token_get_candles({ chain: "solana", tokenAddress: "TOKEN_ADDRESS", resolution: "1m" })
How do I track Pump.fun tokens about to graduate? Tokens in the “final stretch” are close to meeting the bonding curve graduation threshold and migrating to Raydium.
curl "https://api.chainstream.io/v2/ranking/sol/finalStretch" \ -H "X-API-KEY: your_api_key"
See Ranking - Final Stretch for full reference. ranking_get_final_stretch({ chain: "solana" })
How do I find tokens that graduated from Pump.fun? Graduated tokens have completed the bonding curve and migrated to a Raydium liquidity pool.
curl "https://api.chainstream.io/v2/ranking/sol/migrated" \ -H "X-API-KEY: your_api_key"
See Ranking - Migrated for full reference. ranking_get_migrated({ chain: "solana" })
How do I get the top traders for a Pump.fun token? REST API
GraphQL
MCP Tool
curl "https://api.chainstream.io/v2/trade/sol/top-traders?tokenAddress=TOKEN_ADDRESS" \ -H "X-API-KEY: your_api_key"
See Trade - Top Traders for full reference. query { DEXTrades ( network : sol limit : { count : 100 } tokenAddress : { is : "TOKEN_ADDRESS" } where : { IsSuspect : { eq : false }} ) { Trade { Buy { Account { Owner } Amount PriceInUSD } } count sum ( of : Trade_Buy_Amount ) } }
trade_get_top_traders({ chain: "solana", tokenAddress: "TOKEN_ADDRESS" })
How do I check a Pump.fun token’s security? curl "https://api.chainstream.io/v2/token/sol/TOKEN_ADDRESS/security" \ -H "X-API-KEY: your_api_key"
See Token - Security for full reference. token_get_security({ chain: "solana", tokenAddress: "TOKEN_ADDRESS" })
How do I create a token on Pump.fun? ChainStream supports creating tokens on Pump.fun directly via API.
curl -X POST "https://api.chainstream.io/v2/dex/sol/create" \ -H "X-API-KEY: your_api_key" \ -H "Content-Type: application/json" \ -d '{ "launchpad": "pumpfun", "name": "My Token", "symbol": "MYTKN", "description": "A test token", "privateKey": "YOUR_PRIVATE_KEY" }'
See DEX - Create for full reference. pumpfun_create({ name: "My Token", symbol: "MYTKN", description: "A test token" })
Token creation requires a funded Solana wallet. The private key is used to sign the creation transaction.
How do I get the developer’s other tokens? Find all tokens created by a specific developer address on Solana.
curl "https://api.chainstream.io/v2/token/sol/dev/DEV_ADDRESS/tokens" \ -H "X-API-KEY: your_api_key"
See Token - Dev Tokens for full reference. token_dev_get_tokens({ chain: "solana", devAddress: "DEV_ADDRESS" })
FAQ
What is Pump.fun graduation?
When a Pump.fun token’s bonding curve reaches 100%, it “graduates” — the liquidity is migrated to a Raydium pool and the token begins trading on the open market. Use the ranking/sol/finalStretch endpoint to track tokens approaching graduation, and ranking/sol/migrated for tokens that have already graduated.
How do I filter out bot/MEV trades?
The GraphQL DEXTrades Cube has a default filter IsSuspect = false that automatically excludes suspected bot and MEV trades. For REST API, check the trade response for the isSuspect field.
Can I track Pump.fun tokens in real time?
Yes. Use WebSocket subscriptions for real-time price updates and trade streams. See Real-time Streaming for setup instructions.
Which chains support Pump.fun?
Pump.fun is a Solana-only launchpad. Use chain: sol (REST) or network: sol (GraphQL) for all Pump.fun queries.
