## 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 mosn-solana-token-safety-checker-4ad0ee6d -d '<json body>'
```

Example prompt: Can you do a full safety check on this Solana token — mint address So11111111111111111111111111111111111111112 — and tell me if it's SAFE, CAUTION, or DANGER to buy, and why?

## When to prefer this

Use this endpoint when you need a fast, opinionated SAFE/CAUTION/DANGER verdict on a Solana token before trading, with live on-chain checks including sell-route simulation and Token-2022 extension analysis. Prefer this over static metadata checkers when you need real-time holder concentration data (pools excluded) and actual buy/sell flow validation, not just static on-chain attribute lookups.

## Known failure modes

- Invalid or non-existent token mint address returns an error
- RPC or network timeout during live buy/sell simulation
- Token with very low liquidity may produce inconclusive sell-route results
- Token-2022 extension analysis may be incomplete for newly deployed programs
- Transient Solana RPC congestion causing delayed or failed responses

## How this service works

Solana token rug/safety check: mint & freeze authority, dangerous Token-2022 settings, real-wallet holder concentration (pools excluded), sell-route round-trip test, live buy/sell flow. Verdict SAFE/CAUTION/DANGER with reasons.

## Output

Returns a structured verdict of SAFE, CAUTION, or DANGER for the queried Solana token, accompanied by a list of reasons explaining the verdict. Details include mint authority status, freeze authority status, dangerous Token-2022 extension flags, real-wallet holder concentration (with liquidity pools excluded), whether a sell route exists, and the result of a live buy/sell flow simulation.
