You can even choose your confirmation probability:
•
'auto' / 'auto-95' → ~95% success (~0.015 SOL ≈ $3-4) •
'auto-75' → ~75% success (~0.00113 SOL ≈ $0.2-0.3) •
'auto-50' → ~50% success (~0.00022 SOL ≈ $0.04)⚠️ Note: During heavy network congestion, fees for ~75/95% success can rise significantly — even $10 per transaction.
💡 Don’t want to overspend?
Use minimal fee
0.00001 SOL + 'guaranteedDelivery': 'true' - we’ll retry your tx up to 5 times within 10 seconds.⚡️ Also new: optional
'jitoTip' parameter (e.g. jitoTip: 0.01). Min 0.01 SOL required to join Jito auctions.

This is our biggest update ever. It affects everyone and includes breaking changes.
⚡️ New Event Types
• Transfer events are here! Built with copy-traders in mind. We group all transfers in a transaction and send them in one convenient message. No trader can hide from you anymore! If you had your own implementation before - you can simplify your code now.
• createPool events for custom pools on Pump AMM / Raydium CPMM
• add/remove liquidity events
🔓 All Pools Unlocked
We now stream ALL events from Pump AMM, Raydium CPMM and Raydium Launchpad - including non-standard pairs like Token-USDC (without SOL).
💰 Trading API Improvements
• Minimum jitoTip reduced 5x → now just 0.0002 SOL
• Auto-split to Jito kicks in at 0.00023 SOL for manual fees
• New maxPriorityFee parameter - set a ceiling for auto-95 and other auto modes
• Smart pool selection - we automatically find the best and largest pool for any token. Need a specific pool? Just pass
poolId• Trade non-standard pairs using
quoteMint🛡 Scam Detection Fields
• poolCreatedBy - replaces mintMethod. Check if it equals
pump or raydium-launchpad (safe) vs custom (risky). This is your main filter now.• burnedLiquidity - shows % of liquidity that's permanently locked. Higher = safer. Pump.fun tokens burn 100% after migration, so no rug pulls possible.
• poolId added to every trade event. Use it for arbitrage or track SOL price from
Gf7sXMoP8iRw4iiXmJ1nq4vxcRycbGXy5RL8a8LnTd3v (large SOL-USDC pool) - no external API needed.📝 Naming Changes (Breaking)
•
traderPublicKey → txSigner (just the fee payer address)• tradersInvolved added to every event - shows actual accounts that sent/received funds. Use this for copy-trading, not txSigner!
•
Bonk → raydium-launchpad (Bonk is just one config of Raydium Launchpad)•
denominatedInSol → denominatedInQuote•
tokenExtensions now returns a dict instead of list🔧 Other Changes
• Added
platform field for raydium-launchpad events: bonk, raydium-launchlab or custom• Added
decimals to create events and getTokenInfo• Many bug fixes including missing migration events
Since this update has breaking changes, we released it on separate endpoints:
‣ Datastream → wss://test.stream.pumpapi.io/
‣ Trade API → https://test.api.pumpapi.io
Just add "test." to any our URL you're using.

You can now trade on Bags.FM, Moonshot, and other launchpads that are configs of Meteora Launchpad — directly via PumpAPI.
What is Meteora Launchpad?
Meteora Launchpad is a launchpad constructor (similar to Raydium Launchpad).
Its official name is Meteora Dynamic Bonding Curve.
A large share of trading volume is happening there right now.
⚠️ Mandatory: Track `lockedLiquidityAfterMigration`
If
lockedLiquidityAfterMigration is less than 100%, the creator will gain control over the unlocked part of liquidity after migration.New field: `launchpadConfig`
We added
launchpadConfig so you can easily detect which launchpad config a token belongs to and build better strategy filters.Support for the pools that tokens migrate into from Meteora Launchpad will be added soon.
