some protocols:
TWAP = Average price over a time window (e.g., last 30 minutes)More resistant to manipulation than spot price.
Agent Tips
- Never rely on a single source — always implement fallbacks
- CEX data is freshest for major tokens — use Binance/Coinbase first
- DEX data is essential for tokens not listed on CEXes
- DeFi Llama is the best free API — zero rate limiting, comprehensive
- Chainlink feeds are the gold standard for on-chain price verification
- Always show the data source — users should know where prices come from
