⚡ Buy pump.fun coins for 0.4%
Paste a coin's address on /check, or open /buy/<coin address>.
How it works
- pumpdata builds the pump.fun trade: on the bonding curve, or on PumpSwap after graduation.
- Your wallet shows it and you sign. We never hold your key or your funds; no account, no deposit.
- Our fee, 0.4% of the SOL side, is a transfer inside that same transaction: if the trade doesn't land, there is no fee.
Why it costs less
| where | fee | notes |
|---|---|---|
| pumpdata | 0.4% | every trade size; no minimum, no account, your own wallet |
| fomo | 0.50% | 0.45% for referred users; on Solana, 2% on $5-47.50 trades and a $0.95 minimum up to $190 (fomo publishes no schedule; third-party fee guides) |
| Axiom | 0.5% to 1% | 2026 guides disagree (0.5%, 0.7%, 1%) |
| Photon | up to 1% | guides give 0.25% to 1% |
| GMGN | 1% | less with a referral code |
| Trojan | 0.9% to 1% | Telegram bot |
Other venues' fees as their pages or fee guides state them, read Nov 9, 2026; a venue that changes its fee is corrected here.
For bots and agents: the API

Free, no key.POST /buy {"mint","sol","wallet"}(andPOST /sell {"mint","tokens" (raw units), "all" or a share such as "50%","wallet"}): an unsigned transaction. Options:slippage_bps(default 1000, at most 2500),priority(micro-lamports per compute unit, default 200,000),tip_lamports(a Jito tip).- Sign it and send it yourself, or
POST /send {"tx"}: we send it to the network and Jito at once and answer with the signature and whether it landed.
Every coin answer (/check/<mint>.json, the launch feed, the MCP tools) carries a buy field with these links.
Memecoins mostly go to zero; this page is a tool, not advice. pumpdata reads pump.fun's public on-chain programs; it is not pump.fun. Terms for trades.
