pumpdata.funGet a free key

The pump.fun stream: every launch and trade, live

In short

A WebSocket that sends every pump.fun create, bonding-curve and PumpSwap trade, curve completion and migration about 1.5 seconds after its block (1.5 s median, 1.8 s p90, measured Nov 7), unmetered: no credits, no per-message billing. The pro tier adds each new coin's deployer record (launches before it, graduations, the gap since the last one) a few seconds after the create. 7-day free trial on a free key.

Start

  1. Get a free key at /keys.
  2. Start the trial: curl -X POST https://pumpdata.fun/stream/trial -H "x-api-key: pdk_..."
  3. Connect: wss://pumpdata.fun/stream?key=pdk_...&types=create,trade,complete,migrate,record&min_sol=1

What it sends

  • create: mint, deployer, name, symbol, slot, idx, ts
  • trade: venue (curve or pumpswap), mint, pool, wallet, side, sol, token_amount; a PumpSwap pool quoted in another token carries quote_mint, quote_amount instead of sol
  • complete: the curve emptied (mint, wallet); migrate: moved to its PumpSwap pool (mint, pool)
  • record (pro): mint, deployer, deployer_launches_before, deployer_graduations_before, deployer_gap_s, deployer_launches_last_day

Filters in the URL: types (default create, complete, migrate; trades are about 200 a second, so add min_sol or mints), min_sol for trades, mints (up to 200, comma separated). A client that falls more than a few seconds behind is disconnected rather than buffered: filter, and reconnect on close.

Example (Python)

import asyncio, json, websockets
URL = "wss://pumpdata.fun/stream?key=pdk_...&types=create,record"
async def main():
    async for ws in websockets.connect(URL):
        try:
            async for msg in ws:
                ev = json.loads(msg)
                if ev["type"] == "record" and ev["deployer_launches_before"] > 50:
                    print("serial deployer", ev["deployer"], ev["mint"])
        except websockets.ConnectionClosed:
            continue
asyncio.run(main())

After the trial

$199 a month for one connection or $499 a month for up to five, both with the deployer records, paid by card or in USDC. Tell us what you are building: the stream is new and we are shaping it with its first users.

Opens your order: pay by card (monthly, cancel any time) or in USDC on Solana (one month). The month starts when it is paid, after any days the key already has. From a script: curl -X POST https://pumpdata.fun/stream/buy -H "x-api-key: pdk_..." -H "content-type: application/json" -d '{"plan":"one"}'

Data: the recorder's own read of the chain (the same files behind every pumpdata.fun answer). No guarantee of completeness during a stream outage; the recorder's gaps are listed on /status.
