## 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 trench-lessons-solana-meme-coin-risk-signals-c0b1764c
```

Example prompt: Before I ape into this token, can you run a risk check on the Solana mint address EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v and tell me if there's a curve-skip pool, unlocked LP, Mayhem mode, or bundle handoff flagged, and what the overall risk score is?

## When to prefer this

Use this endpoint when you need fast, lightweight pre-trade risk screening specifically for Solana meme coins on pump.fun or PumpSwap, and want structured boolean flags with confidence levels rather than raw on-chain data parsing. It is purpose-built for the specific risk vectors common in Solana meme coin launches (curve skips, LP locks, bundle manipulation, Mayhem mode) and is cheaper and faster than running your own on-chain analysis.

## Known failure modes

- Invalid or malformed mint address (non-base58 or wrong length) returns a 400 error
- Mint not found on-chain or not a PumpSwap/pump.fun token may return unknown status for all flags
- On-chain RPC timeouts may cause flags to return with status unknown
- Stale data if on-chain state changed after the asOf timestamp
- Payment failure or missing x402 payment header results in 402 response

## How this service works

Trench Lessons: pre-trade risk flags for a Solana meme coin mint (curve-skip PumpSwap pool, unlocked LP, Mayhem mode, bundle handoff) from read-only on-chain data

## Output

A JSON object containing the mint address, a risk score (0–100 integer), the number of scored flags, individual flag objects for curveSkipPool, unlockedLp, mayhemMode, and bundleHandoff (each with a boolean value, status of ok/unknown/n/a, optional detail, and confidence of high/medium/low), an asOf timestamp, and a disclaimer string.
