## 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 blockpin-solana-control-check-rug-check-87b86bd4
```

Example prompt: Can you run a rug check on the Solana token mint So11111111111111111111111111111111111111112 and tell me if it has mint authority, freeze authority, any Token-2022 extensions like a permanent delegate or transfer fee, and whether the metadata can be changed?

## When to prefer this

Use this endpoint when you need a fast, structured Solana-specific rug check covering both SPL and Token-2022 token mints and on-chain programs. Prefer it over generic blockchain explorers when you need machine-readable risk flags (mint authority, freeze authority, permanent delegate, transfer hook, upgrade authority) rather than raw account data. Especially useful for agents making pre-trade decisions, DeFi due diligence workflows, or platform listing pipelines where automated safety gating on Solana is required.

## Known failure modes

- Invalid base58 address format returns a validation error
- Address not found on Solana mainnet returns a not-found error
- Network or RPC timeout may return a 5xx error
- Passing an Ethereum or non-Solana address will fail the regex pattern validation
- Calling with no address parameter returns a 400 bad request

## How this service works

Solana control check (rug check) for a token mint or program: mint authority, freeze authority, Token-2022 extensions (permanent delegate, transfer hook, transfer fee, default frozen), who can change the name and image, and for a program whether it can still be upgraded and by a single key or a multisig. Use before trading a token or trusting a program. By Blockpin.

## Output

Returns a structured JSON object with a summary string, a risks array listing detected danger flags, a token object (for mints) with fields for mint authority, freeze authority, and Token-2022 extensions (permanent delegate, transfer hook, transfer fee, default frozen, metadata mutability), or a program object (for programs) with upgrade authority info and whether it is multisig-controlled or immutable. Includes metadata such as token name and image where available.
