Enhanced Stream
The PumpFun API for real-time Solana token launches, trades, and graduations
Pump.fun is the busiest memecoin pipe on Solana. Millions of trades a day across thousands of bonding curves, with graduations migrating tokens into PumpSwap and Raydium CPMM. The way most third-party APIs handle this is REST plus polling, which is slow enough that by the time you see a new token, the price has 4x'd. We push every Pump.fun event to your app the moment it lands: token creations, buys, sells, graduations, and the MEV-relevant transaction metadata (compute budget, priority fee, Jito tip). One gRPC connection. JSON or Protobuf, your choice.

Token creations
CreateEntrytopic = prod.rpc.solana.pumpfun.create
Fires every time a new token is launched on Pump.fun. Includes the mint, the bonding curve, the creator wallet, the initial reserves, and the metadata URI, everything a sniper needs to size and submit a buy in the next slot.

nln.stream.v1.StreamService/SubscribeWhat teams build on this stream
Sniper bots
Subscribe to the create topic and act on new mints in the next slot. The decoded payload includes the bonding curve, initial reserves, and the creator wallet, which is enough to size and submit a Jito-bundled buy without a separate getMint round-trip. The latency budget is mostly your code.
Copy trading
Filter the trade topic by leader-trader wallet and replicate sized buys and sells in the next slot. Real-time delivery keeps most of the alpha intact even on volatile memecoin pairs.
MEV & priority-fee analytics
The transaction topic surfaces compute-unit price, priority fee, and Jito tip on every Pump.fun transaction. Drives block-builder pricing, anti-frontrun logic, and the gas-burn dashboards your CFO actually wants.
Graduation alerts
Subscribe to the graduate topic and pair with the PumpSwap stream to capture both legs of a migration in the same transaction. The most-watched signal in memecoin trading.
Pricing, and where we sit vs the rest
The Pump.fun data market splits three ways. PumpPortal sells per-message WebSocket. Cheap on a quiet day, expensive on a memecoin Tuesday. Bitquery sells GraphQL with deep historical queries. Best for analytics and post-hoc work; weaker for real-time decisioning. Shyft ships parsed gRPC streams that overlap with our coverage. We charge flat, $49/month for two streams and $199/month for twenty, with no per-event surcharge and explicit MEV-transaction coverage that the others don't have.
Pro covers most production sniper and copy-trading workloads. Ultra adds 30 hours per month of custom Geyser-plugin development time, useful for teams that want a custom decoder fused with the existing parsed streams. Full breakdown is on the pricing page.
Frequently asked questions
Every Pump.fun event on Solana, pushed to your app the moment it lands on chain. Token creations, trades, bonding-curve graduations, and MEV-relevant transaction metadata. One gRPC connection. Decoded structures, not raw logs.
You get the token mint, name, symbol, creator wallet, and bonding-curve reserves the instant the create instruction lands. Fast enough to size and submit a buy in the next slot, which is what every serious sniper bot needs.
Yes, and it's one of the most common things people build with us. The create topic surfaces the mint, bonding curve, and initial reserves before any aggregator catches up. Several production bot operators run on us for the latency, the flat-rate pricing, and the fact that there's no per-event meter that goes ugly when memecoin Tuesday hits.
Four topics cover the full lifecycle: prod.rpc.solana.pumpfun.create (new token launches with metadata), .trade (every buy and sell on the bonding curve), .graduate (when a token completes its curve and migrates to PumpSwap or Raydium), and .transaction (compute budget, priority fee, Jito tip, and the MEV-relevant transaction metadata). Subscribe to any combination.
Both. format=1 returns JSON, format=2 returns Protobuf. Same stream, same fields, your call. JSON for debugging and scripting; Protobuf when you're optimizing throughput in production.
PumpPortal: per-message WebSocket. Easy to start, costs spike during memecoin peaks. Bitquery: GraphQL with deep historical queries. Excellent for analytics, less suited to real-time decisioning. Shyft: gRPC streams that overlap with our coverage. We charge flat ($49/month for 2, $199/month for 20), no per-event meter, plus explicit MEV-transaction coverage that the others don't have.
JavaScript, Python, Rust, Go, anything with gRPC support. Code samples for each are above. Most developers are streaming live Pump.fun data inside five minutes of getting their API key.
Subscribe to prod.rpc.solana.pumpfun.graduate. Each event has the token mint, the new pool address (PumpSwap or Raydium CPMM), the migrated SOL and token amounts, and the migration fee. Use it to trigger alerts, provide post-graduation liquidity, or hedge. The companion PumpSwap stream catches the create_pool instruction that fires in the same transaction.
Pro ($49/month, 2 concurrent streams) and Ultra ($199/month, 20 concurrent streams). The free tier includes RPC, WebSocket, and gRPC node access but no parsed streams. Sign up free to validate the connection, upgrade when you're ready to stream.
