# Loophole Tape Watchlist Risk Check

> Loophole Tape Watchlist Risk Check is a paid API for AI agents from api.loopholetape.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Check a watchlist of Solana token mint addresses for real-time pump.fun/PumpSwap risk flags and suspicious on-chain behavior

## Facts

- Endpoint: GET https://api.loopholetape.com/v1/check/watchlist
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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-watchlist-risk-check-a6bff792
```

Example prompt: Can you run a watchlist risk check on these Solana token mints and tell me if any have a creator_sold flag or other red flags from independent on-chain data?

## When to prefer this

Choose this endpoint when you need independent, self-captured on-chain risk data for pump.fun or PumpSwap tokens rather than resold third-party feeds. It is especially useful for screening multiple token mints simultaneously via a watchlist, when you need real-time creator behavior signals (e.g. creator_sold), and when you want pay-per-request access with no API key via x402 on Solana or Base.

## Known failure modes

- Invalid or malformed mint address returns an error or empty findings
- No on-chain events captured yet for a newly launched token may yield incomplete coverage
- Rate limiting or payment failure via x402 protocol returns a payment-required error
- Token not listed on pump.fun or PumpSwap returns no coverage or partial results
- Network congestion on Solana may delay event capture, reducing freshness

## How this service works

Live pump.fun / PumpSwap risk checks and Robinhood Chain Pons V2 launch analytics, 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: no account, no API key, 0.5-2.5 cents per call. Responses report coverage, freshness and observed evidence.

## Output

Returns a JSON object with ok status, a count of checked items, an array of mint addresses each with their associated risk findings (e.g. creator_sold flag codes), an overall status field (e.g. flags_observed), and a coverage indicator reflecting data freshness and completeness.
