> RugShield Solana Rug Check is a paid API for AI agents from rugshield-x402.fly.dev, paid per call via x402, $0.01/call, status down (last checked 2026-10-24).

Returns advisory risk flags (SNIPER_FEE_FINGERPRINT, FACTORY_DEPLOYER) with measured precision scores for a Solana pump.fun token mint address to help detect potential rug pulls before buying.

## 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 rugshield-solana-rug-check-a399514e
```

Example prompt: Before I buy this pump.fun token, run a rug check on mint address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU and tell me if it has any SNIPER_FEE_FINGERPRINT or FACTORY_DEPLOYER risk flags.

## When to prefer this

Use this endpoint when you need a fast, cheap ($0.01 USDC) advisory pre-buy risk check specifically for pump.fun Solana tokens and want flag-level signals with empirically measured precision scores. Prefer this over the RugShield Risk Panel when you only need lightweight flag checks rather than aggregated multi-source analysis, and when cost and latency matter. Best suited for automated trading agents or wallets that need a quick sniper/factory-deployer screen before executing a buy.

## Known failure modes

- Invalid or malformed base58 mint address returns an error
- Token address not found on Solana or not a pump.fun token may return no data
- Service unavailability on fly.dev infrastructure
- Payment failure via x402 protocol prevents the call from completing
- NO_FLAGS result may be misinterpreted as a safety guarantee when it is not

## How this service works

Advisory risk flags for a Solana pump.fun token, each with its measured precision. Call before buying a pump.fun token. Input: token mint address (base58). Flags: SNIPER_FEE_FINGERPRINT (recent txs paid fees used by known sniper clusters; 100% precision on 80 rugs + 80 healthy) and FACTORY_DEPLOYER (creator launched 10,000+ tokens with <=2% graduating; 88.9% precision). Returns RISK_FLAGS or NO_FLAGS. NO_FLAGS does not mean safe.

## Output

Returns either RISK_FLAGS (with one or more named flags such as SNIPER_FEE_FINGERPRINT and/or FACTORY_DEPLOYER, each accompanied by a measured precision percentage based on historical backtesting) or NO_FLAGS (indicating no flags were triggered, though this does not guarantee the token is safe). Each flag includes its empirical precision score so the agent can assess confidence in the signal.
