How this service works
Live rug checks for new pump.fun memecoins on Solana (calibrated rug probability and graduation odds, holders, creator record, rug flags) and Robinhood Chain pons launch and token risk cards, computed in real time from our own independent capture of every on-chain event (not resold third-party data). Pay per request in USDC on Solana or Base through x402 with no account: $0.001-$0.04 per data call, $5.00 per daily dataset file; prepaid keys ($0.10 trial, $2.00) serve clients without an x402 library. Responses report coverage, freshness and observed evidence.
Output
Returns a JSON object with the mint address, a ranked list of up to N holders (each with rank, wallet address, balance share, and wallet labels like 'bundle'), total holder count, and concentration metrics including HHI, top-5 share, and top-10 share. Also includes a coverage field indicating data completeness and freshness.
Example use cases
Pre-buy rug sniff on new launch
“Before I ape into this pump.fun token at 73sfnFgqQzpSRZSimCC4sxpubqghRGYewYLmiUH2pump, pull the holder distribution for me — I want to see the top holders, their share of supply, and whether any wallets are flagged as bundles.”
Automated memecoin screener concentration filter
“I'm screening new pump.fun launches and want to automatically skip any coin where the top 10 wallets hold more than 40% of supply — can you pull the holder concentration data for mint 73sfnFgqQzpSRZSimCC4sxpubqghRGYewYLmiUH2pump so I can check?”
Research whale dominance in a trending token
“This pump.fun token is trending but I want to know if it's just a few wallets pumping it — pull the holder list for mint 73sfnFgqQzpSRZSimCC4sxpubqghRGYewYLmiUH2pump and tell me the HHI score and what share the top 5 addresses own.”
Technical details
Endpoint
GEThttps://api.loopholetape.com/v1/mint/%7Bmint%7D/holders?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, independently captured holder distribution data for a specific pump.fun memecoin — especially to detect bundle wallets, whale concentration, or suspicious ownership patterns before trading. Prefer this over generic on-chain explorers when you need labeled wallet classifications (e.g. 'bundle') and calibrated concentration metrics like HHI computed from live event capture rather than resold third-party snapshots.
Side effects
- Mint address not covered — endpoint may return partial or no data; recommend calling /v1/check/coverage first
- Invalid mint address format (must match base58 pattern 32–44 chars) returns a validation error
- Unpaid or insufficient USDC balance via x402 causes a 402 Payment Required response
- Token is too new and on-chain events have not been fully indexed yet — coverage field will indicate 'partial'
- Rate limiting or network errors from Solana RPC may delay real-time data ingestion
