# Bitquery Docs

> Bitquery is a blockchain data platform for builders who need trades, prices, and history
> without running their own nodes. Query or stream data across 40+ chains through GraphQL,
> WebSocket, Kafka, and Solana gRPC — or ask in plain English via the MCP server for AI agents.

## Start here

- [**Bitquery in one page**](https://docs.bitquery.io/docs/start/bitquery-for-ai/) — the whole API as one self-contained page: endpoints, chains, cubes, datasets, rules and worked queries. Written to be pasted into an AI assistant's context. Raw markdown: https://docs.bitquery.io/docs/start/bitquery-for-ai/index.md
- [Docs home](https://docs.bitquery.io/) — platform overview and navigation
- [GraphQL IDE](https://ide.bitquery.io/) — run queries in the browser, no setup
- [First query in 5 minutes](https://docs.bitquery.io/docs/start/first-query/)
- [API keys & authentication](https://docs.bitquery.io/docs/authorization/how-to-generate/)
- [Starter queries](https://docs.bitquery.io/docs/start/starter-queries/) — tested queries by chain and data type, the same tree the IDE shows
- [Starter subscriptions](https://docs.bitquery.io/docs/start/starter-subscriptions/) — the real-time half of the same tree
- [MCP Server for AI agents](https://docs.bitquery.io/docs/mcp/mcp-server/)

## Endpoints, chains and datasets

Two generations of the API, with different schemas. Sending a query to the wrong one is the
most common mistake.

- **V2** — `https://streaming.bitquery.io/graphql`, and `wss://` for subscriptions. Covers
  Ethereum, BSC, Base, Arbitrum, Optimism, Polygon, Robinhood Chain, Solana, Tron and
  Hyperliquid. Roots are capitalised: `EVM`, `Solana`, `Tron`, `Trading`.
- **V1** — `https://graphql.bitquery.io`. Everything else: Bitcoin, Litecoin, Bitcoin Cash,
  Dogecoin, Dash, Zcash, Cardano, Ripple, Stellar, Algorand, Filecoin, Avalanche, Celo,
  Cronos, Klaytn, Fantom, Moonbeam. Roots are lowercase: `bitcoin(network:)`,
  `ethereum(network:)`, `stellar(network:)`, `filecoin(network:)`.
- Ethereum, BSC, Tron and Polygon are **migrating off V1** — query them on V2.
- Every V2 root takes `dataset:` — `realtime` (default, recent window only), `archive` (full
  history), `combined` (both). Archive and combined need the historical data add-on.

- [Dataset options](https://docs.bitquery.io/docs/graphql/dataset/options/) — realtime vs archive vs combined
- [Archive dataset](https://docs.bitquery.io/docs/graphql/dataset/archive/) — how to query history
- [Data coverage & retention](https://docs.bitquery.io/docs/graphql/data-coverage-retention/) — how far back each cube goes, per chain
- [Endpoints](https://docs.bitquery.io/docs/start/endpoints/) — regional hosts for V1 and V2

## Trading data — prices, trades & OHLCV

Most teams building charts, bots, or dashboards start here. The **Trading cube** gives you
clean, MEV-filtered swap data with USD price, market cap, and supply on every row.

- [Trading data overview](https://docs.bitquery.io/docs/trading/trading-data-overview/) — when to use Trading cube vs chain-level APIs
- [Crypto Trades API](https://docs.bitquery.io/docs/trading/crypto-trades-api/trades-api/) — real-time DEX swaps across 9 chains in one query
- [Crypto Price API](https://docs.bitquery.io/docs/trading/crypto-price-api/introduction/) — token prices, pairs, and aggregated feeds
- [OHLC / candlestick (K-line) API](https://docs.bitquery.io/docs/trading/crypto-price-api/crypto-ohlc-candle-k-line-api/) — build charts and technical indicators
- [Market cap & supply fields](https://docs.bitquery.io/docs/trading/crypto-price-api/crypto-marketcap-api/) — FDV, circulating supply on trade rows
- [Traders API](https://docs.bitquery.io/docs/trading/crypto-trades-api/traders-api/) — wallet-level trade history and PnL-style analytics

For **historical OHLC older than ~30 days**, use chain-level [`DEXTradeByTokens`](https://docs.bitquery.io/docs/cubes/dextradesbyTokens) instead of the Trading cube.

## Historical data & bulk uploads

Need a full backfill, data lake, or warehouse load — not row-by-row GraphQL?

- [Cloud datasets overview](https://docs.bitquery.io/docs/cloud/) — Parquet exports to S3, GCS, Snowflake, BigQuery
- [EVM historical dumps](https://docs.bitquery.io/docs/cloud/evm/) — Ethereum, Polygon, Base, and other EVM chains
- [Solana historical dumps](https://docs.bitquery.io/docs/cloud/solana/)
- [BSC / BNB Chain dumps](https://docs.bitquery.io/docs/cloud/bsc/)
- [Sample data on GitHub](https://github.com/bitquery/blockchain-cloud-data-dump-sample) — explore schemas before you buy

## Solana launchpads and memecoins

The most asked-about area. The IDE's Solana section carries ~15 Pump.fun
queries and ~15 Pump.fun streams, plus Raydium, Meteora and LetsBonk.fun — new
token creation, bonding curve progress, graduation to PumpSwap, ATH market cap,
top traders, creator fees, and first-buyer/sniper detection.

- [Pump.fun API product page](https://bitquery.io/products/pumpfun-api) — delivery channels (GraphQL, WebSocket, gRPC, Kafka), latency, pricing, free trial
- [Pump.fun market cap & bonding curve](https://docs.bitquery.io/docs/blockchain/Solana/Pumpfun/Pump-Fun-Marketcap-Bonding-Curve-API/) — graduation progress
