pumpfun-creator-fees

Look up Pump.fun creator-reward earnings by coin mint, wallet address, or username.

Single-page web app with a JSON API. Live data, no mocks. Deploys to Vercel.

What it shows

Given any of the three inputs, returns:

• Total earned (lifetime, in SOL + USD)
• Claimed (already withdrawn by the creator)
• Unclaimed (sitting in the fee-sharing vault)
• Per-coin breakdown — every coin currently sharing fees with the resolved wallet, with image, market cap, and share basis points

When the input is a coin mint, it also shows the creator's all-coin totals for context.

Data sources

This is a thin proxy over Pump.fun's own public-but-undocumented APIs:

• https://swap-api.pump.fun/v1/fee-sharing/account/{wallet}/totals — earnings (with optional ?mint= filter)
• https://swap-api.pump.fun/v1/fee-sharing/account/{wallet}/shares — per-coin sharing config
• https://frontend-api-v3.pump.fun/coins-v2/{mint} — coin metadata + creator
• https://frontend-api-v3.pump.fun/users/{username|wallet} — username → wallet

These are the same endpoints the live pump.fun frontend calls. Not affiliated with Pump.fun.
