How this service works
Production Pump.fun fee desk on Solana mainnet. AI agents hire KOLs with permanent on-chain fee-shares (60% KOLs · 15% agent · 25% CrewPay treasury). Buyback cron not live yet.
Output
Returns a JSON object with ok:true, a base64-encoded unsigned transaction to be signed locally, step-by-step signing instructions (sign then POST to /api/agent/launch/submit), a human-readable fee map (60% KOLs, 15% agent, 25% treasury), and the target platform name. The private key never leaves the client.
Example use cases
Meme coin launch with hand-picked KOL crew
“Launch a Solana meme coin called 'PepeDoge' ticker $PEPED on Pump.fun using my wallet XYZ789pubkey — I want to manually assign 3 specific KOL addresses with equal fee shares, use image https://mycdn.com/pepedoge.png, and kick things off with a 1 SOL initial buy. Description: 'The crossover nobody asked for but everyone needed.'”
Auto-hire KOL seats for new token
“Create a new Pump.fun token called 'RocketSloth' with ticker $RSLTH using launcher wallet MYWALLET111, automatically hire 5 KOL seats, add this image https://art.example.com/sloth.png, and describe it as 'slow gains, moon guaranteed' — start with 0.2 SOL initial buy.”
Multi-chain token launch on Zora
“Launch a coin called 'BasedBean' with ticker $BEAN on Zora, auto-hire 4 KOL seats, use image https://images.example.com/bean.gif, and set the description to 'the bean that launched a thousand memes' — my launcher wallet is ZORALAUNCH999.”
Technical details
Endpoint
POSThttps://api.crewpay.dev/api/agent/launch/unsigned?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to launch a meme coin on Pump.fun, Bags, or Zora with automatic on-chain KOL fee splits — particularly when you want AI agents to programmatically hire influencers and distribute revenue shares without manual coordination. Prefer this over generic token launch tools when permanent fee-sharing (60/15/25 split) and KOL management are requirements.
Side effects
- Missing launcherPubkey for pumpfun/bags platform causes validation error
- KOL crew shares not summing to 100 causes rejection
- imageUrl not publicly accessible or wrong format (non-PNG/JPEG/WebP/GIF) causes failure
- ticker or name exceeding character limits returns 400 validation error
- initialBuySol exceeding 10 SOL maximum causes rejection
- treasuryBps outside 2000-3000 range causes validation failure
- Unsigned transaction must still be submitted to /api/agent/launch/submit or coin is never created
