Pulse: new token launches
Fresh launches, curves close to graduating and fresh graduations: views, filters, naming, and what is not provided.
Launches as they happen: fresh launches, bonding curves close to graduating, and fresh graduations, with filters and sorting. Read a snapshot over REST, or follow a list with the pulse channel.
Pulse is a chain's board of launches: tokens a launchpad just created, bonding curves close to graduating, and curves that just graduated. Read a snapshot with GET /chains/:chain/pulse, or follow a list with the pulse channel.
Views
| View | Holds | Board |
|---|---|---|
new | Launches that have not graduated | The newest 1,000 of the last 24 h |
graduating | Open bonding curves that traded in the last hour | The 500 with the highest progress |
graduated | Curves that completed in the last 24 h | The newest 500 |
A launch is recorded only from a launchpad's own creation event, such as pump.fun's on Solana and four.meme's on BSC.
Filters
Filters are query parameters (on the socket, parameters of the subscribe message), and a token must match all of them. Filtering, sorting and paging run over the view's board.
| Parameter | Keeps | Example |
|---|---|---|
<key>=<min>..<max> | Values in the range, bounds included. Either side may be empty. A null value never matches. | marketCapUsd=5000.., progress=..0.9, age=60..600 |
launchpad=a,b | Any of them | launchpad=pumpfun |
has=a,b | Every one of them: logo, website, twitter, telegram, discord | has=logo,twitter |
keywords=a,b | The symbol or name contains any of them, case-insensitive | keywords=cat,dog |
excludeKeywords=a,b | The symbol or name contains none of them | excludeKeywords=test |
sort=<key> | Any range key, or createdAt, graduatedAt, latestTradeAt. By default createdAt (new), progress (graduating), graduatedAt (graduated) | sort=windows.1h.volumeUsd |
order=desc or asc | desc by default. Nulls sort last either way; ties break by address, ascending | order=asc |
limit, offset | limit 1–100 (50 by default), offset 0 or more. total counts every match | limit=20&offset=20 |
Range keys: priceUsd, marketCapUsd, liquidityUsd, progress, age, creatorNetShare, sniperCount, sniperNetShare, and windows.<w>.<m>, where <w> is 5m, 1h, 6h or 24h and <m> is one of priceChange, volumeUsd, buyVolumeUsd, sellVolumeUsd, trades, buys, sells, traders, buyers, sellers, feesPaidUsd.
Examples:
# pump.fun launches under 10 minutes old, with a logo and a Twitter link
https://app.aurelia.build/api/chains/solana/pulse?launchpad=pumpfun&age=..600&has=logo,twitter
# curves at least 80% sold that traded over $5k in the last hour, by that volume
https://app.aurelia.build/api/chains/solana/pulse?view=graduating&progress=0.8..&windows.1h.volumeUsd=5000..&sort=windows.1h.volumeUsd
# four.meme launches on BSC without "test" in the name, oldest first
https://app.aurelia.build/api/chains/evm:56/pulse?launchpad=fourmeme&excludeKeywords=test&order=ascLaunchpads: fourmeme, flap and genius on BSC; pumpfun, letsbonk, raydium-launchlab and meteora-dbc on Solana; doppler, zora, clanker, virtuals, o1, basestonk, flaunch and rwagmi on Base; flap, doppler, pons, pools-trade, torch and frontier on Robinhood Chain; clanker and stockereum on Ethereum. An unknown parameter, a malformed range, an unknown view or a malformed launchpad id answers 400, and the error names the parameter.
Not provided on the board
- Holder counts and top holdings: token holders answers them one token at a time.
- Snipers here are by swaps only: wallets that bought in the launch block or the 4 after it. Wallet labels (insider, sniper) follow their own rules across launches.
