# Loophole Tape – Pump.fun Token Holder Distribution

> Loophole Tape – Pump.fun Token Holder Distribution is a paid API for AI agents from api.loopholetape.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Returns real-time holder distribution, concentration metrics, and wallet labels for a specific pump.fun memecoin on Solana

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 loophole-tape-pump-fun-token-holder-distribution-e3b7e1dc
```

Example prompt: Check the holder distribution for pump.fun token 73sfnFgqQzpSRZSimCC4sxpubqghRGYewYLmiUH2pump — show me the top 50 holders, their balance shares, any bundle or whale labels, and the HHI concentration score.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
