Analyzes a Solana SPL token mint address for rug-pull risk, returning a signed PROCEED|CAUTION|BLOCK verdict with an A–F grade based on mint/freeze authority, Token-2022 traps, holder concentration, LP lock state, and insider networks.

## 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 solidus-solana-token-rug-check-29ce4daf
```

Example prompt: Before I swap into this Solana memecoin, can you rug-check the mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v and tell me if I should PROCEED, CAUTION, or BLOCK — including whether LP is locked and if there are any insider networks or Token-2022 traps?

## When to prefer this

Use this endpoint when you need a fast, fused, single-call safety verdict on a Solana SPL token before executing a swap — especially for memecoins where rug-pull risk is high. It combines on-chain mint/freeze authority checks, Token-2022 trap detection, holder concentration, LP lock state, and Rugcheck depth into one signed verdict, eliminating the need to call multiple data sources separately. Prefer the ?tier=lite variant when budget is tight and only the verdict card is needed.

## Known failure modes

- Invalid or non-existent mint address returns a 400 or error response
- Token not indexed on-chain yet may return incomplete data
- Network timeouts if Solana RPC is congested
- Payment failure via x402 protocol if USDC balance insufficient
- Rate limiting if too many requests in short window

## How this service works

Solana token safety / rug check — Before you sign an SPL swap: is this token a rug? mint/freeze authority, Token-2022 traps, top-10 holder concentration, PLUS rugcheck depth — rugged flag, LP lock state, insider networks, liquidity — fused into one signed PROCEED|CAUTION|BLOCK verdict + grade A–F. Built for memecoin snipers. Tight budget? Add ?tier=lite for a $0.02 verdict-only card (same engine).

## Output

A signed verdict card containing: a PROCEED, CAUTION, or BLOCK decision; an A–F safety grade; rugged flag; LP lock state; mint and freeze authority status; Token-2022 trap indicators; top-10 holder concentration percentage; insider network connections; and liquidity depth metrics.
