# MatrixFold Crypto Token Risk Brief

> MatrixFold Crypto Token Risk Brief is a paid API for AI agents from api-production-853c.up.railway.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Generates an explainable risk assessment brief for a crypto token by checking DexScreener market/liquidity data and GoPlus/RugCheck security signals, returning a risk score, risk level, red flags, and recommended next checks.

## 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 api-production-853c-up-railway-app-b2593b69 -d '<json body>'
```

Example prompt: Before I approve this swap, can you run a risk brief on the token at address 0xabc123...def on Ethereum — I want to see the risk score, any red flags like honeypot or low liquidity, and what checks I should do next?

## When to prefer this

Use this endpoint when an AI agent needs a fast, explainable, multi-source token risk signal before executing or approving a crypto trade, wallet interaction, or token listing — especially when you need human-readable red flags and next-step recommendations rather than raw on-chain data. Prefer this over manual on-chain lookups when you need consolidated DexScreener + GoPlus + RugCheck signals in a single structured response.

## Known failure modes

- Token address not found on the specified chain — returns error with unknown token message
- Chain not supported — returns error indicating unsupported network
- DexScreener or GoPlus/RugCheck APIs unavailable — returns partial results or upstream error
- Invalid or malformed token address — returns validation error
- Payment not provided or insufficient — returns 402 Payment Required

## Output

Returns a structured JSON object with a numeric riskScore, a categorical riskLevel (e.g. low/medium/high/critical), a list of red flags detected (e.g. honeypot, low liquidity, ownership not renounced), recommended next checks for the agent to perform, the data sources consulted (DexScreener, GoPlus, RugCheck), and a non-investment-advice disclaimer.
