## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability crewpay-agent-launch-unsigned-transaction-b5a47767 -d '<json body>'
```

Example prompt: Launch a new meme coin called 'MoonCat' with ticker $MCAT on Pump.fun using my wallet ABC123, auto-hire 3 KOL seats, use this image https://example.com/mooncat.png, and set an initial buy of 0.5 SOL — the vibe is 'the internet's favorite cat, now on-chain'.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
