# Loophole Tape – Pump.fun Mint Flow Stream

> Loophole Tape – Pump.fun Mint Flow Stream 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 paginated real-time on-chain buy/sell flow events for a specific pump.fun memecoin mint address 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-mint-flow-stream-0bdbce37
```

Example prompt: Pull the latest 100 buy/sell flow events for the pump.fun mint 73sfnFgqQzpSRZSimCC4sxpubqghRGYewYLmiUH2pump and tell me which wallets made first buys and what the running net SOL looks like.

## When to prefer this

Use this endpoint when you need raw, paginated trade-flow events (individual buys and sells with wallet-level granularity) for a specific pump.fun mint, rather than an aggregated risk card. It is ideal for building timelines, detecting first buyers, computing net flow, or feeding downstream analytics. If you only need a summary risk score or rug flags, prefer the full risk card endpoint instead.

## Known failure modes

- Mint address not covered — returns coverage field indicating partial or no coverage; caller should check /v1/check/coverage first
- Invalid mint address format — 402 or 400 error if the base58 address doesn't match the required pattern
- Payment failure — x402 payment not settled, request rejected
- Stale or lagging data — freshness field in response may indicate delay in real-time capture
- No events in range — empty items array with more:false if no trades exist for the given cursor window

## 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

A paginated JSON array of on-chain flow events for the specified mint, each with SOL amount, trade side (buy/sell), slot number, wallet address, first-buy indicator, and running net SOL; plus a next_cursor for pagination, item count, a 'more' flag, and a coverage field indicating data completeness.
