# IsThisARug PASS/FAIL Gate Pack

> IsThisARug PASS/FAIL Gate Pack is a paid API for AI agents from x402.isthisarug.trade, paid per call via x402, $0.005/call, status down (last checked 2026-10-19).

Runs a compact PASS/FAIL playbook of on-chain rug-risk gates (contract check, ERC20 validity, LP burn ≥90%, no EOA LP, no stub LP, sell-quote) for a given token contract address.

## 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 isthisarug-pass-fail-gate-pack-a4ad1548
```

Example prompt: Run the rug-risk gate pack on this token contract 0x1234567890abcdef1234567890abcdef12345678 on Base — I need to know if it passes LP burn, EOA LP, stub LP, and sell-quote checks before I buy.

## When to prefer this

Choose this endpoint when you need a fast, cheap (~$0.005) machine-readable PASS/FAIL verdict across a standardized set of rug-risk gates — specifically LP burn ≥90%, EOA LP absence, stub LP absence, and sell-quote validity — rather than a full narrative diligence report. Ideal for automated trading bots, token screeners, or pre-buy safety checks where a structured gate-by-gate verdict is more useful than prose. Use sibling endpoints if you need a fuller on-chain snapshot, X/Twitter identity matching, or a composite GO/NO_GO/WAIT decision.

## Known failure modes

- Invalid or malformed contract address (0x prefix or hex length wrong) returns an error
- Unknown or unsupported chain hint returns an error or defaults to Robinhood chain
- Contract address not found on specified chain returns a failure or empty result
- Token with no V2 pair detected may result in LP gate failures or incomplete data
- Network or RPC errors for the queried chain may cause timeouts or partial results

## How this service works

Compact PASS/FAIL playbook gate pack only (contract, ERC20, LP burn≥90, no EOA LP, no stub LP, sell-quote). Query ca= & optional chain=. ~$0.005.

## Output

A compact PASS/FAIL result set for each gate in the playbook: contract validity, ERC20 identity, LP burn percentage (must be ≥90% to pass), EOA LP holder risk (fail if present), stub LP detection (fail if found), and a sell-quote check confirming the token can actually be sold. Each gate returns a PASS or FAIL status, giving a quick go/no-go signal for the token.
