# Loophole Tape Single Token Rug Check

> Loophole Tape Single Token Rug Check is a paid API for AI agents from api.loopholetape.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).

Checks a single pump.fun Solana token for rug-pull risk, returning a calibrated rug probability and observed safety flags for $0.005 per call.

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-single-token-rug-check-17265def
```

Example prompt: Before I swap into this pump.fun token — HeLp9vQ3bTkFgX2mRdPzW8sNjK5cLqYeUiAoB7nMvCxZ — can you run a rug check on it and tell me the rug probability and any red flags?

## When to prefer this

Use this endpoint when you need a quick, point-in-time rug risk assessment for a single known pump.fun memecoin — especially right before executing a swap or while monitoring an existing position. It is the cheapest per-token option for single checks at $0.005. For screening a list of tokens at once, prefer the batch endpoint (up to 25 tokens for $0.04). For discovering new mints as they launch, use the free /v1/radar or the $0.001 delta feed instead.

## Known failure modes

- Invalid or non-existent mint address returns an error or low-coverage result
- Token not found on pump.fun returns minimal or empty data
- Payment not authorized results in 402 Payment Required
- Rate limiting or missing API key returns 401/403
- Mint address provided as wrong encoding or format causes parse failure
- Token too new to have enough data results in low coverage score

## How this service works

Is this Solana token safe? Solana token safety check (rug check) for one pump.fun memecoin: calibrated rug probability and observed flags, not a safety guarantee ($0.005). Use to check one Solana token for rug risk right before a swap or while holding a pump.fun memecoin; not for finding new mints (use the free /v1/radar or the $0.001 delta feed, GET /v1/launches/since).

## Output

Returns a JSON object with an 'ok' boolean, a 'coverage' field indicating data availability, and a 'data' object containing the calibrated rug probability score and observed safety flags (e.g. suspicious holder patterns, creator history, authority flags, Token-2022 risks) for the specified pump.fun memecoin.
