How this industry works
Every other page here answers “which tool”. These answer the questions that decide whether the answer is usable at all — what an exchange charges for its own prices, who owns the identifier on a security, what an index licence covers. Reference pages, corrected in place rather than dated, each one cited.

What happens to a pair's data when an exchange delists it
Whether a bot can see a delisting coming, what the API says afterwards, where the history goes, and why the pair drops out of a backtest universe.

What it costs to get a coin listed on CoinGecko and CoinMarketCap

What your exchange API key lets a trading bot do
A bot can do what the exchange key allows, from where the key allows it. How Binance, OKX, Coinbase and Bybit split permissions, and what IP binding changes.

A Binance chart is live at no charge; CME bitcoin futures lag by ten minutes unless you pay. Who sets that fee, who is professional, and what bots owe.

How a crypto index is built
What decides which coins get into a crypto index, which exchanges price them, how weights are capped and rebalanced, and why the name needs a licence.

Credit, request, weight, symbol: why API quotas don't compare
Crypto data APIs meter weight, calls, data points, assets, compute or instruments, so one job costs a different number on each. How to convert it.

What an Ethereum RPC endpoint cannot answer
The eth_ namespace is one half of Ethereum. Staking, proposer pay, private order flow and smart-account users sit outside it, and so does some of the ETH.

Where an on-chain number comes from before you see it
Four stages sit between a block and a dashboard — a node, an indexer, an attribution layer and a metric definition. Each one is a decision you cannot see.

Why this market won't quote you a price
Two products in five publish no price for at least one tier. What sets the fee when no list exists, where the silence falls, and what to ask before a demo.

What exchange API terms actually let you do
Public crypto endpoints answer without a key. The terms behind them still restrict redistribution, benchmarks and model training, and name an unpriced licence.
