Pump.fun API

Quick answer

pump data is a pump.fun API with every pump.fun trade, ever: a deployer's whole launch record, a coin's bundle and how launches like it went, any wallet's record, and base rates by market cap. Five calls an hour are free with a key; past that it is half a cent a call over x402, with no account.

Start in a minute

Get a free key at pumpdata.fun/keys (one email, one link).
Send it as a header on any call:

curl -H "x-api-key: pdk_..." https://pumpdata.fun/deployer/7ufmve7ZSFCzuNcKRunYrGtyb2Ka1MXzkWwf7jZhVsmL

Each answer says how many calls are left this hour (X-RateLimit-Remaining). Without a key, the same call answers 402 with its price; pay it over x402 and send it again.

The calls

Call	What it answers	Price past the free tier
`GET /deployer/{address}`	A dev's whole launch record and how their recent launches went	$0.005
`GET /launch/{mint}`	One coin: its deployer, the bundle at creation, insiders, and how launches like it did over 24 h	$0.005
`GET /similar/{mint}`	The past launches most like this one, by address, and what each did next	$0.005
`POST /wallets`	Up to 50 wallets: winner, bot, supply seller or new, with PnL in SOL	$0.01
`GET /baserate`	Of the coins that crossed a market-cap band, the share that reached 2x, 5x, 10x, 20x	$0.005
`POST /replay`	Your picks run against the chain's history (always paid)	$2

MCP

The same calls are MCP tools at https://pumpdata.fun/mcp (Streamable HTTP). Send your key as the x-api-key header on the MCP request, or pay a tool per call. The stats tool, yesterday on pump.fun, is free.

Paying past the free tier

Every call is an x402 resource: a call without payment answers 402 with the price, the payee and the network (USDC on Solana); an x402 client pays and sends it again. No account, no invoice. The full contract is at /openapi.json, and a plain-text overview for agents at /llms.txt.

Free without a key

Yesterday on pump.fun at /stats, the daily card at /today, the record at /record, the daily wire at /report, and the research at /research.

Questions

How much does the pump.fun API cost?

Five calls an hour are free with a key. Past that, a call costs $0.005 ($0.01 for up to 50 wallets), paid per call in USDC on Solana over x402, with no account. A /replay run is always paid, $2.

Do I need an API key?

No. Any call can be paid per call over x402 without a key or an account. A free key, bound to your email, gives five lookup calls an hour without paying.

Can I look up a pump.fun dev's history?

Yes. GET /deployer/{address} returns every launch the wallet made, its graduations, its best peak, and how its launches of the last 90 days went: doubled, 10x, held 2x a day later, or dead.

Does it include dead coins?

Yes. Every pump.fun trade, ever, with the coins that died kept in. Base rates and launch matches count the dead ones.

Is it real time?

No. It is history for decisions: the tables are rebuilt daily, and launches since the last build come from a live recorder filled in hourly. Every answer carries X-Data-As-Of. For live prices use a price feed.

Can I trade or launch coins with it?

No. It reads history and never places trades or launches coins. For that you need a trading API.

Is this pump.fun's official API?

No. pump data is independent and not affiliated with pump.fun. It reads pump.fun's trades from the Solana ledger.
